I 504 gas hydraulic issues

darrell vanderwaal When I put my finish mower on the tractor the tractor won't move immediately. On small inclines it takes a minute r two to build enough pressure to move. Larger inclines take longer to move. I've been told it could be a filter problem, a hydraulic pump going out. The filter is inside the pump and like most things on this tractor not easy to access. I've heard you can mix some kerosene in with the hydraulic fluid for the hydraulic pump to help clean the pump n restore the pressure in place of taking everything apart to simply change the filter n or the pump. Does anyone know if kerosene would do the job? If so, how much kerosene gets mixed in with the fluid? Then does it need to be drained after a certain amount of time and new fluid put in? Or is it better to bite the bullet n tear it down and replace the pump? What about any damage to the parts mixing kerosene in with the hydraulic fluid?

Thanks for your time.

IHTimmy Darrell. I would recommend adding 4 to 5 gallons of diesel fuel into the rear end Run it drive it then drain it get a new filter and hydraulic oil The hydraulic filter is not in the hydraulic pump
