You say it's the Hyd. filter, which there are two, is this correct ? Is only one leaking or both?

Should have two....One is the HST filter and the other one is the Hyd filter and this is not a common problem with Kiot's....I am on my second Kioti and I have never had this problem or heard of anyone else having this problem.....I am going to suspect that the issue is the filter.....Where ever you got the filter, take it back and make them give you a replacement filter and that should solve your problem.....

A friend who raced Moto Guzzi motorcycles (back in the 80's) showed me one of the race mechanics' tricks. He put a hose clamp around the filter positioned so that the screw/worm tighening mechanism was up against the engine's casting. This prevents the filter from unscrewing and dumping the oil. Might that work for you?

I ride Moto Guzzi’s.. the tractor of the motorcycle world🙂

VINDICATED!!!!! My Kioti Dealer just told me that Kioti determined the filter was engineered with a defect that results in the filter unscrewing with heat/cool cycles. The dealer had 4 other people within 24 hours complain about the same issue and they reproduced it in their shop. They contacted Kioti who investigated the issue and determined it was a defect in the design of the filter. New filters have been issued (Part # T5855-46531) that are I believe the same filter used in their full size tractor. So I was not going crazy! Don't buy the old filter off Amazon or other locations that may have a stock of the old.

That's great, problem solved.

Thanks for sharing the information!

So, it was grimlins after all. They work in the oil filter factory!!
Glad you got it solved.

It is strange that a simple thing like a spin-on oil filter can give a problem, look at this:

No matter how tight I put on the new filter, it becomes lose. It seems temperature dependent when it gets cold outside (32F) it happens faster. Can I do anything to stop this? When I install a new filter, I can not tighten the filter anymore without fear of damage to the filter but it still works lose. Any suggestions?

I had the exact same problem on a 2022 CX1025hst cab model. When cold it would dump out LOTS of hydraulic fluid after the 50 hr service. I whent to my dealer thinking it was a defective filter. The service manager told me it is a known problem with the HST itself causing over 200 PSI and actually pushing the hydraulic fluid past the seal or blowing the seal out! I took it in and they did a hydraulic pressure test and it is 3 times higher than it should be. It is apparently a defective seal in the transmission itself and the only way to fix it is to replace the whole HST.
They have already replaced 3 HSTs on CX1025 CAB tractors all under 100 hr after the first filter change. The filter from the factory was a different filter than the new replacement filter with a different seal and it was VERY tight and painted on. You should get a hydraulic pressure test done you probably need new a new HST. My dealer has ordered a new transmission for my tractor that is on back order.

Please see below... My dealer is now saying Kioti will only replace the filter not the HST but the filter is NOT the problem. The problem is the HST itself sending high pressure fluid to the filter.
My tractor had a problem with lots of foam in the hydraulic fluid from day one that the dealership could not find the cause of. They even replaced the loader controller but it didn't help. They now think it is most likely the internal HST issue causing the air in the fluid🤔
Do you have lots of foam?
