TC40D 4wd drive problem

I would say we have seen at least a half-dozen and maybe as many as a dozen.

New Holland definitely has a problem with the front ends on their tractors. I had a TS100A that I just sold at auction, after cracking 3 right front hubs and having a front differential go out on me I have had it with New Holland. I had a frontloader on my tractor and everytime I used it to do any heavy work at all a hub would crack. New Holland told me I was driving too fast when I had a load. The last time a hub cracked I never exceeded 3 MPH and was moving over flat ground. Check out these pics of my front differential that went out on me, I was pulling a small 10 foot disc when my 4WD went out. Notice the elongated holes on the one part and the eight sheared off bolts.

Start writing letters to New Holland so that they will fix these problems. I plan on buying a John Deere!!

Are your front tyres bulging at the bottom when you are carrying a load ? That looks to me too be the result of extreme axle wind up . You may need to put more air in the front tyres so that they remain as round as possible , regardless of the pressure (within reason) . I run 25-30 psi in my TL100A and carry very heavy loads .

My dealers, shop foreman, told me several years ago that NH had a problem with the ring gear and bolts. Sure does make me cringe to think of having to replace that on my tractor. And, I have put it through the paces.
