our 4430 was pulling a sprayer when hyd functions became slow steering slowed and tractor acted like clutch was slipping we changed filters tryd the destroke valve and made sure screen was clean none of that has done anything it had a power beyound on it but we took it off cause it was suggested that could have contributed to the problem now dont know witch direction to go any suggestions:banghead:

Since the problem includes clutch slippage, I suspect no problem with main hydraulic pump or high pressure circuit problems. Problem more likely in a worn transmission pump, leak in a transmission clutch or circuit, stuck filter relief valve, etc. type of transmission depends on where these components are and how to test for the problem.
