Chapter 3: Operating Your 3-POINT HITCH DR SELF-FEEDING CHIPPER 

This chapter covers the procedures for starting and stopping your new 3-POINT HITCH DR SELF-FEEDING CHIPPER and 
discusses basic operation features. 

Starting the Chipper 

NOTE: 

Some tractors may require the use of an

 

Over Running Clutch.  Consult your local dealer for more information. 

1.

 

Ensure that the Chipper is lowered to the ground and all Guards are in place and properly secured before using. 

2.

 

Remove any debris buildup from the machine before every use of the Chipper. 

3.

 

Set Tractor throttle at IDLE before engaging PTO with Chipper attached. 

4.

 

Increase Tractor throttle to the RUN RPM’s required to obtain 540 PTO speed before chipping. 

5.

 

Reduce Tractor throttle to IDLE before disengaging PTO. 

NOTE:

  Check the Drive Belt, if necessary, after an initial break-in period of one (1) hour (see Chapter 5 “Maintaining the 3-POINT 

HITCH DR SELF-FEEDING CHIPPER”). 

 

This machine is designed to operate at 540 rpm only!  Never operate the machine at a faster speed; doing so can cause 
serious injury to the operator or bystanders and could cause damage to the machine that is not covered under warranty. 

 

The DR 3-Point Hitch Chipper must be operated with the weight of the machine on the ground.  Operating the machine while 
it is off the ground can result in injury to yourself or others, and can cause damage to the machine which is not covered under 
warranty. 

 

The design of this machine is for chipping wood.  Never use this machine for any other purpose as it could cause serious 
injury. 

 

Contact with internal rotating parts will cause serious personal injury.  Never put hands, face, feet, or clothing into chipper 
hopper or discharge opening or near the discharge area or PTO shaft at any time. 

 

Disengage PTO, shut down the tractor engine, remove the key, wait for all moving parts to come to a complete stop, 
disconnect the PTO shaft from the tractor, then wait 5 minutes before moving or performing maintenance/inspection on the 
chipper.  Use only a wooden stick to clear jammed material. 

 

Never operate the machine without the hopper or discharge chute or PTO shaft properly installed.
