AXLES, TIRES, and TRACKS Liquid Fertilizer Applicator A10 / A13 / A18 / A24 Page 42
Track systems’ break-in takes place during the first season of use. Correct break-in helps reduce
amount of initial drive lug wear. During break-in, drive lugs and idlers undergo a “polishing in”
process which:
• Scours out excess rubber flash inside the drive wheels.
• Embeds fine dust particles in rubber surfaces to remove tackiness of new rubber.
Surface polishing reduces frictional heating in the track system. During break-in, new rubber
surfaces require contact with a dry lubricant such as soil. Avoid high speed operation (roading or
higher speed tillage) where the track system is run in absence of dust generated by dry soil
contact (wet conditions or paved roads). Operating in these conditions for lengthy periods may
cause excessive early-hour drive lug wear.
Perform initial break-in and alignment before any high-speed tractor operation. Excessively clean
frictional track components (belts, drive wheels, front idlers, and mid-rollers) can generate
significant heat if run unlubricated. This heat is capable of damaging components. Break-in and
align new components as outlined.
Initial Break-In
Avoid track and track system component damage. Before driving the tractor on-road for the first
time, precondition tracks with loose soil or clay-based lubricant. Repeat application of lubricant or
soil at least every 50 miles until destination is reached.
After installation of new or cleaned track belts or other frictional components, expose clean
components to materials to lubricate and break them in.
• Work the Applicator in-field in loose soil for at least 15 minutes.
• If the Applicator cannot be exposed to loose soil, use a “clay-based” granular material
(clay-based lubricant, kitty litter, oil-dry absorbent, or talc powder) to introduce a “joint”
area between drive wheels and belts continuously for at least 15 minutes.
Track Belt Alignment
After the initial break-in procedure is completed, align the track. See Check Track Alignment.
After Break-In
After the initial 100-hour break-in and alignment, a long-term break-in process (up to 400 hours)
will likely occur. During this period, maximize the exposure of tracks to soft soil and minimize high
speed, heavily loaded transport operation.
