This model was originally designed by Frenchman Pierre Monsallut and a Modelplan appeared in the July 1995 issue of the Meccano Newmag (issue 72). Since then, various modifications have been made, notably to the rear mudguards, the transmission system and the steering gear.
The transmission system from the 6-speed motor motor (see underside view), has a novel differential gear in it. Briefly, this consists of a four hole collar fixed to that shaft with two freely rotating contrates which drive pinions. These then transfer drive to two 57-toothed gears to each rear axle. This makes the model operate particularly well.
The model is said to represent a 1970–80s Ford tractor before roll over cages and cabs became mandatory.
