The loader you are talking about was bolted up to the bell housing , and back to the back axle at each side . Looking in from the side the framework looked like a flat A . The hinge point for the loader Arms would have been 6 " lower than an MF 40 loader , and possibly 8 or 9 inches forward of the front of the back tyres. Hence you had to climb over the bracket part to get on the tractor.
They were grey , so were Ferguson , and before MF .
I have no idea of model number . 732 ? What machine was that ? Finger bar mower ?
