The AllisChalmers tractor range | Heritage Machines
The verdict. I found that the ED40 is the AllisChalmers tractor you can probably get the most new parts for. You can use engine kits that are for Ferguson FE 35 fourcylinder diesels. You can also use the wheels and tyres from the FE 35 as well, the rears are 11×28 and the fronts are /19 or /16.
