OPERATION ! The towing machine should normally be of the same class as the machine being towed. Check that the towing machine has ample braking power, weight, and rim pull to allow it to control both machines while on a slope. ! When towing the machine downhill, use a larger machine for towing to provide ample rim pull and braking power, or connect another machine to the rear of the machine being towed, in order to prevent either machine from loosing control and turning over. ! Towing may be carried out under many different conditions, therefore it is impossible to determine beforehand all the requirements for towing.
Towing on flat horizontal roads will require minimum rim pull, while towing on slopes or uneven road surfaces will require maximum rimpull. 2-69
