Great thanks Bud. Passenger side? lol, not sure what I was typing there.
Not yet. Without a gauge I only turned it one time cw. Didn't seem to make any difference. I need to take it to cabelas to have the display replaced at some point. Mechanic said he would test pressure and adj if needed. I may turn the screw one more time if I get time before I take it to cabelas. I have a kubota L35 that has a lot more bucket lift so it has to be set on the low side.

I always make my passengers ride on the box blade or bush hog.
Lol.
Well I took a look at the valve with all lines going in to it and cant seem to locate adjuster. Would it make a difference that mine is not a hydro but a shuttle shift? I plan on buying a gauge but would agree that unit seems to be set on the low side as I've driven quite a few comparable tractor loaders in my day and for its size, the tractor seems a little weak at the moment.
Additional question, on your dash panel, does your parking brake light come on when you set the brakes?
I don't know about the parking brake light. Mine has all the computer stuff and there is a display on the right side. I have not used this tractor much at all. 6 hours is all I have on it. I haven't even seen it in over a month. I may go to the farm Friday, if so I will look for a parking brake light. Mine is a 45H Hydro but I would thing the loader made by woods is the same.

Yes, my dash is all computerized too, I can see the parking brake light symbol in it with sunlight shining on it plus the manual shows it too, doesnt light when I place my parking brake on, asked Cabellas service and they said that of course TYM makes the tractors and not all options are installed on all tractors....really, skip the brake light? lol, seemed fishy.
Any chance you can take a picture of your valve as well would be appreciated. I only have 17 hours on mine.
Thanks

On a side note, my display is going bad. They are going to install a new one when I have time to take it in. Comes on fine but after a while it fades out.

Good to know. Hopefully yours was just a bad one and its not an wide spread issue.
Got down to the farm today. NO brake light when the brake is set. Didn't see one lit when I switched the key on either. Turned the allen screw on the prv 2 more times around clockwise. Had no effect. Maybe I have a weak pump. Will let the dealer check it.
