I realize this is a late post, but hopefully it might help.
I have the 2555 cab shuttle, I believe almost everything is roughly the same as the 2565, except the additional10hp - my 2555 has the upgraded cat2 pto and if I recall they both use the same engine, just tuned differently.
That said, I've had the 2555 for about 4 years and have put right around 2,000 hours on it - I know, that isn't really that much. Regardless, though, here is what I've come across during these 4 years.
Unless you really like buying hydraulic oil, one of the first things you need to do is pull out the hex screws that are in the unused hydraulic ports of the block that is by the step into the cab. Clean them off good and put a small drop of locktite on them and put them back in the block. At about 200 hrs, mine wiggled a little loose, and I lost almost all of the fluid while I was cutting hay one day.
Next, understand that the 2500 & 2600 series (25/2655 & 65) are made by TYM. I'm not saying that is a bad thing, parts were a bit easier to find during COVID. Just letting you know. One of the biggest differences between the two TYM made 55 & 65hp, the 2600 series units have the addition of an extra rear hydraulic port (2 instead of one), and the addition of pto draft control. BTW, the 2600 series was only made for 2 years (2018 - 2020), according to Tractor data.
As far as function, my 2555 does what I bought it for, primarily for cutting, tedding & raking but also for other cat1/2 implements. I use a tym 110hp for bailing and other cat3 functions.
Hydraulics, they are responsive (unless you don't catch the hex screws backing out), and for this size, right up there with the big boys of this size in regard to power/lifting capabilities. I don't believe the 2565 has/had the option for a hydrostatic transmission (or whatever it's called these days), which hasn't been a want or desire for me anyway. The shuttle shift is very responsive but does require using the clutch for all actions (unlike some power shift models that only require the clutch for gear selection, fwd & Rev can be used without using the clutch) - this can be tiresome if you have a full day of loading to do.
Creature comforts, the air/heat works very well. The lights are okay, but are better if replaced by a light bar on front & rear. Windshield wipers/washers sort of work, but a good cleaning when it's put to bed for the day is much better.
Weight, the back end feels light, I filled my rears, which seemed to help a lot. Access to maintenance items is acceptable at best. Mahindra/TYM must have figured spending another couple of bucks to allow the hood to come up another 4-5 inches wasn't worth doing. Pulling the sides is a pita.
Hopefully, this might help you as you are looking at this size tractor.
