Underbody of vehicle (rear of tractor)
Frame: Check for cracks or bends in longitudinal
frame members. Make sure there are no loose,
cracked, bent, broken or missing
crossmembers or crossmember fasteners.
Maintain adequate clearance between all parts of the exhaust
system and all hoses, wires and lines for engine cooling, brake
system, fuel system, power steering system and electrical system, Heat
damage to hoses, wires or lines may cause vehicle malfunction that
could result in property damage, personal injury or death.

Air/Electric lines: Make sure that air hoses are not cut, cracked,
chafed or worn (steel braid should not show
through). Listen for audible air leaks, Make
sure air and electrical lines are not tangled,
crimped or pinched or being dragged against
any truck/tractor parts. Electrical line
insulation should not be cut, cracked, chafed
or worn. None of the air or electrical line
should be spliced or taped. Check for
corrosion on pins and in electrical sockets to
ensure continuity and reduced heat build-up
potential.
Deck plate: Make sure deck plate is clean, securely bolted
to the tractor frame and clear of loose objects.
Lights, reflectors: Make sure reflectors are clean and none are
missing or broken. Check for proper color (red
