Hydraulic Hose Hook-Up
WARNING
!
To avoid serious injury or death:
Hydraulic fluid under high pressure will penetrate the skin 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. If an accident occurs, seek immediate emergency medical
care or gangrene may result. DO NOT DELAY.
Refer to Figure 1-2 on page 10:
1. Route hydraulic hoses through the most convenient
path to access your tractor couplings.
2. Clean quick disconnect couplers of dirt and then
connect male and female couplers to the tractor
outlets. Make sure quick disconnect couplers have
fully engaged. If they have not, check the following:
a. Make sure couplers are same size and type.
b. Make sure hydraulic system pressure has been
released.
3. Extend and retract hydraulic cylinder with tractor
controls. Switch male and female couplers on the
hydraulic hoses if hydraulic cylinders operate
opposite direction intended, and then reconnect
hoses to tractor outlets.
4. For additional help, refer to Hydraulic Hook-Up in
your tractor Operator’s Manual.
Equipment Clearances
Refer to Figure 1-4:
It is important to check the clearance between tractor
loader and grapple before putting grapple into service.
Make sure hoses are long enough and won’t become
pinched or entangled in the equipment. Also, make sure
the grapple does not come in contact with tractor loader.
1. Visually inspect hydraulic hoses for possible pinch
points and shortness. Make hose adjustments before
operating hydraulics to checking clearances.
2. Start tractor and raise grapple approximately
12" (31 cm) off the ground.
3. If necessary, have someone stand nearby that can
motion for the operator to stop if a problem develops
while completing steps 4-7 below.
IMPORTANT:
Make sure coupler fittings on the
hydraulic hoses and power machine are clean
before connecting them together.
IMPORTANT:
Add cylinder stops (#2) to hydraulic
cylinders (#1) if grapple or hydraulic hoses come
close to making contact with loader. Purchase two
sets of cylinder stops (#2) (Part No. 810-818C) from
your nearest Land Pride Dealer.

4. Fully extend grapple hydraulic cylinders to pivot
upper jaw (#3) fully down.
5. Fully extend and retract hydraulic cylinders (#1) on
end of loader arms while watching for interferences
between loader and grapple. Stop movement if
grapple or hoses come near the loader. When
needed, add an equal amount of cylinder stops (#2)
to both cylinder (#1) to keep grapple and hoses from
hitting or becoming entangled with the loader.
6. Fully retract grapple cylinders to pivot jaw (#3) fully
up and repeat step 5.
7.
Raise grapple fully up and repeat steps 4-6.
8. Lower grapple to ground and close grapple jaw (#3).
Purging Hydraulic System
1. With grapple raised off the ground about 12" (31 cm),
cycle grapple hydraulic cylinders several times from
fully extended to fully retracted.
Refer to Figure 1-3 on page 11:
2. If cylinder operates unevenly after cycling it several
times, then purge hydraulic system as follows:
a. Loosen hydraulic hose fittings (#2) at rod end of
hydraulic cylinders (#1).
b. Slowly retract and extend hydraulic cylinders to
purge any trapped air from the system.
c. Tighten fittings (#2) to hydraulic cylinders (#1)
once all trapped air is removed.
