I agree with your view, yanmars.
Maybe DavesTractor can pay them a visit, and teach them how to be a GOOD dealer.
There are other dealers that would benefit from a Dave tutorial or two... or three... etc...
Glad u got it back.
The 4510 has 2 screens to keep debris out. One in front of the radiator and one behind. The one behind is almost invisible. We had problems with one and kept cleaning the front screen. It would help to keep the engine cool but the air conditioning wasn't worth a crap after an hour or so of running. Finally after some time found out about that rear screen. Problem solved and haven't had a minutes trouble since out of that machine. It really is hidden back behind there like a ninja. I figure that somebody already checked this but sounds like your symptoms are very similar. We laughed at ourselves pretty hard after hours of scratching our heads looking for problems with the cooling system. Maybe you will too. Good luck.
I would figure somebody would have already checked that myself, but ... never know. OP, is this critical heatng a problem with that model line, or as far as you know, isolated to your tractor? Have they checked your water pumps performance? Is the shop actually competent? With "nothing" wrong, and improvements on that even, what does the Mahindra rep say? ... Do your hydraulics seem normal, or do they get real hot even when not in use?I will look in back of the radiator. I do not recall seeing a screen there but will check. Thanks
