Mahindra 4500 Hydraulics Overheating???

JoeGwozdz · Jul 21, 2005

Hi I was wondering if anyone has had a problem with the transmission and/or hydraulic resevoir under the seat over heating on the Mahindra 4500? I've noticed that mine has been after about a half hour of use since it was new, and it now only has about 100 hours on it... so hot you could fry an egg on it. The dealer I purchased the machine from has been no help so I'm curious to know if anyone else has had this problem.

Joe,
It would almost have to be tested to tell if it was to hot. It is quite normal for the hydraulic fluid to be 100* over ambient temperature.

A hydro tractor's hydraulic temp runs at about 180 degrees.

What type of hydraulic use are you doing? The 00 series tractors do have a small resivoir, around 3 gal I think. That's one of the reasons I got a pto pump for my backhoe. If you are doing normal loader and 3pt work I would not think this to be an issue. If you are using the aux hydraulics for a pump or log splitter or something similar it might be something to look for. There is really nothing that can be done aside from installing an air heat exchanger somewhere in the return, or an auxillary tank to increase capacity and surface area if that's possible. This was a concern of mine as well. I think when the fluid gets too hot it is supposed to foam though, so you might have visible evidence if it is indeed to hot. I'd like to wrap this up stating that I am by no means an expert so please take what I say in that light. Just trying to offer ideas for you.

The hydraulic system capacity is 3.7 gallons. Please refer to your owners manual for the appropriate oil to use depending on the air temperature when using the tractor.

The hydraulic casing does get hot as this is the way the oil temperature is reduced. The heat is transferred to the case where it is dissipated.
