I'm currious about your 1500 rpm statement. It seems like a lot of guys run their diesels just above idle most of the time. What I've read is it really isn't good for the engine. Now with tier 4, it is even worse leading to fowling, premature pluggin of the filters and regens depending on the manufacturers particular solution to the problem. Several makers suggest idling after startup at at least 1500 and run them above 2000. Any thoughts?
This is the beauty of Mahindra built Tier 4s. They have no DPF!
There is a great thread where towards the end I shared a bunch of the Mahindra info and people compared notes on the different manufacturers' methods to address the final emissions requirements. Check it out here:

There is no doubt in my mind that the mCRD with a DOC is the way to go in CUTs that usually are not running wide open doing endless hours of ground engagement. I am often putting around at 1500- 2000 RPM doing loader work and the 2538 behaves like a champ. When mowing or doing heavy box blading then it gets wound out to 2500 RPM +/-. Mahindra was one of the few manufacturers who spent the money to leapfrog over just bolting on a DPF to an electronically controlled engine as many other manufacturers did. Really a personal preference I guess.
I agree about the hydro whine. Worse on some than others. Question about operating if you are going to mow/brush cut do you engage the pto, ramp up the rpms and then select a gear? Is it okay to clutch at higher rpms? I've seen it done just not sure if it is good or not. Thanks for your help.
I do not have shuttle/gear experience so cannot help with the clutch question. On my machine there is no clutch, so I take the RPM down low before actuating the PTO and then roll on into it. In my opinion, the HST is very easy to operate when in tight quarters, woods, and when doing a lot of loader and
grapple work. This is basically my life, so it is the route I went. I honestly do not notice too much whine on the 2538, but certainly that could be a factor for some I suppose if you don't use PPE. If I do any lengthy mowing or need to road the machine down to the Church or neighbors, I just get up to speed and push the electronic cruise button, (it was a cheap option and a magnet actuates on forward pedal arm under deck). Then I sit back and stretch my legs!
If I were to have a hundred+ acres and be pulling plows and balers all day, then I would have gone for a bigger shuttle/gear machine, but for all around CUT use on smaller tracts, a good hydro is hard to beat for my types of needs.
Good luck!
