Mahindra 2545 on sand

number scales are different for different types of oil. Heres a chart. Read Horizontally to see how viscosities relate.

OK so I learned some things today..

The 2545 hydraulics use the transmission oil. Operators manual calls for 80W gear oil for the transmission which is similar in viscoscity to hydraulic fluid.

Im going to call the hub dealership tomorrow and ask if I should use 80W gear oil as the manual states or UTF.

[edit] Here is the bucket after I had been using the tractor for a while and had cycled the curl. I don't think I had cycled it enough in that video, I noticed that it was really bad yesterday when I first started the tractor. Just with my hand there was over an inch of seemingly free cylinder movement. I cycled the curl a couple times and it got slightly better. Cycled it more times and it got slightly better. There was still play in the bucket, from the cylinder moving, after having been cycled 8 or 10 times. I'm pretty sure I could hear air in the system at the very end of the curl motion. I'm beginning to wonder if it needs to be properly bled.

OK, just talked to the hub dealership where they do all the service work on the tractors. He said that they use Service Pro Universal Transmission and Hydraulic Fluid. Service Pro has two products, "premium universal hydraulic tractor fluid" and "Premium Low Temp Tractor Hydraulic Fluid". I'm assuming they are using the former. I would consider neither of these to be 80W gear oil as the manual states should be used in the transmission.

Anyway, I guess I'll be looking for a high quality UTF as SPYDERLK said. Thanks for the input, it is greatly appreciated. I am glad I finally get some closure on this topic.

The KEY thing about the universal tractor fluids is that they have Extreme Pressure additives like gear oils do, and therefore hold up fine in a transmission while ideally suiting hydraulic and wet brake applications.

GL4 80W-90 would work, correct?

Universal tractor fluid. Period.

Spent a bunch of time on BobIsTheOilGuy. Apparently Schaeffer makes some of the best lubricants you can buy, as good or better than Amsoil or Chevron. I'm assuming this would fit all the minimum requirements for the transmission -

I know I can buy oil for less. Can someone confirm that this is as good or equivalent to UTF that you would get from TSC?

The copy paste is rather disappointing but the #s are there.
. . . I have hilited the cool and hot viscosities. These numbers demonstrate the high Viscosity Index. Essentially they show that the oil is as thin as the thinnest 85W wnen both are cool - and as thick as the thickest 85W when both are hot.

IOW, it is your friend; flowing nicely when cold/cool and staying thick enuf when hot to lubricate and seal well.

Ill wager this is way better than any generic UTF youll find. It would be nice to compare it to Kubot SUDT and other touted high performers.

What does it cost? --- SUDT is probably near $20/gal. Generic UTF is around 9 or $10.

It is $27/gal with 2 day shipping. The pennzoil I was looking at was similar at over $100 for a 5 gallon bucket. There are some people on the oil forum that seemed to know their stuff (send off their oil for analysis) that only use schaeffer products so I'm thinking this product should do well. By the description it seems to be intended for this exact use (shared sump trans/hyd).

Why does curl on my tractor get air in it as im working? I cycled it, worked for about three hours. I could tell it was getting bad towards the end. I checked it and I could move the cylinder in/out well over an inch by hand. I cycled it to its extremes three times and it stiffened right up. This cant be normal..

Thats extremely expensive. Might be worth it.

Your "air" has to do with the dumping action of the bucket. There is pressure on the rod side of your curl cylinders just to hold the bucket lip up - extreme if holding a load. To dump, this fluid must be bled off while hopefully routing enuf pump flow to the base end to keep it full as the cylinder extends. If the base end is not kept full the bucket will get floppy. This is probably what is happening. However many loader valves have regen on the dump circuit to deal with this. In the hard rightward position it applies pressure to both ends of the curl cyls. Since there is more working area on the base ends there is a net extension force on the cyls causing dump. But since equal fluid pressure is on both sides no fluid void is allowed. Indeed fluid escaping from the rod end is used to supplement pump flow into the base end.

So try dumping fully with hard right joystick and then curl to the position you want. ... It should be firm.

Heres a video about regenerative flow:
