I've read several threads about how Kubota routinely sets hydraulic pressure lower than what's claimed in the literature. I've always felt that my loader wasn't lifting what it was really capable of. Last fall I loaded my 5' brushhog onto a flatbed trailer. The cutter weighs about 500lbs. I couldn't lift it any more than about 30" from the ground so it was a struggle to get it over the sides of my landscape trailer. I've got a B3200 with a LA504 loader. From what I've read I need a pressure gauge which can be inserted in one of the front loader hose ports to check the pressure on the system. Once the pressure is determined there are shims or washers that can be inserted to raise the pressure on the system.
My questions are these -
When installing the pressure gauge (with the hydraulic system quick connect) I'm assuming the tractor must be shut down and all the pressure relieved on the system - correct?
Once the gauge is in the loader hydraulic block, I fire up the tractor to operating RPMs and read the gauge as I cycle the loader control handle. If the pressure is lower than what the literature claims it is how do I determine which shim/washer is needed to raise the pressure? Are multiple shims/washers added or are there different size shims/washers?
The shop manual doesn't have a really clear photo of where the shims/washers are added so any info on that would be helpful.
Thanks
