i just want to know your guys opinion on this. I have a chance to buy a bobcat 743 runs ok drives well everything seams to work well. It comes with a grapple bucket a tooth bucket and pallet forks. The secound bobcat is a 743b with a blown engine. This one comes with a grapple bucket and solid rubber tires (not really good condition). The motor over heated and there was water in the oil. I think the head may be warped i am not sure. The head is off but i cant tell if it warped. Well they want 5k for everything. Is this a deal worth going after? I am i going to have a huge nightmare fixing this 743b? I have had a 743 before and worked on it but i just dont want to be in over my head with this. Antother question what is the differnece of the 743 and 743b?
