C. Lower boom until parking stands contact
ground.
D. Extend bucket cylinders until cutting edge of
bucket is frimly on the ground.
E. Remove pin from mounting bracket.
G. With tractor at idle speed, roll bucket back
until subframe raises up off rear bracket.
H. With tractor at idle speed, carefully activate
boom cylinder until cross tube is free of pressure
within front bracket channel. It may be necessary to
roll bucket back further to maintain sufficient clear-
ance between subframe and rear cross tube.
I. Disconnect hydraulic hoses from tractor quick
disconnect couplers.
J. Carefully back tractor out of loader.
NOTE
When dismounting the 2427 QT from certain tractor
models, additional subframe height is required to
clear the front axle. This may be done by rotating the
subframe back by extending the boom cylinders
once the cross tube is free of the front channel.
K. Reinstall cuffs to loader subframe and place
pin in front mounting bracket for storage.
L. Clean all dirt and debris from loader. Dirt will
hold moisture and cause rust.
M. If loader is to be stored for an extended period
of time, perform lubrication per paragraph 4-2. Also
apply coat of heavy grease to exposed cylinder rods
to prevent rusting.

OPERATING INSTRUCTIONS
3-1 GENERAL SAFETY
Only qualified people familiar with this operator’s
manual should operate this machine. Operator
should wear hard hat, safety glasses, and safety
shoes. The operator should read, understand and
practice all safety messages shown on the caution,
warning and danger decals affixed to the loader to
avoid serious injury or death. It is recommended that
tractor be equipped with Rollover Protective System
(ROPS) and a seat belt be used. Check for ditches,
stumps, holes or other obstacles that could upset
tractor or damage loader. Always turn off tractor
engine, set parking brake, and lower loader to
ground before leaving tractor operator’s seat.
3-2 OPERATION
The loader should be operated with the tractor
engine running at 1200-1700 rpm. Excessive
speeds are dangerous and may cause bucket
spillage and unnecessary strain on both the trac-
tor and loader.
When operating in temperatures below 30°F (-1°C.),
run the tractor engine below 1200 rpm until the oil
temperature exceeds 30°F.
A bucket level, indicator rod (Figure 3-1) located on
the loader frame can be used to determine bucket
angle. Before beginning work, observe the position
of indicator rod with bucket flat on ground. Raise
boom to several different positions. At each position
level bucket, then observe the indicator rod. Once
familiar with the indicator rod positions, operation of
loader will be easier and more efficient.
The following text and illustrations offer suggested
loader and tractor operating techniques.
