So my tractor is a 1986 Ford LGT-18H w/ 48" deck that was bought new by my grandfather. He never had any problems with it until about 3 years ago when he accidentally dropped a screw and washer down the top of the engine. So he gave it too me, and ever since then it has been causeing me problems (I have taken the Magnum engine apart three times). I just graduated from High School and will be heading to college, but the good thing is that I work at a sales and service place for Ventrac, Steiner, Gravely, Grasshopper, Echo, RedMax, and others. The current problem now is that the governor has some issues, among others (including a seal in the transmission). One of my co-workers and I went through what needs to happen on the unit and decided on a high end (to play it safe) of $500. My parents were not too happy, and now they want to fix it just enough so we can get some money out of it. What do you guys think? It was a great tractor before, and I have heard the engines are wonderful. But I mean, even I don't want to put $500 bucks into something that old. Suggestions?
