BX25 Hyd. service questions

[Orange2009]

So when I first bought my Kadota the x25 I was leery about the performance of the background and weather that little tractor would really be able to power it. Much to my surprise it handled the bucket extremely well actually better than the front end loader. nowadays it seems that it doesn't take too much work for the Backhoe to cause the hydraulics to get really hot and start to whine badly, Of course this also means an extreme lack in performance and power as well as speed, Fluids have properly been changed as well as filters, now I do change implements quite often so there are chances that dirt and grime could get in some connections. I have read on here that the older tractors have a plug you can take out of the hydraulic pump and there is a screen that needs to be periodically clean is this the case with my BX 25? I'm just trying to figure out why my little tractor has lost so much power when is hydraulics get warm it even affects driving and high range it won't climb a hill and just screams really bad.

info that may help:
2009 BX25
Mostly effected when using BH/FEL
36x hrs
use kubota fluid and filters
fluids are at proper levels.

I would suggest that you check the HST cooling fan first.

I see on another post that you have some engine overheating issues as well due to a cracked radiator / shroud / fan. If the tractor has had that rough of service to have those parts break at only 36X hours, then most likely you will find that the HST cooling fan is broken as well as it even less protected it seems.

At least that is my first thought.

Please post what you find.

Does it have 36 hrs total or 36 hrs since the fluid was changed?

What type fluid did you use when it was changed?

No there is 360 hours, and the shroud has cracked at some point int time, unknown why but I hear that it has happened to others from the movement of the motor allowing the fan to move enough to just tap the shroud. There isn't much of it broken but enough to cause some air to pass in front of the radiator instead of through it. As far as hydro fan yes I have broke that. Actually driving across my lawn after spreading mulch, a twig about the diameter of my peenkie popped up and shaved the blades off. Fortunately I heard it and saw the parts right away so the pump never ran without cooling. The fan is good as we speak.

I went ahead and bought all new fluid, filters and will be servicing and cleaning the oil screen as well this weekend. Hopefully that is the issue.

Additionally my dealer said there was an update to the engine mounts that made the engine sit a bit more solid.

I hope you went with SUDT2 fluid and not just UDT.

This I did. BUT gonna wait to change it until the shroud comes in, that way I can kill all birds at once. What's the difference though?

SUDT2 is semi-synthetic and UDT is dino

I'm not trying to sell you this, only offering a different product.
If you want the highest level of protection available for you tractor including: coolest operating temps, smoother hyd function winter or summer, best fuel economy, up to 3x oil service life might want to look into Amsoil. JMHO
