BREAK-IN PERIODS
BREAK-IN PERIOD
The first 50 hours of operation are the most
critical for insuring long and dependable
tractor life. Do the following:
1. Review the tractor Predelivery Checklist
contained in the assembly manual with your
dealer. Be sure all applicable items on the
sheet have been checked.
2. Check all fluid levels and be sure all systems
are filled with the correct fluids for your
operating conditions.
3. Check the engine, transmission, and
hydraulic oil levels hourly during the first 10
hours of operation.
4. Inspect the tractor for leaks hourly during the
first 10 hours of operation.
5. Torque the tie rods and wheel bolts after the
first hour of operation and every 50 hours
thereafter. Torque the tie rods to 300 N⋅m
(220 ft. lbs.), jam nuts to 320 N⋅m (235 ft.
lbs.), and wheel bolts to 715 N⋅m (525 ft. lbs.).
6. Operate the engine at 3/4 load as much as
possible during the first 50 hours (3/4 load is
approximately one gear lower than would be
normally used to pull a matched load).
7. Do not operate the engine at idle speed or
maximum horsepower for more than 5
minutes at a time for the first 50 hours.
8. Check the frame pivot pin, drag link and
steering cylinder cap screw torques after the
first 10 hours of operation. Torque the frame
pivot pin to 1365 N⋅m (1000 ft. lbs.) and the
remaining pins to 175 N⋅m (130 ft. lbs).
9. Have your dealer complete the “First
50-Hour Service” checklist at the end of this
manual.
