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 main thing it would run warm after about 40 minutes even at idle. They put in all new belts, hoses, antifreeze, thermostat and blew out the radiator debris with air from between the fins. It still ran warm. It was checked for a head gasket leak with a sniffer. No internal or external leak. It still ran warm. They added an aftermarket push electrical fan. To mount it they removed the condenser in front of the radiator and found even after repeated air cleaning that dirt was trapped and hidden behind the AC condenser.
It now runs in the mid range. The problem is that if you just ran it in a clean enviornment there is sufficient cooling but with its design if you mow in any tall weeds the seeds and chaft clog it up quickly and it is difficult to keep clean. I added a furnace filter in front of the tractor to try to catch dirt before it gets to the radiator.
The other issue was the AC itself. They added some charge and dye and could not find a leak but it just does not seem to have the capacity to do the job. It was almost unbearable and today was only in the high 70s. When it gets really hot I just remove the doors.
Mahindra may make some fine tractors but I do not think the 4510 is one of them.

Sounds like the cooling system is to small. Like my 454 Chevelle I had to go woth a 4 core radiator, a flex fan, a 160% thermostat and a fan shield.

Yanmars, I don't know if this will help but. In the past I have run across new thermostates that were bad out of the box. Drop in simmering water to test, if they open they are good. As a last resort have you tried pulling the thermostate and seeing if it runs cooler?

Thanks madmax, but remember that it is always easier to give free advice from a keyboard then to actually fix the machine....we run into our challenges as well. But It seems like they took a 2 day job that could have taken a week or 10 days because of parts perhaps and just let it sit. Seems the customer is reasonable and not hard to get along with. Also seems the tractor is not truly fixed yet. I'm not sure the radiator fin spacing issue is solvable without changing radiator cores or somehow capturing the small stuff before it gets to the radiator.
For years I mowed my orchard with an old Ford 5000. It had wide fin spacing in the radiator and stuff just went right through it. I mowed for years without issues with just the occasional air gun blowout to the fins to make me feel better. But on many modern radiators they clog quickly. I understand that the close tube/fin spacing is really efficient at dissipating heat, but only so if air can get through. Great on a car, no so much on a tractor. Just my thoughts.

Wow it looks like a POOR DESIGN. One big friggen radiator might help and then again it may not, if your not pushing enough coolant through the system. Sorry to hear about your tractor.

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?

Was it that back screen YanMars?
I have now attached an electric fan in front of the condensor. The tractor is running much cooler now although the temperatures have only been in the 70s. The electric fan is on a toggle switch and I have really not needed it now but it is available.
Hopefully this is not a duplicate post but an answer to Mahindra Don. I could not find a screen behind the radiator. Perhaps it was removed before I bought the machine. I have to admit I do not understand the function of a screen behind the radiator, the airflow is from the front to the back so I am missing what purpose the screen would have in this position.
If you could direct me to specifically where the screen is etc. I will look again. Thanks
