I was wondering how the brakes on the case is suppose to work I assumed that when you hit the brake it tightened the band around the drum and slows you down. I guess that is what happens on my tractor except for when you step on the brakes the tractor goes into reverse. I don't think that this is normal any ideas?

Also the brake drum and band setup looks pretty crappy I don't think fully functional that it would stop very good, is there another brake systems out there that is commonly retrofitted to the case?

A brake linkage must be hitting the directional/speed valve linkage somehow. The valve is down low, so something must be hitting it.

I will have to check that I didn't think that it was normal. Did you see the video Daniel I got her running like a top.

If it has heads that use washer sealed plugs, then you need Champion RH18Y...or Onan part #167-0298

I will also have to check the linkages and make sure nothing is hitting. Does anybody know if everything is working like it is suppose and band has good brake material on it if they work good, can they stop you on a hill ect.?

I think when you hit the brake it should move the handle to the nuetral postion.So if it is going in reverse then check the adjusment and as dan said make sure it is not hitting something.And yes when the brake is pushed and all things are adjusted proper it will hold on a hill just fine.

The brake is only a parking brake. As you noticed it isn't very substantial and definitely not enough to overcome the hydraulic drive system. That's why they designed it to return to neutral which is what actually stops the tractor when the brake is applied and it sounds like yours needs to be adjusted. The adjustment procedure is posted in the Yahoo Case groups files.

Ok thanks guys I will check it out it makes since now that when you apply the brakes that it has to put the drive back into neutral I would guess that it is pushing the drive too far and into reverse.

Forgot about that! Yep, just needs adjusting. Thanks for catching that cp7! But to add, this tractor has no holding valve, so the brake does have to do stopping chores at times.

Yeah my place is pretty flat but I would fell better if I get some kind of a brake in working order. Just in case!!! I'll check it out. Also wondering if anyone has ever put a different (better) kind of brake system on a case?
