SET-UP PROCEDURES
The stump grinder is shipped with a slip clutch PTO shaft
that can be fitted to most Category 1 tractors. The PTO
shaft may need to be trimmed depending on your tractor
and configuration. Follow the steps below to ensure the
PTO shaft is correctly fitted to your tractor.
Verify the distance between the locking pins on the PTO
shaft while in the compressed state(Dim B) as shown
in the image below. It should measure 34" (862.5 mm).
If Dim A is at least 1" (25 mm) longer than Dim B, the
PTO shaft does not require trimming. It is recommend-
ed the shaft not be used if there is less than 6" (150
mm) of overlap between the two halves of the PTO
shaft when the equipment is in the operating position.
If Dim B is longer than Dim A, the PTO shaft will require
trimming. Use this equation to calculate the correct
amount to trim:
Note: the slip clutch end of the PTO shaft mounts to the
stump grinder.
After trimming both halves of the PTO shaft, use a file to
remove any burrs or sharp edges and slide the halves back
together, ensuring they telescope in-and-out freely. The
PTO shaft is now ready to connect the stump grinder to the
tractor for operation.
(B- A) +1 inch =C (Amount to Trim)
Once C has been calculated, trim that amount from BOTH
halves of the PTO shaft safety cover first, then trim the
same amount from both shafts. This will ensure the
safety cover on each end remains a few inches back from
the ends of the shafts, otherwise PTO shaft reassembly
could be difficult.
ƒ Attach the stump grinder to the tractor's 3-point
hitch system. Do not install the PTO shaft.
ƒ Raise the stump grinder so that the shaft on the
tractor is in line with the shaft on the stump grinder.
ƒ Measure the distance between the locking grooves
on the splined shafts of the tractor and stump grind-
er (Dim A) as shown below:
