I have a newly acquired Jubilee the has a large Shawnee front end loader. I will be using the tractor for mowing mostly in the summer and would like to remove it. It looks like there is a pin in a sleeve that is bolted to the axle that accepts the frame of the loader and an area at the front of the tractor that accepts the loader. My question is, the hydraulics pump for the loader assembly is connected to the front of the tractor. My guess is the engine crank. How do you disconnect that in order to remove the whole loader assembly?
