Have you confirmed it's the low pressure switch?
Does bypassing the low switch allow it to work?
Edited to add;
if you have to replace a complete line you should have a competent service come work on it.
that would involve empting the whole system pulling a vacuum and recharging the system.

Others have had the same issue;
2565 AC pressure switch
Mahindra 2565
and AP Air parts for 2565,
AP Air Inc - MAHINDRA 2565 TRACTOR
almost to the bottom of the page above, low pressure switch;
Binary Pressure Switch, Drier Mount
it is a common low pressure switch available many places.
I'm curious you put in two cans what was the low pressure side reading while you did so?

There is a 100% reliable $50 parts and labor end around for a failed low pressure switch that any competent service tech can install.
For many years a sign hung in my shop.
Labor $10 per hour
Labor if you watch $15 per hour
Labor if you fixed it first $30 per hour
After a few neighbors missed the point and thought I would work for $10,I recently added a second sign.
Due to present Whitehouse administration fixing what the past administration screwed up,we are forced to quadruple labor rates.
Everyone should have the skill and tools to practice at least one service well. When you find yourself in OP's position, I recommend hiring your skill out in spare time to pay for your ac professionally fixed.

OR learn the skill you do not currently have, buy the tools needed and take care of the problem. Many things I learned cost me more than having it "professionally" fixed but the next failures were covered. I like learning......

That's great if one likes changing sprinkler heads, maintaining aerobic septic,clean coils and change ac filters,change car oil and filter but not repair and servicing tractor ac unless you have 50 tractors with ac. Afterall ,how many times does the average person need to repair their tractor ac?

Big difference between repair and servicing. And a huge cost difference in being able to add a bit of gas and keep an older system going and working good compared to having a service tech come out and do about the same thing. Especially when they get to being 15-20 years old.
Even changing out the low pressure switch, most anyone can do it. Gently bleed down the system pressure when it get quite low, unscrew the switch, screw in the new switch and recharge with a few cans that have oil in them. The system will not even need to be vacuumed as long as it never goes to zero psi it will not have any air or moisture in it.
Is it the "environmental sensitive way" nope.
I'm also a fan of doing all you can before calling a "professional" to many of them are simply parts changers. How many of them will find a leak and solder or braze a joint that has vibrated or pulled loose after many thousands of hours.
Then on top of that I'm a fan of R-290 or dry propane works good.

Not just tractors replaced compressors on 2 trucks, rebuild a few insurance totaled cars requiring ac components to replaced along the way, etc. My $200-400 investment has saved me thousands. I also have high end scan tools for my vehicles and learned to repair them. I've been working on everything you can think off since I was a teen. Lawn mowers to Jet Aircraft, PCs to Mainframes, hardware to software. I do not know everything by far but I CAN learn. I hate throwing parts at a problem that is the way of the professionals these days. I been in the business many "techs" don't have a clue and their bosses none at all. I'd rather pay a good pro to come teach me how - rather than fix it for me.

Clearly I should be content wearing the dunce hat and deferring to Lou and you instead of offering advice on these things. To show what a push over I am,they charged me over $200 for a multimeter and after hearing what you spent to outfit your garage for all those trades I'm embarrassed to say what I spent on ac specialty tools alone.
I'll get out of the way while you and Lou walk mookey through the process of getting his ac up and cooling.

It's a life time of tools, a little at time. Reality is when I needed an AC compressor replaced the local shop was wanted $800-1200 for a 15 year old truck. I bought gauges, a vacuum pump, a used compressor, some AC Oil and some 134a under $400 all shipped to door. Crash course on line, never trust on source for anything in life. Swapped the compressor, pulled vacuum made sure there were no leaks. Added some oil and charged the system to factory spec per the official oem service manual. Been working for 5 years no recharge needed. My son't truck went out the next summer same deal, same type of truck. Only had to buy parts less than 100 and spend a couple of hours. Had to repair a few front end collisions from my wife and daughter, bought the wrecks and rebuilt.
I had multiple vehicles the pros had for months with out fixing, had them towed to my house and fixed them using the same manual they have.
Now I have been a techie on the clock working all over the county for most of my life. I walked away from a high end gig ( 1 of 5 in the USA) because I had enough. I've taken more training courses for different things than I care to remember. A lot of them in my "spare" time because I want to know. I stayed in "school" while working 60-80 weeks for 20+ years because tech moves fast and you have to keep up or become outdated. I started as Motorcycle mechanic, enlisted and became Aircraft electrician and the moved into the industrial world. Along the way I picked up a working knowledge of all kind stuff. I can write code, debug code (much harder) and fix most anything worth repairing. These days my time is mine and free for me to use but not collecting $300+ per hour from some big corp.
I'm not your average tractor jockey but way more redneck than most farmers and not afraid to work hard and get dirty. I've get a lot more done now that don't work on other peoples stuff, and learn new skills like welding, butchering , hunting and raising livestock.
I still have my Fluke multimeter from 30+ years ago and it works just fine, pretty sure it was well over $200 in today's dollars back in the 80's
Now to AC here not much you can do with out a set of AC gauges.
