RE: (ET) Seat Switch

["Hazen, Dwight L" <hazen indiana edu>]

Lee,

Yes that has happened to me also. Then I figured out the seat switch was
worn out. It had a dead spot in it. The switch is a long travel type and it
should make contact all the time except when fully out. You can increase 
the
bounce travel by putting some tape under the seat switch contact point. 

 Brake upgrade is a good idea also!

 From Lee:

There's another side to the seat safety switch story.

If:
1. You don't have a brake update on your tractor and therefore not much 
brakes, and
2. You are going down a rather rough trail on a hillside, and
3. You bounce just enough to kill the braking power of the engine, then
4. You're going to have one wild ride down that hill.

Been there, done that!  It wasn't my idea of Big Fun!
