4. 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).

4. 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).

5. If Dim A is at least 1” (25 mm) longer than Dim B, the PTO shaft does not require trimming.

It is recommended 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.

6. If Dim B is longer than Dim A, the PTO shaft will require trimming. Use this equation to

calculate the correct amount to trim:

(B - A) + 1 inch = C (Amount to Trim)

7. Once Chas been calculated, trim that amount from BOTH halves of the PTO shaft safety

cover Þrst, 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 difÞcult.

8. After trimming both halves of the PTO shaft, use a Þle 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.

6. Reverse over a tree stump and lower the stump grinder so it will remove 2” (50 mm) per pass. Always

ensure the grinder is cutting properly and not jumping around erratically.

7. Once the stump is at ground level, continue to take up to 2” (50 mm) deep passes until the stump and

roots are 4-6” (100-150 mm) below grade. Keep a watch out for foreign objects below the soil like rocks

or buried metal. These can damage or break the teeth resulting in poor grinding performance.

8. During use, it is important to never let the stump grinder sway beyond an angle that will allow the PTO

shaft to separate. Do not operate the stump grinder with less than 6” (150 mm) of overlap between the

two halves of the PTO shaft. If the stump grinder begins to sway, it means either the tractor is advancing

faster than the grinder can remove material or that too much material is being removed per pass. If this

is observed, immediately stop moving forward and position the tractor and stump grinder in a manner so

that it is in the vertical position. Take a slower pass and/or shallower cut if necessary.

area in the lower-left quadrant as shown below:

STUMP GRINDING PROCEDURE

The ßywheel spins in a clockwise manner (when facing the rear of the machine) with the

effective cutting area in the lower-left quadrant as shown below:

Therefore, when grinding a tree stump, always start from the right side of the stump, moving

incrementally to the left, pulling the grinder straight forward through the stump on each pass.

When grinding softwoods like pine, spruce, or poplar, it may be permissible to remove upwards

of 2Ó (50 mm) of material per pass. However, hardwoods like oak, ash, and birch can be much

more dense and the depth of grind may only be up to 1Ó (25 mm). If the chassis is swaying like

described in the previous section, or the grinder is vibrating or bouncing, reduce the depth of

cut or feed rate accordingly.
