New holland tc33d tractor model 7308
Now SLOWLY raise the loader all the way up, at the end of it's lift, lower it VERY SOWLY to the ground. Start the tractor and (after it's a little warm) bring the rev's up to about 2000rpm and leave them there.

Place the machine on a flat, level surface, in a safe location to cycle the loader through the full range of it's motion. It sounds like there is a SEVERE cavitation problem in that loader, the lack of down-pressure and the 'bounce' (rolling up before dumping) is caused by a large amount of air trapped in the system.
Called my dealer and they suggested checking my quick connect couplers to see if one might be bad.Does anyone know where the pressure relief valve is located?. Does your bucket have any down force because mine don't.It was working perfectly earlier that day. The salesman said this was normal, something like a speed governor. When I went through the motions with the empty loader, (they don't let you scratch the paint on the new ones) it made all kind of weird noises. I just test drove the 29D/33D last Thursday. If it wasn’t so hot, maybe I’d get something done. If a gauge is available, pressure tests at several points in the system may shed some light on the problem. If the loader is plumbed behind the 3ph, then I’d ensure that the 3ph isn’t in lift mode and that the pressure relief valve isn’t open. If the 3ph has power, then the problem is likely in the loader SCV. If the 3ph also has little power, the problem is likely the pump, pressure relief valve or suction line/filter. I'm making an assumption here that the set up is a common one where the loader SCV outlet feeds back into the remote high-pressure line to the 3ph. If the tractor has a hydraulic manifold block/diverter valve, I'd check to make sure the diverter valve is fully in the auxiliary position. It sounds a lot like there's little pressure from the pump. And they won't give me the contact info so I can call the regional rep myself (because it isn't part of their predefined customer service process). They just call my dealer for his advice and then say that the regional representative will call me within 3-5 days (he never called). I thought about calling NH Customer Service for additional help, but the last time I contacted them, it became obvious that the people answering the phone don't know the equipment. If anyone knows of a fix, I too would appreciate the help. I took it to the dealer and the mechanic said it was a "feature" of that particular loader. Once the bucket has dumped, or any time with an empty bucket, the fast dump works fine. After loading the bucket, when I push the lever to the fast dump position, the bucket either doesn't move for several seconds or curls up very slowly for a few seconds. When you are trying to back drag, are you pushing the lever to far forward, past the detent, and into the float position ? Hope this helps you.ĭoug, I have a similar problem with the 7308 on my TC33D. I have no knowledge of a fast dump position, although it may exhist, maybe one of the other readers can help you on that one. If it is a single lever control then moving the lever either left or right would dump the bucket, the opposite direction would curl the bucket back up. All day it was working fine,when i would backscrape it would lift the front tires off the ground,now it has no pressure at all.Fluid level is ok and there is no sign of any leaks.Any help would be great.Thanksĭoug, I have never operated a 7308 loader but I would beleive that control wise the all should be very similar. This compact utility tractor could be equipped with the New Holland 7308 loader.Yesterday while working with my loader(7308)it started dumping slowly when I moved the control to the right for regular dump,and when I move it to the extreme right(which should be for fast dump)it rolls back instead.Also I have no down force for back scraping.
