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 temp causing PTO pressure valve to allow bypass. I have replaced the PTO bypass spring and ball at the fluid filter. Was thinking about extending and looping a hydraulic hose to hopefully allow more cooling of the transmission fluid? Could this help and if so which hose would be best to extend?
