Jammed Trip Blade
!
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 spring return load.
!
DANGER
Do not disassemble blade and springs while springs are
compressed. Each spring can store over 1000 lbs. The sudden
release of this force can cause great bodily harm.
With proper maintenance and under normal operating
conditions, the blade should always return to its
operating position after tripping. Stay away from the
blade if it has not returned. Do not pull debris from the
blade hinge or attempt to work on the blade to free a
bound area.
Penetrating oil can be sprayed on the hinge to help free
blade movement. Be sure to keep a safe distance away
from the blade’s rotational path and blade hinge while
spraying.
Try resetting the blade by lowering it to the ground and
backing up with the tractor/skid steer. Do not catch the
blade on a solid object while backing up as this can
damage the blade and blade hinge.
Perform maintenance on the blade after it has reset itself
to keep the blade from becoming jammed again. See
“Trip Hinge Maintenance” on this page for instructions.
Hydraulics
!
WARNING
Always secure the Trip Edge Blade with solid supports before
working under it. Never work under equipment supported by
hydraulics. Hydraulics can drop equipment if controls are
actuated or if a hydraulic line burst. Either situation can drop
machinery instantly even when power to the hydraulics is off.
One of the most important things you can do to prevent
hydraulic system problems is to ensure that your tractor/
skid steer's reservoir remains free of dirt and
contamination. These simple maintenances will go a
long way to prevent occurrence of hydraulic problems:
1.
Replace your tractor/skid steer’s hydraulic filter
element at the prescribed intervals.
2.
Inspect tractor/skid steer hydraulic oil level. Add oil if
it is low.
3.
Use a clean cloth to wipe hose ends before attaching
them to your tractor/skid steer.
IMPORTANT: If blade will not reset itself after
backing-up, have a qualified service technician repair
the unit. Do not attempt to repair it yourself.
4.
Inspect quick couplers, make sure they are fully
engaged. Replace couplers if they are sized wrong.
5.
Inspect hydraulic hoses and cylinder for oil leaks.
Tighten or replace components to fix leaks.
Storage
Clean, inspect, service, and make necessary repairs to
the blade when parking it for long periods and when
parking it at the end of a working season. This will help
ensure the blade is ready for field use the next time you
hook-up to it.
!
WARNING
Always secure the Trip Edge Blade with solid supports before
working under it. Never work under equipment supported by
hydraulics. Hydraulics can drop equipment if controls are
actuated or if a hydraulic line burst. Either situation can drop
machinery instantly even when power to the hydraulics is off.
1.
Remove any dirt and grease that may have
accumulated on the blade and moving parts. Scrape
off compacted dirt from the bottom of blade and then
wash surface thoroughly with a garden hose.
2.
Inspect for loose, damaged or worn parts and adjust
or replace as needed.
3.
Repaint parts where paint is worn or scratched to
prevent rust. Ask your Land Pride dealer for aerosol
touch-up paint. Paint is also available in touch-up
bottles with brush, quarts, and gallon sizes by adding
TU, QT, or GL to the end of the aerosol part number.
4.
Replace all damaged or missing decals.
5.
A coating of oil may also be applied to the lower blade
area to minimize oxidation while in storage.
6.
To protect against sizing, lubricate moving parts as
noted in “Lubrication Points” starting on page 22.
7.
Store blade on a level surface in a clean, dry place.
Inside storage will reduce maintenance and make for
a longer blade life.
8.
Follow all unhooking instructions on page 16 when
disconnecting tractor from blade.
