!
DANGER
Stay away from a blade that has tripped and will not reset
itself. Do not attempt to free the blade by hand as the blade
can suddenly spring back due to the high return spring load.
See “Jammed Trip Blade” instructions on page 21.
Pre-Operation Inspection
1.
Park tractor/skid steer with Trip Edge Blade on a flat
level surface. Place transmission in park, set park
brake and lower blade onto the level surface.
2.
Shut tractor/skid steer off, remove switch key, relieve
all pressure in the hydraulic lines and wait for all
moving parts to come to a complete stop before
dismounting from the tractor/skid steer.
3.
Visually check for excessive wear, worn, damaged,
cracked, or loose parts. Replace parts with genuine
Land Pride parts.
4.
Inspect all connections for leaks. Tighten any
connections that are loose.
5.
Start tractor/skid steer and check hydraulic oil leaks
with a piece of paper or cardboard. Do not use your
hands as invisible thin streams of high pressure oil
can be injected into your skin.
6.
Inspect hydraulic hose for pinch points that can
damage the hose during operation and for sufficient
length and equipment clearances. See “Equipment
Clearances” on page 10.
7.
Check all controls and operating functions of the
tractor/skid steer.
Trip Edge Blade Functions
Raising & Lowering The Trip Blade
Use tractor/skid steer arms to raise and lower the Trip
Blade. Often the arms are set to float so that the Trip
Blade can float over the terrain while riding on the skid
shoes.
Tilting the Trip Blade
Operate cylinders at the front of the tractor/skid steer
loader arms to tilt the Trip Blade forwards or backwards.
Do not tip the Trip Blade forward to apply down pressure
as this will cause the Trip Blade to ride up over the snow
and will trip the blade.
Angling the Trip Blade
Angle the Trip Blade to push product to the side by
operating the tractor/skid steer hydraulic lever. Move the
lever in one direction to push product to the left and in the
opposite direction to push product to the right. Release
the lever when the moldboard is at the preferred angle.
Switch male and female couplers on the hydraulic hoses
if lever action is opposite of what is preferred.
Pivoting the Trip Blade
Refer to Figure 4-2:
The Trip Blade is designed to float over the surface on its
skid shoes while pivoting as much as 15
o
clockwise or
counterclockwise. Lock pivot assembly with blade
straight across when transporting, working around the
machine, and when storing it. Unlock pivot assembly
when pushing product with the blade.
