Overview

The Challenger 45 is a high-performance agricultural crawler tractor featuring a 240 hp Caterpillar 3116 turbocharged diesel engine and a 16-speed full power shift transmission. Built for heavy-duty farm work between 1995 and 1998, it offers versatile track options ranging from 16 to 32 inches and a substantial rear lift capacity of 12,500 lbs.

Ideal Applications

Heavy Implement Operation: With a Category III/II rear hitch capable of lifting 12,500 lbs and a high-flow 31.2 gpm hydraulic system, this tractor is well-suited for managing large, demanding implements.

High-Traction Field Work: The crawler drive system, combined with multiple track width options and a 170 hp claimed drawbar power, provides the stability and ground contact necessary for challenging soil conditions.

Extended Daily Operations: An air-conditioned cab comes standard for operator comfort, while the 125-gallon fuel tank supports long working hours without the need for frequent refueling.
