 Parking brake problem

I have a two year old TC45D with an ongoing safety problem. After setting the parking brake, it will disengage when pressure is applied to the foot platform (as in stepping off the tractor!). This happened so often that I have stopped relying on the brake. Anyone else experienced this problem? I have not contacted NH yet, but I will.

Thanks for you comments - Mark in VA

 Parking brake problem

it sounds like the ratchet and the rack on the pedel might be out of alingment.when you step off you put pressure on one side and it slips off.look under the floor board to see if everthing is square.good luck

 Parking brake problem

Mark, my 2 year old TC40D had the same problem. NH is aware of it and will replace some of the parts. However, that did not fix mine. Further investigation revealed that the problem was in the small rectangular piece that the ratchet portion is attached to. It is a flat piece of steel about 1 inch by 2 inches and is welded to the underside of the floorboards. The ratchet mechanism is bolted to it by two bolts. The problem was that the weld which was supposed to hold the small piece of steel was nearly all on the floorboards, and very little of it was on the piece itself. This allowed that small piece to bend to the side, which allowed the sawtooth piece to move to the side, thereby slipping off of the end of the part of the brake pedal which it engages. That is why the brakes just pop off for no reason.
The weld was so bad that I was able to break that small, flat rectangular piece loose with just a thumb and forefinger, and about 5 or 6 wiggles. Once I had it off, I welded a short piece of small angle iron to it at a 90 degree angle, and then welded the new assembly back up to the floorboards. The T-shape allows absolutely no side to side movement, and the brakes haven't disengaged since.
To check yours for the same problem, block the wheels so that the tractor can't move and disengage the parking brake. Crawl under it and grab the gold colored ratchet (sawtooth looking) piece and see if it moves side to side easily. If it does, the weld is probably bad, ie the welder missed the joint and put the weld almost entirely on one piece or the other, but not both. I welded production in a factory for a couple of years and can see how a bunch of bad floorboard pieces could have gotten out if the jig for that part didn't allow a good shot at the weld.
The piece I added is about 3 inches long, and points out to the left at a 90 off of the original piece. Just be sure that you center it so that you can get the two bolts back in. Good luck and I hope this helps.
