5.2 Connecting to the Mini Skid Steer
The LXG210S grapple is equipped with a quick attach plate, that
is designed to work with the following mini skid steer brands:
• Toro
• Vermeer
• Ramrod
• Boxer
• Ditch Witch
The LXG210SB grapple is equipped with a quick attach plate
that is designed to work with Bobcat mini skid steers.
See the mini skid steer manufacturer's documentation for
specific instructions on hitch-plate mounting.
1. Clear the area of bystanders.
2. Make sure that there is enough room and clearance to
safely drive the mini skid steer to the grapple, and that the
mini skid steer is square to the grapple.
3. Lift the latch arms on the quick-attach hitch and make sure
that the latch pins are retracted.
4. Tilt the hitch forward until the top edge of the hitch is below
the flange on the rear of the grapple plate and centered
between the vertical plates.
5. At the slowest speed possible, drive the mini skid steer
forward to the grapple plate.
6. Tilt the mini skid steer hitch back to engage the flange on
the grapple plate.
7. Turn off the mini skid steer, apply the parking brake, and
then dismount to inspect the pin alignment.
8. Push the latch arms fully down to extend the latch pins
through the grapple plate latch-pin mount and secure
the grapple. Make sure that the hitch and latch pins are
correctly engaged and secure.
9. Connect the hydraulic lines.
5.3 Hydraulic Connection
Requirements
The grapple requires one remote pressure and one return
hydraulic connection.
Set Flow Rate and Relief Pressure
• Set oil flow rate at 5.3 US gpm (20 Lpm) .
• Set relief pressure at 3000 psi (207 bar)
Check and adjust both grapple circuits so they are within the
specification.
IMPORTANT! After installation is complete, cycle grapple
then check the mini skid steer hydraulic oil level.
5.4 Grapple Removal
1. Select an area to store the grapple that is dry, level and free
of debris, away from human activity.
2. Open the grapple forks for maximum stability. Set it down
on wood planks to keep it off the ground. Make sure the
grapple is stable.
WARNING!
Risk of serious injury from escaping high-
pressure oil. Actuate controls after engine
shut down to relieve trapped pressure before
loosening hydraulic connections.
W080
3. Shut down the mini skid steer engine. Actuate hydraulic
controls to relieve any trapped pressure in the circuit.
Disconnect the hydraulic hoses from the grapple and cap
the lines to prevent dirt from getting into the couplers.
4. Tilt the mini skid steer hitch forward to disengage the flange
on the grapple plate.
5. Push the latch arms fully up to retract the latch pins from
the grapple plate latch-pin mount and release the grapple.
6. Move the mini skid steer away from the grapple.
