[AT] Need help with newer compact tractor

[Mike M]

So about a year ago I bought a Mahindra 4035 40 HP diesel tractor. I 
starts, runs and works fine, but I've had some problems with leaks 
lately. At the 100 hour mark Mahindra wanted me to change the hydraulic 
filter, which sits on the side of the rear housing. I talked to the 
service guy at the dealership and he said I'd lose about 2 gallons of 
fluid when I did that, even with the one rear tire up on a block. It 
holds 10 gallons overall, and TSC had their premium universal  
hydraulic/transmission fluid on sale (which states it meets or exceed 
Mahindra specs)  for $35 for 5 gallons. For me it seemed like a no 
brainer to just dump the fluid and replace it rather that trying to 
guess how much I'd lose.

Everything went fine, I had to remove a side cover as well as the filter 
to get to a screen they wanted to have cleaned on the first service 
only. After that the tractor performed as it should but after about 50 
hours I've started to develop leaks in the hydraulic system. They fixed 
one by a large square diverter valve under the tractor and today they 
are fixing another leak from the power steering block up by the steering 
wheel.  I called today and talked to the service guy and he says they 
are puzzled because the leaking o-rings they are looking at today appear 
burned, as if exposed to excessive heat. Another concern that I brought 
up to them is that the loader doesn't seem to have quite the lifting 
capacity as when it was new.

My question is, can fluid cause these type of problems? In the manual 
they call our for Mahindra fluid, Gulf Universal Tractor Transmission 
fluid, Mobil 424, Shell Donax and a few others, all of which are nearly 
impossible to find.  Can a fluid be SO wrong that it would cause 
problems? Right now they are looking at anything that might be causing a 
continual "deadheading" situation, but with that little 3 cylinder 
diesel I think I would notice that.

Any and all thoughts greatly appreciated.

Regards,

Mike M
