Chapter 3: Operating Your 3-POINT HITCH MIGHTY MAC GRAVITY SELF-FEEDING CHIPPER
This chapter covers the procedures for starting and stopping your new 3-POINT HITCH MIGHTY MAC GRAVITY SELF-FEEDING
CHIPPER and discusses basic operation features.
• 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 Mighty Mac 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.
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 MIGHTY MAC GRAVITY SELF-FEEDING CHIPPER”).
