General Safety
Operating this DR 42" Lawn Mower Deck safely is necessary to prevent or minimize the risk of death or serious injury. Unsafe
operation can create a number of hazards for you. Always take the following precautions when operating this Lawn Mower Deck:
• This is a high-powered machine, with moving parts operating with high energy at high speeds. You must use proper clothing
and safety gear when operating this machine to prevent or minimize the risk of severe injury. This machine can cut and sever
parts of your body if they contact the Moving Blades.
• Thoroughly inspect the area in which you will be working and remove all foreign objects. Clear the area of objects such as
Rocks, Toys, Wire, Bones, Sticks, Glass etc., which could be picked up and thrown by the Blades which could damage the
machine and/or cause injury.
• Read this Safety & Operating Manual before you use the DR 42" Lawn Mower Deck. Become familiar with the operation and
service recommendations to ensure the best performance from your Lawn Mower Deck.
• Never allow people who are unfamiliar with these instructions to use the Mower. Allow only responsible individuals who are
familiar with these rules of safe operation to use your machine.
• Keep your hands and feet away from the Blades, Belts, Blade Pulleys, and concealed areas while the engine is running. Never
reach under the Deck or grab hold of any part of the Deck when the Engine is running.
• Never use the Mower with the Discharge Chute removed.
• Never, under any conditions, remove, bend, cut, fit, weld, or otherwise alter standard parts on the dr 42" Lawn Mower Deck.
This includes all Shields and Guards. Modifications to your machine could cause personal injuries and property damage and
will void your warranty.
• Your DR 42" Lawn Mower Deck is a powerful tool, not a plaything. Exercise extreme caution at all times. The design of this
machine is to cut grass. Do not use it for any other purpose.
• Be sure all Blade and Wheel controls are disengaged before attempting to start the Engine. Engage and disengage the Mower
Blades a few times to get used to it before mowing.
• If you have to stop to remove grass or debris from the underside of the Deck, always shut off the Engine, allow the Engine to
cool five (5) minutes and remove the Spark Plug Wire(s) before removing grass or debris.
• Know how to stop the Blades quickly; see page 8.
• Stop the Blades when crossing gravel drives, walks, or roads.
• Always operate the Mower from behind. Never pass or stand on the discharge (right) side or in front of machine when the
Engine is running.
• Do not pull the Mower backwards unless absolutely necessary. Look down and behind before, and while moving backwards.
• If the machine starts to make an unusual noise or vibration, immediately shut off the Engine and wait five (5) minutes for all
moving parts to come to a complete stop and cool. Disconnect the Spark Plug Wire(s). Vibration is generally a warning of
trouble. Inspect for clogging or damage. Clean and repair and/or replace damaged parts.
• Keep all Nuts and Bolts tight, especially the Blade attachment Bolts, and keep the equipment in good operating condition.
• The Mower blades are sharp and can cut. Wrap the blades or wear gloves, and use extra caution when servicing.
• Keep bystanders at least 100 feet away from your work area at all times. Objects can be thrown far from the Mower and at
great speeds. To be safe, do not operate the machine near small children or pets, and never allow children to operate the
Mower. Disengage the Blades and stop the Engine when another person or pet approaches.
• Refer to your DR
Warnings and Cautions. If you have any questions or need assistance, please contact us at www.DRpower.com or call toll-free

Mounting the Front Caster Wheels
NOTE: The Caster Wheels mount on the Front Arms of the Deck Frame (Figure 2).
1. Insert two black Castor Wheel Spindle Bushings (one on top and one on the
bottom) into a Front Arm of the Lawn Deck Frame. You may need to tap the
Bushings in with a Hammer (Figure 3).
2. Insert the Caster Wheel Spindle into the Bushings from the bottom(Figure
4). Push the Cotter Pin into the Hole in the Spindle as far as it will go.
3. Hold the Tire with one hand to keep the Axle from turning while bending the
legs of the Cotter Pin with Pliers. Bend the long leg first, then the shorter
leg.
4. Repeat steps 1-3 for assembly of the remaining Caster Wheel.
If you remove the Cotter Pins, replace them with new ones 1/4" in diameter
and 1-1/2" long. Repeated straightening and bending will break the Cotter
Pins at the bend, and may cause the Caster Wheels to come off during
operation causing severe damage or possible injury.

Height Adjustment Lever. After adjusting to a new height, re-insert the
Clevis (Figure 9).
NOTE: You can adjust the cutting height of the Mower Deck in 1/2" increments.
The Clevis Pin prevents accidental dislodging of the Cutting Height Adjustment Lever
over rough terrain.
The mower engine's power can easily throw stones, sticks, and other debris at great velocity, which could cause personal injury or
property damage. Never run the machine over gravel driveways or over loose stones or mulch with the mower deck blades
spinning.
• Always check your work area before mowing and remove any debris that might tangle or damage the machine.
• If you do run into debris and the Mower Deck becomes tangled, turn off the engine and disconnect the spark plug wire(s)
before attempting to untangle the machine.
