what engines will interchange in a older massy ferguson backhoe
You need to post what model, year, current engine, and possibly a serial number for anyone here to be able to help you.
Most likely a Perkins that can be found in ** farm tractors. Need to know model of backhoe. Might be better to fix the engine you have though.
Probably none, if they're a rigid case setup from engine to axle..
I don't think Massey ever got past dressing up a farm tractor to make a backhoe except some stuff they imported from England. Most likely a Perkins and should be pretty easy to fix what you have.
