these guys have the operator,service and part anuals for most tractors. they are not cheap, but for your repair and future repairs will be possible.
the service manual is about the same as the dealer has and the dealer service technician should read and understand.
for my ford tractor, i spent over $400.00. The service manual diagnostic test and problems flow charts to direct you to the problem (most of the time).
Most important, you gain the knowledge to protect yourself. At least, you can tell if the tech knows what he is doing. Some of the guys are 90 day wonders that may know have knowledge of you particular model.
Farm Tech Tractors, Mahindra, Jima, and some Massey, Case are the same tractor with different paint and body style changes. I would buy one. But you need a dealer or technician with the books and experience in the newer tractors. If I buy new tractor, i will stick with the basics and way from the fancy stuff. There are onboard computers, selinoids, and hydralics that mess up and cost a forturne to repair. New Holland, John Deere, Case, Massey all are the same. I have a 16x16 electro hydralic transmission which is this way, and I am not satisfied the dealer knows what he is talking about after reading the service manual. I found an X shop foreman that I believe can fix the problem. At least, he knows the transmission.
Summary, if you transmission is a simple one with a regular clutch, pressure plate, like the old tractors, with the service manual, basic mechanics, a clean area with a hard floor, and a tractor splitting rig, you can "get her done". The service manual for my tractor, gave the detailed drawing for the transmission stand. which allows you to work on it horizontally, and veritically. This is not rocket science. If you can read with basic mechanic skills. you can do it
any help would be great.
