Skid Pro GB2 Brush Mower Manual Rev. 11/13/2023 Page 3
ABOUT THE BRUSH MOWER ATTACHMENT
The brush mower attachment is intended for use as a brush cutting and clearing tool. The primary use of
the brush mower attachment includes land clearing, landscaping, and grounds maintenance. Use of this
equipment in any other manner is contrary to the intended use of the attachment.
ATTACHING THE BRUSH MOWER TO THE CARRIER MACHINE
NOTE: Before attempting to attach the brush mower to the carrier machine, verify that all hydraulic
couplings are compatible.
WARNING: Improper attachment to the carrier machine may cause personal injury.
CAUTION: All hydraulic connections must be clean and free of debris before making any connection.
1. Place the brush mower attachment on a level surface.
2. Position and align the carrier machine to the rear of the attachment, within proximity of the front of
carrier machine.
3. Insert and connect the carrier machine into the attachment.
4. Connect the hydraulic lines from the attachment to the carrier machine.
5. Close latches (or other locking mechanisms) to secure the attachment to the carrier machine.
6. Using the carrier machine, raise the attachment and move the attachment to ensure hydraulic lines
are clear of air and operate properly.
CAUTION: Hydraulics should operate in an even and smooth manner. Hydraulic movement that is
not even and smooth may indicate that air is in the hydraulic lines.
7. Lower the attachment to ground level.
8. Inspect that the attachment is mounted properly and securely. If the attachment does not meet this
requirement, follow the instructions to remove the brush mower and re-attach using the instructions
above.
REMOVING THE BRUSH MOWER FROM THE CARRIER MACHINE
WARNING: Improper disconnection may result personal injury or damage to the attachment and carrier
machine.
CAUTION: All hydraulic connections must be clean and free of debris before disconnection.
1. Using the carrier machine, lower the attachment to the ground.
2. To prevent contamination, remove any dirt and debris from the couplings. Disconnect the hydraulic
connection between the attachment and the carrier machine.
NOTE: Hydraulic connections must be disconnected before disengaging latches to prevent damage to the
carrier machine or the attachment.
3. Disengage the carrier machine latches (or other locking mechanisms) from the attachment.
4. Move the carrier machine from the attachment.

hydraulic lines and couplings that are under pressure.
NOTE: Shut off the carrier machine and disengage the brush mower before performing any
maintenance.
DAILY INSPECTION
Inspect the brush mower by performing a walk around daily before and after use. Use the following
inspection checklist as a guideline.
After the brush mower has been attached, check that all latches or locks are closed.
Check that all hydraulic fittings are tight and free of leaks.
Check sight glass on direct drive to ensure presence of oil. If needed, add 80/90 weight gear
oil. If oil is not present or very low, check drive train for leaks.

Check all hardware connections to the carrier machine for damage or fatigue such as cracks
or other structural flaws.
Inspect the safety chain for damage.
Inspect blades and bolts for wear or damage.
Inspect all drive train bolts (motor, mount, housing and blade) for loosening. Tighten as needed.
Check for wire or debris under the deck, remove any present.
Clean debris from the motor area.
Check that all guards and safety equipment are in good condition.
WEEKLY INSPECTION
Check blade bolts for correct torque (500 foot/pounds).
Check all bolts for tightness.
Inspect the deck for cracks, bends, or damage.
Inspect discharge chains and replace any missing or broken chains.
MONTHLY INSPECTION
Inspect the entire drive system, including motor and bearing housing.
Inspect the blades for cracks, bends, or excessive wear.
