I'll keep it short and sweet. The tractor I've been driving for the past year has had a lot of issues. Which is expected sometimes, however I always have the same malfunction on the tractor. It will go to outside service to be "fixed", it will run for about 3 weeks then same thing. It literally shuts off while I'm going down the road, I lose power steering, harder to push the breaks and acceleration is gone as a result. The first two times it happened it didn't bother me, but it's the fifth time it's happened, and sooner or later I feel like it may happen while I'm in a dangerous situation. The mechanics keep saying they fix it and it keeps happening and I'm to the point now where I can't believe them. Can I refuse driving this tractor due to safety reasons even if the mechanic says it's road worthy? I have a family to think about and I don't want to get into an accident because of this. I hate complaining about equipment because I know things happen but it's actually starting to worry me.
