Frequently Asked Questions

  • Q: What are the benefits among the different models?

    A: The answer depends on your property and personal preferences. If you currently enjoy mowing your lawn with a riding tractor, or if you're planning to get a rider, one of our Tow-Behind models may be ideal. These leaf collection machines work very fast and cover large areas quickly. Their extra large capacities mean you can work longer without having to empty collected debris. And with a 10:1 reduction they shred material into very fine mulch. Plus, with a Tow-Behind Leaf and Lawn Vacuum, you can work in ride-on comfort!

    The Self-Propelled Leaf and Lawn Vacuum is a great choice if you don't own a riding tractor...or if you simply prefer to walk while you work. The Self-Propelled machines are perfect for leaf collection in highly landscaped areas. They can easily get into places where a rider and Tow-Behind unit simply wouldn't fit. Steep slopes (up to 20°) - where you wouldn't take a rider - are also better-suited to a Self-Propelled model. Finally, if your yard is on the smaller side, a Self-Propelled model may be all the machine you need.

  • Q: Are they easy to start?

    A: The electric-starting models have a powerful battery that recharges as the engine runs, and they start instantly with the turn of key or flip of a switch. The manual-starting models feature compression release and electronic ignitions, for quick starts with one or two easy pulls.

  • Q: Can I use the Leaf and Lawn Vacuum on hills?

    A: Yes, the Self-Propelled and Tow-Behind models can be used on slopes up to 15° for Tow-Behind Leaf & Lawn Vacuum as per the Owner's Manual.

  • Q: How are DR products shipped?

    A: We offer 3 basic options:
    1) Delivery to a Depot
    2) Delivery to Home or Business
    3) Enhanced Home Delivery

  • Q: What happens if my machine needs service?

    A: If you ever have questions about your DR® Leaf and Lawn Vacuum, you can use our Owner Support area. It offers a rich resource of information including troubleshooting, Owner's Manuals and replacement parts. Should you have additional questions, one of our Product Specialists can help you. These folks have in-depth knowledge of the DR® Leaf and Lawn Vacuum. They've spent many hours in training and they have also put the machine through its paces mowing in a variety of conditions, so they know what they're talking about. If necessary, we can get replacement parts to you right away or direct you to one of more than 1,500 authorized DR Friendly Service Centers nationwide.

  • Q: How does your 6 Month Trial work?

    A: Simply put, you can try it on your own property for up to 6-months!

  • Q: What is your Warranty?

    A: 2 Years for Residential Use, 30 Days for Commercial Use.

Tips & Tricks

Leaf and Lawn Vacuum Tow Behind Model

Tow-Behind Models

The following information is provided to demonstrate proper techniques when operating your DR Leaf and Lawn Vacuum.

Note: This information pertains to the most recent Leaf and Lawn Vacuum models. Please refer to your Safety & Owner's Manual for instructions specific to your machine. Please refer to the Engine Owner's Manual for engine specific instructions.

Warning: Pick up stones, metal objects, glass and sticks before vacuuming.

Efficient uses of the DR Leaf and Lawn Vacuum

For the most efficient use of the DR Leaf and Lawn Vacuum, use this sequence of steps:

  1. Gather and pile sticks for chipping.
  2. Chip the smaller sticks and branches.
  3. Remove the Rear Panel and load the larger limbs.
  4. Dump the load at the desired location.
  5. Mow and vacuum leaves.

Be careful in corners

Practice in first gear to understand the effects of the Trailer on your ability to turn sharply. Drive your DR Leaf and Lawn Vacuum into the corner of your property and back out straight to mow as close to the corner as possible. Be sure to say away from fences when you want to turn, as the back will swing wide during a turn. Avoid going through ditches.

Easily attach accessories to the Collector Box

Vacuum with the discharge side toward the leaves

The Lawn Deck will tend to scatter some leaves in front and to the right of the Lawn Deck. Keeping the discharge side toward the remaining leaves will simplify cleanup by avoiding blowing leaves back onto the areas that you already finished. When you need to vacuum with the discharge side toward the completed area of the lawn, then overlap the discharge side of the Lawn Deck at least a foot over the already completed section of the lawn.

Keep grass length and cutting height low for optimal performance

To prevent clogging the Lawn Deck Adapter and Vacuum Hose, mow grass that is dry and not more 2" at a time. To keep your grass healthy, we recommend cutting less than 1/3 the grass height.

Maximize lift from your lawn deck

Run your Lawn Deck with your Tractor at full throttle all the time to maximize the lift from your Lawn Deck and assist your DR Leaf and Lawn Vacuum system.

Watch for curbs, stonewalls, and debris

Avoid dragging the Inlet Hose over curbs, stonewalls, or piles of cut branches. The Hose is tough, but can puncture on sharp objects. This could also crack the Mower Deck Adapter.

  • We recommend wearing long pants and gloves while using your DR Leaf and Lawn Vacuum. Be sure your gloves fit properly and do not have loose cuffs or drawstrings.
  • We recommend the use of ear protectors or ear plugs rated for at least 20 DBA to protect your hearing.

Operating the Vacuum Safely

This is a high-powered machine, with moving parts operating at high energy at high speeds. You must operate this machine safely. Unsafe operation can create a number of hazards for you, as well as anyone else in the nearby area. Always take the following precautions when operating this machine:

  • Allow only responsible individuals who are familiar with these general safety rules and operating instructions to use your DR Leaf and Lawn Vacuum. Never allow people who are unfamiliar with these instructions to use the machine.
  • Keep bystanders at least 100 feet away from your work area at all times. To be safe, do not operate the machine near small children or pets, and never allow children to operate the vacuum. Stop the vacuum engine and tractor engine when another person or pet approaches.
  • Clear the work area of objects such as rocks, string-like material, wires, rope, or rags. Ingesting these objects into the vacuum could damage the machine and/or cause injury.
  • Be sure all controls are disengaged before attempting to start the engine.
  • Never place your hands, feet, or any part of your body near or under any moving part while the machine is running.
  • Do not touch the exhaust area, including the muffler and engine when the machine is in use as they become very hot and can cause a severe burn. Allow the engine to cool before doing maintenance or making adjustments.
  • Keep combustible substances away from the engine.
  • Never, under any conditions, remove, bend, cut, fit, weld, or otherwise alter standard parts on the DR Leaf and Lawn Vacuum. This includes all shields and guards. Modifications to your machine could cause personal injuries and property damage and will void your warranty.
  • Do not alter or tamper with safety devices or shields. Make sure they are in proper position.
  • Do not operate in sandy areas where you will vacuum large quantities of sand. Sand will erode the vacuum housing. Check for pin holes after each use and replace the hose or housing when pin holes develop.
  • Keep your hands and combustible substances away from the engine when it is hot and clean the engine area after each use.
  • For Walk-Behind Models: Never operate the machine on slopes greater than 20°.
  • For Walk-Behind Models: Never use the machine with the debris bag removed.
  • For Walk-Behind Models: Always wear gloves when emptying the debris bag.
  • For Walk-Behind Models: After vacuuming glass, bottles or cans, dispose of this waste properly, never in a compost pile.
  • For Walk-Behind Models: We recommend changing both the optional disposable debris bag liner and the outer debris bag after vacuuming glass and other debris and before using the system to vacuum material that may be used for compost or mulch.
  • For Tow-Behind Models: Never allow people or pets to ride in the collector box or on the trailer.
  • For Tow-Behind Models: Never start the blower/chipper engine unless it is bolted firmly to the engine mounting plate and the mounting plate is attached firmly to the trailer chassis using the four (4) retaining knobs. See your Owner's Manual.
  • For Tow-Behind Models: Check behind your DR Leaf and Lawn Vacuum before backing up. You cannot see directly behind the collector box.
  • For Tow-Behind Models: Never attempt to dump a load while the lawn tractor engine or the DR Leaf and Lawn Vacuum engine is running.
  • For Tow-Behind Models: Do not attempt to open the collector box when your DR Leaf and Lawn Vacuum engine or your lawn deck engine is operating. Debris may exit at high velocity out of the small openings created in the seams of the collector box as you unlatch the collector box panels.
  • For Tow-Behind Models: Never operate the machine on slopes greater than 15?.
  • For Tow-Behind Models: When using the DR Leaf and Lawn Vacuum as a trailer, be sure to secure the load.
  • For Tow-Behind Models: Never tow the DR Leaf and Lawn Vacuum faster than 8 mph.
  • For Tow-Behind Models: Keep your hands out of the chipper hopper and vacuum inlets while the lawn tractor and the DR Leaf and Lawn Vacuum engines are running. If it becomes necessary to push material into the hopper, use a small diameter stick.
  • For Tow-Behind Models: Always shut off the lawn tractor engine and the DR Leaf and Lawn Vacuum engine, and disconnect the spark plug wire before attempting to clear any obstructions in the hoses or chipper hopper.
  • For Tow-Behind Models: Always feed the chipper from the chipping zone (see your Owner's Manual). Never straddle or reach over the engine area at any time.
  • For Tow-Behind Models: Use only your hands to operate the DR Leaf and Lawn Vacuum engine controls. Always dismount your lawn tractor when starting and stopping the DR Leaf and Lawn Vacuum engine to prevent contact with the hot muffler.

Slope Operation

Slopes are a major factor related to slip and fall, or tip over accidents, which can result in severe injury. All slopes require caution. If you feel uneasy on a slope, do not vacuum it. Always take the following precautions when using this machine on slopes:

  • For Walk-Behind Models: Mow across the face of slopes; never up and down. Exercise extreme caution when changing direction on slopes.
  • For Tow-Behind Models: Mow up and down the face of slopes and never across. Exercise extreme caution when changing direction on slopes.
  • Always remove objects such as glass, large sticks, stones, metal objects, wire, rope, rags, and string-like material.
  • Always watch out for holes, ruts, or bumps. Tall grass can hide obstacles.
  • Never mow near drop-offs, ditches, or embankments. You could lose control of your lawn tractor (if applicable) and machine, or your footing or balance.
  • Never mow on slopes greater than 20 degrees (15 degrees for Tow-Behind Models) or any excessively steep slopes. For Tow-Behind Models, see the Operating Parameters in your Owner's Manual for further restrictions relating to your lawn tractor.
  • Never mow on wet or slippery slopes. Reduced traction could result in slipping and a possible roll over.
  • Never park the vacuum or lawn tractor (if applicable) on a steep grade or slope.

Safety for Children and Pets

Tragic accidents can occur if the operator is not alert to the presence of children or pets. Children are often attracted to the tractor and the vacuuming/chipping activity. Never assume that children will remain where you last saw them.

  • Keep children and pets out of the work area and under the watchful care of a responsible adult.
  • Be alert and always turn off the lawn tractor (if applicable) and the DR Leaf and Lawn Vacuum engine if children or pets enter the work area.
  • Before and while moving backwards, look behind, and down for small children and pets. With Tow-Behind Models you cannot see directly behind the collector box.
  • Never allow children to operate the lawn tractor or DR Leaf and Lawn Vacuum.
  • Use extra care when approaching blind corners, shrubs, trees, or other objects that may obscure your vision.
  • Never allow children to operate the lawn tractor (if applicable) or vacuum, even if the engine is not running.
  • For Tow-Behind Models: Never allow children to play in the collector box. if they become trapped in the enclosure they may be exposed to temperatures similar to leaving a child in a car with the windows closed on a sunny day.

Safety with Gasoline-Powered Machines

Gasoline is a highly flammable liquid. Gasoline also gives off flammable vapor that can be easily ignited and cause a fire or explosion. Never overlook the hazards of gasoline. Always follow these precautions:

  • Never run the engine in an enclosed area or without proper ventilation as the exhaust from the engine contains carbon monoxide, which is an odorless, tasteless, and deadly poisonous gas.
  • Store all fuel and oil in containers specifically designed and approved for this purpose and keep away from heat and open flame, and out of the reach of children.
  • Fill the gasoline tank outdoors with the engine off and allow the engine to cool completely. Do not handle gasoline if you or anyone nearby is smoking, or if you're near anything that could cause it to ignite or explode. Replace the fuel tank and fuel container caps securely.
  • If you spill gasoline, do not attempt to start the engine. Move the machine away from the area of the spill and avoid creating any source of ignition until the gas vapors have dissipated. Wipe up any spilled fuel to prevent a fire hazard and properly dispose of the waste.
  • Allow the engine to cool completely and empty the collector box before storing the DR Leaf and Lawn Vacuum in any enclosure. Remember, decomposing material can generate heat and start a fire. Never store the machine with gas in the tank or a fuel container, near an open flame or spark such as a water heater, space heater, clothes dryer or furnace.
  • Never make adjustments or repairs with the engine running. Disconnect the spark plug wire and keep the wire away from the spark plug to prevent accidental starting.
  • Never check for an ignition spark with the spark plug or spark plug wire removed. Always use an approved spark plug tester.
  • Never tamper with safety devices. Regularly check their proper operation.
  • Never tamper with the engine's governor setting or modify the engine speed. The governor controls the maximum safe operating speed and protects the engine. Over-speeding the engine is dangerous and will cause damage to the engine and to the other moving parts of the machine. If required, see your authorized engine dealer for engine governor adjustments.
  • To reduce fire hazard, keep the engine and muffler area free of debris build-up such as leaves, grass, oil, grease, or any other combustible material. Clean the engine area after each use.
  • Do not operate the engine with the air cleaner or the cover over the carburetor air-intake removed, except for adjustment. Removal of such parts could create a fire hazard.
  • Never operate the engine without the muffler. Inspect the muffler periodically and replace if necessary. If equipped with a muffler deflector, inspect the deflector periodically and replace if necessary.
  • Always check fuel lines and fittings frequently for cracks or leaks, replace if necessary.

General Safety

The DR Leaf and Lawn Vacuum must be operated safely to prevent or minimize the risk of minor or moderate injury. Unsafe operation can create a number of hazards for you. Always take the following precautions when operating this machine:

  • Keep in mind that the operator or user is responsible for accidents or hazards occurring to other people, their property, and themselves.
  • Your DR Leaf and Lawn Vacuum is a powerful tool, not a plaything. Exercise extreme caution at all times. The design of this machine is to vacuum debris. Do not use it for any other purpose.
  • Know how to stop the vacuum quickly; see your Owner's Manual.
  • Use the DR Leaf and Lawn Vacuum only in daylight.

If the machine should start making an unusual noise or vibration, immediately shut off the engine, disconnect the spark plug wire, allow all moving parts to come to a complete stop, and wait five (5) minutes to cool. Disconnect the spark plug wire and inspect for clogging, damaged, or worn impeller, loose impeller bolt, loose impeller key, or loose engine mounting bolts. Clean and repair and/or replace damaged parts.
  • Always shut off the DR Leaf and Lawn Vacuum engine, wait five (5) minutes to cool, and disconnect the spark plug wire before attempting to clear any obstructions.
  • Always keep the equipment in a good safe operating condition. Always make certain nuts and bolts are tight and always use the supplied self-locking hardware; do not substitute.
  • For Walk-Behind Models: Never start the engine without the debris bag attached firmly to the top shield assembly. See your Owner's Manual.
  • For Walk-Behind Models: Never attempt to remove the debris bag while the DR Leaf and Lawn Vacuum engine is running. Debris may exit at high velocity out of the openings created in the seams as you unlatch the debris bag.
  • For Walk-Behind Models: Empty the debris bag after each use to prevent spontaneous combustion due to decaying material.
  • For Tow-Behind Models: Remove side branches before chipping to prevent jamming the material in the chipper hopper.
  • For Tow-Behind Models: Do not attempt to chip wood larger than specified in this manual.
  • For Tow-Behind Models: Never use the DR Leaf and Lawn Vacuum to vacuum anything but yard waste, such as leaves, grass, small twigs and pine cones.
  • See manufacturer's instructions for proper operation and installation of accessories. Only use accessories approved by DR Power Equipment, Inc.
  • No list of warnings and cautions can be all-inclusive. If situations occur that are not covered by this manual, the operator must apply common sense and operate the DR Leaf and Lawn Vacuum in a safe manner.

The following information is provided to demonstrate proper techniques when storing your DR Leaf and Lawn Vacuum.

Note: This information pertains to the most recent Leaf and Lawn Vacuum models. Please refer to your Safety & Owner's Manual for instructions specific to your machine. Please refer to the Engine Owner's Manual for engine specific instructions.

When performing any maintenance, you must first shut off the engine, wait five (5) minutes for all parts to stop and cool, and disconnect the spark plug wire, keeping it away from the spark plug. Read the safety considerations section of your Owner's Manual before performing any repairs or maintenance.

End-of-Season Procedure

  • Change the oil.
  • If your DR Walk-Behind Leaf and Lawn Vacuum will be idle for more than 30 days, we recommend using a gas stabilizer. This will prevent sediment from gumming up the carburetor. If there is dirt or moisture in the gas or tank, remove it by draining the tank. Completely fill the tank with fresh, unleaded gas and add the appropriate amount of stabilizer or gasoline additive. Run the engine for a short time to allow the additive to circulate.
  • Remove the spark plug and pour about 1 ounce of motor oil into the cylinder hole. Replace the plug and pull the recoil starter rope until you feel strong resistance. This will coat the piston and seat the valves to prevent moisture buildup.
  • Clean or replace the air filter.
  • Clean dirt and debris from the cylinder head cooling fins, impeller housing, debris screen, and muffler area of the engine.
  • Clean the Debris Bag. For Step-by-Step Instructions on removing and emptying the Debris Bag, see your Owner's Manual.
  • For Electric-Start models, store the Battery in a dry area that will not freeze. If you will not use the machine over a long period, charge the Battery every four to six weeks. See your Owner's Manual for more information on Battery Care.
