6. Take the underseat shield. Position it
around the seat track mount area and
around the controls. Ensure that the
shield will not interfere with the
operation of any of the controls. Slit the
centre area to provide access to the seat
track mounting bolts. Bolt into place
under the seat track. See Figure 5.

place, and lower the cab straight down
onto the tractor. Ensure that the top
protrusion on the isolator fits into the
cab mount plate hole and attach all
mounts bolts. As soon as all bolts have
been started, torque all the mounts to

then reinstall the valve mounting plate
onto the loader at the loader subframe,
and then install the safety stop mount
cover plate onto the hydraulic valve, and
then the shield onto the cab frame with
the same fasteners that the lower front
right window uses. The fit is VERY tight
and may take a little way to get all the
components fit properly. See Figure 14.

17. Locate the heater hose coming out of
the cab frame at the bottom of the
A-post. Route the hoses into the engine
compartment, being careful that they do
not interfere with any moving parts, tie
down as necessary. Using the labels on
the hose, route hose to pressure and
suction sides, ensure that there is
adequate hose to each fitting, and then
cut the hose. Attach the hoses to the
fittings using the HS-6 hose clamps

the factory hardware. See Figure 20.
18. Make sure there are no leaks, then
start the engine, open cab heater valve,
and turn on fan, and run at PTO RPM to Figure 20
build up engine heat, engine coolant
must become hot to produce hot air.
Keep the radiator cap off to purge the
system of trapped air, and continue to fill
antifreeze as required. Continue to run
the engine and add antifreeze until
heater produces HOT AIR!
19. Take the three floormat pieces.
Position the left cab frame piece over the
shield extension and glue into place.
Position the right part over the shield
extension on the right side and glue into
place. Take the large centre floormat
and place over floormat on platform.
Ensure that all pedal controls have
adequate clearance, and then glue into
place. See Figure 19.

against moisture penetration, use a
black urethane sealant on all cracks and
small openings between floormats and
front shields.
