Hello all,
I'm looking for some initial troubleshooting guidance. I recently purchased a 5 ft brush hog to attach to my also recently purchased 1955 IH 300u. When I hooked it up for the first time I took it for a test spin through some tall grass and things quickly went sideways. I noticed almost immediately that the PTO stopped turning, but later realized that I hadn't fully engaged the lever to the latched position, so I think it was just slipping a bit. After stopping to see what was going on with the PTO, I notice smoke coming out from under the tractor only to figure out that the exhaust pipe was getting the tall grass hot.
I drove the tractor out of the grass and thought that the multiple crises had been averted only to realize that now the engine sounds like it is bogged down. It acts like it's under full load when it's sitting unloaded, just idling. It won't rev up and I have noticed a puff or two of smoke coming from under the hood near the exhaust manifold. The PTO engages and spins easily with no change in engine loading. When I try to drive the tractor it sounds like it's extremely loaded and almost kills it. It now starts hard and runs on after shutting the key off, which it never used to do.
I'm thinking that I'm going to have to tear the engine apart to see what's going on in there, but if anyone has had a similar experience and could point me in the most probable direction, I would appreciate it. The thing that has me confused is why the engine sounds overloaded. Any advice is appreciated.
