Tractor Hook-Up
CAUTION
!
To prevent serious injury:
Do not stand between tractor and attachment during hook-up.
1.
Make sure hydraulic hoses do not interfere with hitch
hook-up.
2. Drive tractor slowly to the blade making sure the front
hitch plate of the tractor is parallel with the blade
hitch plate.
3. Tilt top of the loader hitch plate slightly forward and
position top of hitch plate under the top angled bar on
the Snow Trip Blade hitch plate.
4. Slowly lift loader hitch until the top angle bar and
loader hitch have come together.
5. Push lock handles on the loader hitch down into
locked position. Check to make sure that the lock
pins go through the bottom slots of the Snow Trip
Blade hitch plate.

WARNING
!
To prevent serious injury or death:
Hydraulic fluid under high pressure can penetrate the skin
and/or eyes causing a serious injury. Wear protective gloves
and safety glasses or goggles when working with hydraulic
systems. Use a piece of cardboard or wood rather than hands
when searching for leaks. A doctor familiar with this type of
injury must treat the injury within a few hours or gangrene

IMPORTANT:
Make sure coupler fittings on
hydraulic hoses and tractor are clean before
connecting them together.
1.
Route hydraulic hoses through the most convenient
path to access your power equipment couplings.
2. Clean quick connect couplers of dirt and then
connect couplers to the tractor remote outlets. Make
sure quick connect couplers have fully engaged. If
they have not, check the following:
a. Make sure couplers are same size and type.
b. Make sure hydraulic pressure has been released.
3. Extend and retract hydraulic cylinder with tractor
controls. Switch hoses on tractor remote outlets if the
Snow Trip Blade angles the opposite direction
intended.
4. For additional help, refer to hydraulic hook-up in your
tractor Operator’s Manual.
Equipment Clearances
It is important to check clearance before putting unit into
operation. Make sure hoses are long enough and won’t
become pinched or entangled in the equipment. Also,
make sure the Snow Trip Blade moldboard does not
come in contact with tractor frame and tires by carefully
going through its full range of motions.
1.
Visually inspect hydraulic hoses for possible pinch
points and shortness. Make hose adjustments before
starting the machine.
2. Start tractor and raise blade off the ground
approximately 12". If necessary, have someone
stand nearby that can motion to the operator to stop
if a problem develops.
3. Fully extend blade cylinder to angle blade left and
then fully extend and retract hydraulic cylinders on
end of loader arms while watching for interferences
with hydraulic hoses and blade.
4. Fully retract blade cylinder and then fully extend and
retract hydraulic cylinders on end of loader arms
while watching for interferences with hydraulic hoses
and blade.
5. Raise blade fully up and repeat steps 3 & 4 above.
Purging Hydraulic System
1.
With blade raised off the ground about 12", cycle
hydraulic cylinders several times from fully extended
to fully retracted.
2. If cylinder operates unevenly after cycling it several
times, then purge the system as follows:
a. Loosen hydraulic hose fittings at the rod end of
the hydraulic cylinders.
b. Slowly retract and extend the cylinders to purge
any trapped air from the system.
c. Tighten fittings when trapped air is removed.
IMPORTANT:
The hydraulic cylinder and/or hoses
can contain air and should be purged before use.
Not purging the cylinder and hoses of air can cause
uneven jerky cylinder movement.
