Attaching the Hydraulic Pump Assembly
To mount the hydraulic pump assembly to the tractor,
make certain that it is placed under the center of the
tractor’s frame, resting on the ground, with the hydraulic
hoses attached. Connect the hydraulic pump assembly
as follows:
• The rear of the hydraulic pump assembly has a
“tongue” on it. The tongue is the flat portion toward
the rear of the assembly. Raise the rear of the
assembly up and slide the tongue into the slotted
portion of the rear mounting bracket. Refer to
Figure 13.
• Before raising the front of the hydraulic pump
assembly, remove the front hanger rod by removing
one of the hairpin clips and sliding the rod out.
• Lift the front of the hydraulic pump assembly and
align the holes in the assembly with the holes in the
side frame brackets.
• Install the front hanger rod and secure with the
hairpin clip removed earlier.
With the hydraulic pump assembly installed, locate the
sleeve that surrounds the two hydraulic hoses and slide
it toward the hydraulic pump as far as possible. This will
provide more protection to the hydraulic hoses where it
is necessary.
Installing the PTO Drive Belt
The hydraulic pump drive belt needs to be installed.
This belt connects the tractor’s PTO to the hydraulic
pump which provides power to the tiller attachment.
The following describes how the belt is installed:
• Raise the hood of the tractor and locate the PTO
pulley on the front of the engine.
• Working from the engine compartment, feed the
belt around the front of the PTO pulley and place
the last portion of the belt onto the pulley with the V-
groove of the belt facing into the pulley.
Figure 13
• Lying down on the right side of the tractor, take the
loose portion of the belt and pull it toward the back
of the tractor.
• Keeping light tension on the belt, align the V-groove
of the belt into both mule drive pulleys mounted
slightly in front of the front axle of the tractor. There
should be a single 90° twist of the belt between the
PTO pulley and each mule drive pulley.
• Place a 3/8” ratchet head, set to tighten, into the
square hole near the right hand idler pulley and
apply force. Notice how the pulley moves toward
the outside of the tractor. Doing this will make
installing the remainder of the belt easier.
• Making certain that the belt has a single 90° twist
between the mule drive pulleys and the idler
pulleys, and that the flat side of the belt is resting on
the idlers, apply pressure to the ratchet and finish
routing the belt around the hydraulic pump pulley.
Be sure that the V-groove of the belt is set
completely in the pulley before releasing the
ratchet.
• Recheck the routing of the belt to ensure that it is
resting completely in all the grooves of all the
pulleys before engaging the PTO.
