ENGINE MUST BE COOL BEFORE DISCONNECTING THE HOSES.
1. Assemble pusher bars (Ref# 14 and 17) to plow blade (Ref# 6) using one

bolt (Ref# 10) and
one

-16 x 3 bolt (Ref#11) per pusher bar. There are 2 holes to bolt (Ref# 10) hardware in. Using hole
closest to the blade will result in a shallow cut, whereas using the hole furthest from the blade will
result in a deeper cut . The slot on the pusher bar is for a more fine tuned adjustment.
2. Assemble the plow cross tube (Ref# 15) to the front pusher bars (Ref# 14 and 17) using

bolts
and lock nuts (Ref# 12).
3. Assemble the ram mount (Ref# 1) to the main frame using the two studs that are welded to the frame and
below the front of the console. Install rod end (Ref# 7) onto cylinder with

clevis pin (Ref# 16) and
1
/
8
" bridge pin (Ref#3) mount the hydraulic cylinder (Ref# 4) to
the plow crossbar (Ref# 15). Connect the other end of the hydraulic cylinder to the ram mount (Ref# 1)
using
5

x 1½ Clevis Pin (Ref# 2) and
1
/

" bridge pin (Ref#3).
5. Slide the plow/pusher bar assembly under machine and connect to ma-
chine. Secure using ½ x 1½ clevis pins (Ref# 13) and
1
/

" bridge pins (Ref#
3).
6. Thread four, 45° elbow fittings (Ref# 18) into the single bank valve (Ref# 22),
one each in the A port, B port, IN port and OUT port. Reference Single
Bank Hydraulic Valve Drawing for a detailed view of the valve.
7. Thread two,
3
/

straight thread elbow fittings (Ref# 5) into the ports on the
hydraulic cylinder (Ref# 4). Make sure the fittings on the hydraulic cylinder
are pointing towards the machine.
8. Next connect the 43" hose (Ref# 24) to the fitting in the B port and connect
the 51.5" hose (Ref# 23) to the fitting in the A port.
9. Using the valve mount as a template, Measure in approximately 3 inches
from edge of right fender and mark. Line valve mount up with contour of the
fender and the right side of the line you just marked. Trace holes onto
fiberglass. Drill holes out.
10. Mount the single bank hydraulic Valve (Ref# 22) to the valve mount (Ref# 19)
as illustrated, using the two ¼ - 20 x 2 bolts (Ref# 20). Secure with the two ¼ - 20 flange whiz-lock nuts.
Connect the straight handle (Ref# 21) to the valve. Reference
Single Bank Hydraulic Valve Drawing for a
detailed view of the valve.
11. Route the 43" hose (Ref# 24) from the B port on the single bank hydraulic valve to the top port on the
hydraulic cylinder. Route the 51.5" hose (Ref# 23) from the A port on the single bank hydraulic valve to the
bottom port on the cylinder.
12. Disconnect the negative (-) ground battery cable from the battery. Place a drain pan under the valve on the
machine. ENGINE MUST BE COOL BEFORE DISCONNECTING THE HOSES.
13. Disconnect hose (Ref# 26) from the IN port on the two-bank hydraulic valve (Ref#25). Connect this hose
(Ref# 26) to the "P" port of the single bank valve (Ref# 22). Connect the 26" hose (Ref# 27) from the "T"
port on the single bank valve (Ref# 22) to the IN port of the two-Bank valve (Ref# 25). Fasten to the frame
using the 14½" nylon ties.
14. Reconnect the negative (-) ground battery cable to battery.
15. Make sure that everything is clear of the machine. Start the machine, work the valve so that the plow will
both raise and lower. Also, do this with both the attachment lift and the rake lift. Work the lift a number of
times until all air works out of the plow circuit and the cylinder works smoothly. At this time look for
hydraulic leaks. If there are leaks, turn engine off and repair, start up and check again.
16. Check the hydraulic oil level. The level should be 2” to 2½” below the top of the tank. If more is needed,
use SAE 10W-40 API service SG motor oil.
