Max Pull 5,190 lbs

View Full Test Data →

Overview

The Challenger MT545B is a versatile row-crop tractor powered by a Caterpillar 6.0L 6-cylinder diesel engine, delivering a tested maximum PTO power of 125.7 hp. Available with advanced transmission options like the TechStar CVT and AutoPower partial power shifts, it provides a rear lift capacity of 9,391 lbs and a standard climate-controlled cab for demanding field operations.

Ideal Applications

Row-Crop Operations: Adjustable rear tread widths up to 116.3 inches and a high-clearance 15.4-inch drawbar make this tractor well-suited for navigating between crops with precision.

Heavy Implement Management: Utilizing a 29 gpm closed center pressure flow compensating hydraulic system and a Category II/III rear hitch, this machine can efficiently handle heavy lift tasks and high-flow attachments.

High-Speed Transport: When equipped with front-axle suspension, the MT545B can reach travel speeds of 50 KPH, while optional hydraulic trailer brakes and inboard planetary final drives ensure controlled hauling performance.
