Factory Direct Tractors
Running-in
3-2
4. If a front end loader is fitted, drive the tractor to
a safe level position and operate the lift, crowd
and bucket rams through their full range of
movement for at least 12 cycles.
3.3 Run-in tractor - loaded
1. Running-in the loaded hydraulic linkage
system should be done before running-in the
transmission system. Fit a slasher to the linkage
system, (don’t fit the P.T.O. shaft) fully lift and
lower the slasher as least 20 times while the
engine is working at the rated speed.
2. When operating the tractor with a load during
the running-in period, the load must be added
gradually and gears changed sequentially from
low to high. The engine should not be left at
idle for long periods. A slasher can be used
to ‘load’ the engine. Use a higher gear than
normal when cutting grass to load the engine,
making it work hard. Keep the revs up high to
stop it from stalling while working the tractor at
the same time. Carry this out for approximately
2 – 3 minutes then return to normal operation.
Alternate normal and ‘loaded’ operation for a
period of 45 minutes, then use the tractor as
normal.
3. If the above running-in condition can’t be
achieved, then light-load operation can be used
as a substitute. For example, pulling a light
implement for shallow-tillage or towing a skid
(log or heavy harrow) to provide light resistance.
Alternatively a trailer loaded with 1.5 ton of
cargo may also be used to provide a load on
the tractor.
Points for attention:
• Don’t operate the tractor at full speed for the
first 100 hours.
• Vary the engine speed often and don’t run the
engine at speeds faster than necessary.
•
Warm the engine up fully, before putting the
tractor to work.
•
Don’t start quickly or apply the brakes suddenly.
• Don’t operate the tractor at fast speeds. Slow
down to a suitable speed on rough roads or
paddocks.
• Keep an eye on the operation of all parts and
assemblies at every stage of the run-in process.
If any abnormal condition occurs during the run-
in period, adjust or repair it immediately.
