STUMP GRINDER SET-UP PROCEDURES TRIMMING THE PTO SHAFT
The stump grinder is shipped with a PTO shaft that can be fitted to most tractors. The
PTO shaft may need to be trimmed depending on your tractor and configuration.
Follow the below steps to ensure that the PTO shaft is fitted to your tractor correctly.
1. Attach the stump grinder to the tractor, but do not install the PTO shaft.
2. Raise the stump grinder using the tractors 3 point hitch system so that the shaft on
the tractor is level with the shaft on the stump grinder.
3. Measure the distance between the locking grooves on the shaft of the tractor and
stump grinder (A) as shown below.
4. Measure the distance between the locking pins on the PTO shaft itself when it is in
the compressed/shortest length (B) as shown below.
5. If(A) is at least 1” longer than (B), the PTO shaft will not need to be cut.
6. If dimension (B) is longer than (A), the PTO shaft will need to be cut. The below
equation may be used to calculate the correct amount to trim.
(B-A) + 1 INCH = C (AMOUNT TO CUT)
7. Once (C) has been calculated; this amount will need to be cut off of BOTH
halves of the PTO shaft.
8. After both halves of the PTO shaft have been cut, use a file to remove any burrs or
sharp edges and slide the shaft together ensuring it telescopes in and out freely. The
PTO shaft can now be attached to the stump grinder and tractor, ready for use.

1. Proper and routine maintenance is critical to operator safety, achieving
proper stump grinding results and in prolonging the life of the machine.
2. For cleaning and maintenance of the stump grinder, switch off the tractor PTO shaft and
turn the engine off.
3. Inspect the unit before each use for loose nuts and worn cutting teeth. Also clean
any build up of debris.
4. After 2 hours of operation, check for loose nuts and worn cutting teeth. Tighten and
replace as necessary.
5. Grease the bearings and the pivot pins on the main housing as needed before eachuse. Do
not over grease the the bearings as this will blow out the seals and causepremature bearing
failure.
6. Inspect the clutch plates on the PTO shaft periodically to ensure that they are not seized
together. Refer to “PTO Shaft Clutch Run In” in the “Stump Grinder Set UpProcedures”
section of the manual.
