When Case IH introduced the 99kW/135hp MX135 back in 1997, most overlooked the fact that it was broadly based upon the proven mechanicals of the outgoing ‘square-jawed’ 132hp Maxxum Pro 5150. As it turned out, the MX sold well, right up until it ceased production late last year, and today makes a strong case for itself as a used buy. James de Havilland digs deeper

From its introduction in February 1997, right up until the end of its production run in November 2002, the Case IH MX135 saw little in the way of major design changes and development. Even early MX models have no real danger points of which to be wary, a big advantage from the reliability standpoint and a comfort to those seeking older examples.

Although the MX135 looked like a completely new tractor, the fact that the model shared its drivetrain, pto, axles and its engine with the 5150 unit that it, within the Case line, took over from, can largely be thanked for its dependability, the 5150 being trouble-free in the main.

With the notable exception of front suspension from June 1998, there are only odd detail specification differences between model years. All of the units feature a four-speed powershift transmission with creep speeds to provide 32F/24R speeds air conditioning, front ballast, three external valves, Dromone hydraulic push-back pick-up hitch as well as headland management.
