B.M.B. President Tractor

The B.M.B. President Tractor above is fitted with the optional hydraulic linkage.  The unit was bolted to the side of the tractor and gearbox oil was pumped into the external rams which operated the mid-mounted tool frame and three-point linkage.  A simple depth limiting device with two metal blocks fitted to the mid-mounted tool frame and supported by the front axle controlled the working depth of cultivation implements attached to the tool frame.  Screw handles either side of the tractor were used to control working depth, the pivoting action of the front axle maintained an even depth when working on uneven ground.
