Replace only one tine at a time. This will help to insure
the correct positioning of the tines as they are mounted
on the tine assembly. When installing the new tine, be
certain that the longer shoulder bolt is in the inner hole
toward the center of the tine assembly. Realign the
bolts and washers as shown in Figure 21 and retighten
firmly.

Changing Hydraulic Pump Drive Belt
Allow the machine to cool before performing
maintenance. The muffler and belts will
become hot during normal use.
Figure 22
The hydraulic pump drive belt is located under the
tractor and is driven by the PTO of the tractor. To
remove the belt for inspection or replacement, proceed
as follows:
• Crouch or lie next to the tractor on the right side and
locate the hydraulic pump assembly underneath
the center of the tractor frame. Refer to Figure 22.
• The idler pulley on the right side is attached to the
idler arm and is spring loaded to provide constant
tension to the pulley which keeps the belt tight.
• There is a 3/8” square hole on the outside edge of
the idler arm which is used to relieve belt tension.
Insert the head of a 3/8” ratchet into the square
hole.
• With the ratchet set to tighten, pull on the ratchet
and notice that belt tension is being loosened.
• While holding the ratchet to keep the belt loose,
carefully remove the belt from the large hydraulic
pump pulley and the other stationary idler pulley.
• With the belt removed from the hydraulic pump
assembly, raise the hood of the tractor and locate
the belt where it rests in the pulley of the PTO. The
belt at this point is free of obstruction and can be
removed through the hood opening.
Inspect the belt for any cracks or fraying. Replace if
necessary. Before installing a new belt, check pulley
shafts and bearings for excessive end play and wear.
Make certain that they turn smoothly and freely.
Check pulley grooves for debris build-up or wear. If the
pulleys require cleaning, moisten a cloth with a non-
flammable degreasing agent to clean out the grooves.
Refer to the Mounting the Tiller section earlier in this
manual for instructions on installing the hydraulic pump
drive belt.
Hydraulic Hoses
WARNING: Hydraulic hoses, fittings, and
fluid become hot during normal usage. Allow
the machine and its related hardware to cool
down before performing maintenance.
The hydraulic hoses need to be checked regularly for
cracks or leaks. Hydraulic fittings also need to be
checked for leaks or damage. Replace any hose that
shows signs of cracking or leaking to avoid a
dangerous situation.
Hydraulic fittings that are leaking should be checked to
verify that they are tight. If further leaking persists after
tightening, the fitting or the hose may need to be
replaced.
If fluid is lost during repairs, be sure to check the fluid
level and add as necessary.
