WOULD NOT START

[Kelvin]

Bird,
Trivia #1: To my knowledge my older B7100 only has the clutch safety switch. I know that it'll start with the PTO engaged, range selector in any position, and gear selector in any gear.

Trivia #2: Curosity got the best of me, so I connected my newly aquired "used" Landpride Air Tunnel AT 25-60 (normally used on my B2150) up to my old B7100 just to see how it would handle it. To my surprise, it didn't appear to strain it at all. Even going up one hill the B2150 (with attached FEL) bogs a little bit but the B7100 (with attached mid-mower and rear mower) didn't.

I am still very impressed with the old B7100.

Jag, as Wen said, you'll have to make that call, but I'd see what's wrong with the switch. If it's a weak spring, you might be able to put a stronger spring on it. If it's dirty, you could clean it and perhaps put a boot on it if it happens again. I don't think I'd defeat that one, though.

Mark, on this switch there would be no way to put a boot. If one could go on why did the tractor not come with one. I do not believe that you could change springs on it. The switch is about 1/2 inch long and maybe 1/4 thick mounted flat on the transmission case. The spring is of a dog leg shape, attached to the switch case on one end, and runs along the switch body and then turns away from it. The end runs along about a 3 inch cam plate on the PTO shaft just below where it turns down vertical. To remove the switch you would have to remove the steering wheel column pedestal sheet metal and most likely the instrument panel and cover. If a replacement switch will only last as long as the first I do not want to replace it. Why should I have to change a switch every 300 hours. What I really wanted to know is does this switch go out that often. If it does I will wire in a momentary switch mounted just above the PTO lever that I could push to start the tractor, when the safety switch acts up. Since no one says they are having a problem with this, I guess I have a bad switch. But looking at the design it looks to me like it set up to fail. Thanks

Jag - My guess is that you just happened to get a lemon switch. If it's that big a pain to change, and they were going bad with any sort of regularity, there would've been a running thread discussing it already. Hopefully, if you change it, it'll be fine for forever. How old is the tractor?
