I have thought of pricing out loaders for my tractor and they are more money than I paid for the tractor itself. My primary concern was whether or not those loaders were either too big, or too small for my tractor. I think that the TL21 loader from a B21 tractor would likely fit right on my L245DT. However, I can get my hands on the older Massey loader for like $500, and the Kubota loader is at least 3 times that. But, if the Massey loader is going to be too big then im concerned I will damage the tractor. It should be noted however that the Massey loader has its own pump.
On another note my fabrication skills are quite "minimal". Im not afraid to try anything. However my lack of experience is one reason I am looking for a loader that is the right fit in hopes that the only mods that need to be done would be for frame mounting.
