I have not found the problem yet, bought a gauge and fitting to check the pressure but haven't gotten to that yet. Was thinking about extending the hose with a metal section for cooling. My fluid is the UDT2 that Kubota calls to be used in that particular model and the fan appears to be working...

Yes, fan has all the blades and looks like it is working correctly.

I am told that my bx1800 hydraulic fluid is heating up and allowing the bypass to activate and stopping the PTO. I have changed the fluid, am using the right fluid, have rebuilt the PTO clutches and replaced the bypass spring to still have the problem. Operation in 70-80 degree temps don’t cause...

I am having a problem with my bx1800 mower stopping mowing (mid pto shaft stops turning) after about 30 minutes of mowing. I have rebuilt PTO clutch and replaced fluids and filter. It seems to only do this in temps above about 85 degrees. Was told by a tech this is due to high hydraulic fluid...

I have an 1800D that would mow for a while then the blades would start to slow and finally stop (PTO WOULD QUIT TURNING). After talking to several people who told me it was the PTO clutch I tore into the transmission and replaced the clutch plates and anything else that looked worn. Clutch...

I am in the process of tearing down the transmission on my 1800D to replace the PTO clutch components and while draining my transmission fluid I had a ball bearing fall out of the drain hole. I found that the final gear shaft in the transaxle wobbles when you turn it which leads me to believe...

I had thought that it might be the clutch plates or something related to the PTO that drives the blades but was hoping for something less involved. Even when the blades slow down the lift hydraulics and power steering seem to work fine. Also, the mower forward and reverse still works as usual...

Yes, it was the s-udt2 and i used a oem Kubota filter

the fluid and filter were changed just at the beginning of this mowing season. It shows to be between the marks on the dipstick.

I have been having the blades to stop turning on my BX1800 after mowing for about 30 minutes. It mows fine up until you start approaching that time and start running into heavy grass. You can slow way down and it will still mow some but eventually will stop all together. The drive shaft just...

I changed the filter and fluids and screen. After a while the blades began to slow as they had before. What would you suggest I try next? Thanks, Don

Not sure when it was changed, I bought it from a person who had gotten it from an auction house. I am in the process of getting fluids and filters and will try that first. You mentioned about the relief valve, I know that the mower is about 20 years old, should I go ahead and try to replace the...

I have a BX1800 that works fine on start up but after mowing for about 30 minutes the blades begin to slow down and finally stop turning (drive shaft not turning but rear PTO shaft still turns but not very fast). If you turn it off for a while the blades start working again. I have been told...
