Agree with all comments above. Like TechGuyTN, I added cruise to my recent 2538 purchase and also swapped in the suspension seat from a 2540. That was a life saver as our tract north of town is raw and rough. You might consider that swap as well. I was upgrading from an original Max 25 which is the smaller "real tractor" that Mahindra came out with in 2012. That was perfect for 2 acres and I think would have made a really fine landscape tractor as well, especially if you were worried about weight. I needed to upgrade in size and weight for the larger acreage, but when it is wet in town, my lawn does yield somewhat to the bigger tractor, but folks don't even mow with zero turns when wet, so not a big deal. No problems when dry though, and even the Max would leave it's mark after heavy rains.
CAUTION - I was helping a neighbor move a big 800# +/- palm tree into his yard with the Max when it seemed dry after there was a hard rain the week prior. We found a wet spot in the yard and under full load I did end up making a little bit of a mess... It was still worth it for him to get the tree into the yard, but these are real tractors and can leave their mark in certain circumstances.
The price you quote for the 2538 TLB with cutter and tiller seems a tad high at least for TX pricing, but I honestly did not quote a backhoe, so I'm just speculating that a backhoe shouldn't cost $9-10 grand. (Maybe it does...)
It really is worth getting on and driving. Turn in circles on all machines as you may be working in tight quarters. I am impressed with the tight turning radius of the 2538. Lastly - the 1538 is more comparable to the 2538 than is the 1533, so keep that in mind if you want to run the 6' cutter like TechGuy TN pointed out.
Here is the nimble and stout Max 25. (Really a good unit for yard work and moving mulch around - also cut some nasty stuff with the 4' cutter.)

And the 2538 with similar equipment - It definitely is bigger and heavier, but still agile enough to work in my wooded 2 acre town yard while having the muscle for dealing with a larger recently logged tract out in the country too. (Also, they both can each fit inside a 12' x 16' barn shed with 4' walls - one at a time of course...) You just need to make sure you have a 7' wide door(s) for the 66" bucket on the 2538.

Good luck with your decision!
