I just broke a fitting at the bottom of the tranny on my JD 4200 SST (right where the tranny filter goes in). This is the second time this year that I've broken the same dang fitting and dumped 6.5 gallons of hydraulic oil all over the ground. The first time I hit a sharp rock with it. This time I was clearing some heavy brush.
Has anyone else had this problem? It seems like a design flaw to me. Any suggestions?
Thanks,
Doug

That isn't a good think to happen once, and I suppose you'd expect things like fittings to be protected.
It's not very helpful, but in defense of the designers I'd say the design probably was driven by mechanical rather than operational issues. Despite all the things tractors have become, the origin is still a general purpose mobile power source intended for use primarily in agricultural fields. So, if there's a good mechanical reason for putting a fitting on the bottom of a TX then that reason probably outweighs problems from the lower ground clearance that results.
In terms of solutions, I'd say go slow and carry the loader low. The risk of fast ground speeds is that then the loader gets broken rather than a fitting. An improvised brush guard might help but it's important that a brush guard be of lighter construction than anything important that it's attached to. It the tractor has turf tires, converting to ag’s probably would increase the ground clearance a bit.
I know, none of this is very helpful. I'm not sure what work the tractor is doing in rough terrain, but one of the weasel type work ATV's might be a better choice than a general purpose compact tractor. At least with an ATV it should be designed for operation in rough terrain, and there'd be cause for all sorts of serious complaints if something similar happened.

At this point I would be building some type of skid plate to cover that fitting. There is nothing worse than having hat type of problem. I know I hate working in oil and to be underneath a tractor dripping with oil is not my idea of fun. As a dealer we do often get to help or build different guards for equipment when the uses get to extremes. Just make sure that you are adding it to an area that can support it properly and than watch it to make sure that you don't have build-up of material on it which might cause it to overheat the transmission. ....

This may sound totally off the wall, but the marine industry provides remote filter mounts for easy access. If you are using the machine as more dozer than tractor, it might be possible to relocate the filter. I would check with JD, companies such as NH offer tractors set up to brush cut in rough terrain and already have mechanisms in place to avoid this type of damage and I would think JD does as well. You may well be looking at a bolt on fix from the manufacturer. ....

I believe that Deere has an armor kit for this tractor, which includes a belly pan for protection. Might be worth looking into it. When I moved from a Deere 420 Utility tractor (two-cylinder) to the CUT Deere 4300, I was (and am still) concerned with brush taking out some of the exposed underside things. The old 420 was void of any wires, or hydraulic hoses under the belly.
I have noticed the new series (4x10's) have a better arrangement, but expect the underside armor is still the best way to go. I found long ago that going into brush (forward) and not backing up was the best manuever. But sometimes backing up is necessary, and &%$@ happens then. ....

Sounds like good news that JD engineers may have anticipated the problem and provided a factory fix. The cost may not be all that great of news but often the time and aggravation of constructing home-grown solutions make factory parts seem cheap--factory parts shouldn't void warranty coverage either. ....
