I have a 2014 Mahindra 6110 with 800 hours on it, that has been over heating every time I cut my grass with my 12 ft. Rhino bush hog. This problem started in the first of July this year when the plastic fan and belt broke for no reason. Right after my dealer replaced the fan and belt I started getting a Squealing sound coming from my AC compressor because the compressor was locking up. If I turned the AC on and off 3 or 4 times the Squealing sound stopped and the AC would work, BUT my tractor would over heat within 30 minutes of grass cutting with the AC on. I always ran my Tractor in Medium and the gear in number 1. I have run my tractor for the past 4 years like this with out it ever over heating. My Dealer told me to run my tractor in Low and number 1 gear till they figure out what is going on with my tractor and its over heating problem. I did as my dealer suggested and ran my tractor in Low and 1, and now it took 40 minutes this time for my tractor over heat again. I found if I run my tractor in neutral at 1700 rpm and with the pto shut off and the ac shut off that I can get the Temperature down from hot to 1/2 in 4 or 5 minutes and I can continue to cut my grass for another 10 minutes before the tractor over heats again. Now out of Frustration I tried something new. I got my tractor temperature back down to 1/2 now, and when I turned the ac on the temp immediately when to 3/4 before I shut the ac off, I did this 4 times and each time it did the same thing, it immediately when from the 1/2 to 3/4 before I would shut the ac off, because if I didn稚 shut the AC off, it go up into the hot. This all happened while my tractor was sitting in neutral. So I thought ok lets try running the tractor with the ac off. I put the tractor back in medium and number 1 in the gears, and I had to open all the windows like I have had to do many times before, but with the ac off I was able to completely cut all 6 acres of grass around my house with the temperature now just below 1/2 and no over heating. I am Sorry for the long post, but I believe my AC compressor is BAD AGAIN? If this AC compressor is bad and this is what is causing my over heating problem, This will make the THIRD AC COMPRESSOR in 4 years that had to be replaced. If any of you think my AC compressor is bad, My Question to you Is this NORMAL for Mahindra tractors to burn up the AC compressors? A new AC compressor is around $700.00 to 800.00 for the compressor alone, not counting labor to put it on. Please Help me, Is this NORMAL for Mahindra tractors to burn up the AC compressors in such a short time? I Thank you all for any help.

You did not mention the condition of the radiator. Is there a removable screen in front of it? Is is frequently cleaned when mowing? Have the radiator fins been cleaned? Can you shine a light through them?
Does the tractor have removable side panels? If so, removing while mowing should help.
It seems impossible for a bad AC compressor to cause overheating.

If your compressor is locking up, you might want to check the lines for vapor lock or something similar. Maybe bleed them?
Also you mentioned that the compressor was squealing. Did you check the tightness of the belt on the pulley? Could it be too loose?
I agree with AchingBack to check out the radiator, and I would also check the hoses for an obstruction going into and out of the block.
Just guessing here, but I think it's doubtful you're burning up 3 compressors.

I have a Mahindra 4510 with a similar problem. The core/fins on the radiator are quite close and it fills up with dirt/debris/seeds etc. I must air blow the same out after every use to keep it even reasonably cool which is much hotter than I prefer. It really ran warmer than it should until I took off one of the side panels as mentioned by AchingBack. That helped cool it down so it is at least tolerable to run, still between medium to hot, before much nearer the red hot line.
This was even after I lowered the battery for better air flow, removed the obstruction of the windshield washer container, added an electric push fan in front of the radiator. Just not the best designed cooling system if you mow in tall weeds, grasses etc.

yanmars Thank you for your reply. we have always keep the radiator and screens clean. Like I said my tractor has never had a over heating problem till now, 4 years latter and when I ran it the other day with my AC off, I was able to cut 6 acres without over heating.
Duffer Thank you for your reply. My dealer had my tractor in for this problem, I would Think they checked out all that you have said to help me. I am going to copy your reply and save it just in case I need it in the future. Thank you again for all your help.

It might be time for a new radiator, or at least a good flush.

you could have a bad thermostat or water pump.. either one of those will cause overheating. it's something to check for.
