OPERATION
Break-in Period
The windrower is ready for normal operation. However there are several items to check and watch out for
during the first 100 hours, as follows:
ENGINE BREAK-IN:
1. Operate engine at moderate load, avoid extremely heavy or light loading for longer than 5 minutes.
2. Avoid unnecessary idling. If engine will be idling for longer than 5 minutes after reaching operating
temperature, turn key OFF to stop engine.
3. Check engine oil level frequently. Watch for any signs of leakage. If oil must be added, use oil specified
under "Fuels, Fluids and Lubricants" in Maintenance/Service section.
NOTE: During the break-in period, a higher than usual oil consumption should be considered normal.
NOTE: If windrower must be driven in cold weather (below freezing), let engine idle for 3 minutes, then
operate at moderate speed until oil has warmed up.
4. Watch coolant gauge in cab for temperature rising beyond normal operating range. Check that coolant
level at reserve tank (mounted next to radiator) stays between HOT and COLD marks on tank. If over-
heating problems occur, check for coolant leaks. See "Cooling System" in Maintenance/Service section.
5. Change engine oil and filter after the first 50 hours and every 500 hours or at least once per season
thereafter. See "Engine" in Maintenance/Service section.
WINDROWER BREAK-IN:
1. Until you become familiar with the sound and feel of your new windrower, be extra alert and attentive.
2. Check A/C compressor belt after 5 hours operation for initial stretch. Tighten as necessary. (See
Maintenance/Service section). Continue to check the belt periodically for the first 50 hours.
3. Check drive wheel bolt torque according to the following schedule:
• Every 15 minutes on the road or 60 minutes in the field until torque stabilizes, then
• Daily (10 hours) until no change is recorded for 3 consecutive days (30 hours), then
• Every 200 hours or annually thereafter.
Torque specification for drive wheels: 180 ft.lbs. (245 N.m).
Torque in numbered sequence shown and repeat sequence three times.
4. Check caster wheel bolt torque after the first 5 hours and every 200 hours or annually thereafter.
Torque specification for caster wheels: 100 ft. lbs. (135 N
⋅m)
NOTE: To avoid damage to wheel disks, do not over-tighten wheel nuts.
5. Replace both hydraulic oil filters after the first 10
hours and every 300 hours thereafter. See
"Hydraulic System" in Maintenance/Service
section.
6. Change power hub oil after the first 50 hours and
every 2000 hours (or annually) thereafter. See
Maintenance/Service section.
7. Change bevel gearbox oil after the first 50 hours
and every 200 hours (or annually) thereafter. See
Maintenance/Service section.
8. Re-torque four walking beam pivot bolts (B) after
the first 50 hours. Tighten to 265 ft. lbs. (360
N·m.)
NOTE: For units with optional “behind-frame”
weight package as shown, tighten hardware to
350 ft. lbs. (470 N·m.)
