Here is my problem guys, I am putting an engine gaurd on my gravely tractor , when I bought this machine used it did not have one on it , the 19hp Kohler had been replaced with a magnum 20 hp kohler engine. It has a hitch on the back for pulling a cart or attachments. The hitch is a factory part. But my problem is the gaurd will not fit on because the engine sticks out too far! has anyone else ran into this? Do I have to make an extension bracket or shim to make this work right? Any advice is appreciated, the simpler the better!
