equipped with cable loops or rings.
Inspect towbar or wire tow cable before towing to ensure it is in good condition. The strength of the towbar or wire
tow cable should be at least 150 percent of the gross weight of the towing machine. This requirement is for a disabled
machine that is stuck in the mud or for towing on a grade.
