Drawbar Pull is the same as rimpull, but for tracked machines.

Drawbar Pull is the same as rimpull, but for tracked machines.

• A. The maximum horizontal force a machine can exert on level ground
• B. The resistance created by the ground when moving
• C. The same as rimpull, but for tracked machines
• D. The usable pulling force of the drive tires

Answer: (C)

The pulling capability you’re measuring is the force available to move a load via the drawbar, which depends on engine torque, transmission, and traction at the ground. For tracked machines, that same limit is described by rimpull, representing the maximum tractive effort the tracks can develop against the ground when the engine is delivering power without slipping. So drawbar pull and rimpull describe the same pulling capacity, just using different terminology for tracked vehicles. The idea is about how much forward force the machine can apply to a load, given its power and how well the ground can grip the tracks.
