 PTO Upper Control Arms Stuck in Upward Position

Hopefully someone has experienced this before: My tractor is a SD2843T. Last week I hitched up my brush hog with plans to cut the field for the first time. I got the mower hooked up and activated the lever to lower the mower deck, but instead of going down, the deck shot straight up. It won't lower. Or should I say the rear PTO control arms won’t lower. The pressure gauge needle spikes when I push the PTO control, so I know I’m pushing fluid. However, the control valve for my loader also leaks fluid from the front caps when I put stress on the PTO lever. The loader’s control valve is a Prince model 5000 Mono block two sleeve, three position that only controls the front loader. The PTO control is electric and sits to right side of my seat mounted on the fender. All fluid for both front and back run through the Prince control valve.
This tractor has two hydraulic pumps mounted back to back on the right side of the engine in front of the starter. The rear pump has a cylinder housing for a screen filter. I emptied out all the hydraulic fluid. I took the filter out and inspected it. It was very clean. I blew air through the line running up to the control valve. I disconnected all the lines running into the control valve and took it apart. I replaced all four O-rings and inspected it. It looked fine, so I put it all back together and remounted it. I took the electric control switch box off the fender and took it apart. I cleaned all the contacts and checked continuity with a multimeter. It works fine. I also took the time to change the engine oil and flush the radiator. After all that, the rear control arms are still stuck in the upward position. I finally got another tractor, lifted the brush hog up and dismounted it. If anyone has ever had a similar experience with a Grey Market tractor, I would appreciate knowing how you fixed it. The Grass keeps growing.

Don't know that brand but since it's controlled electrically, that would seem to be where to look. Also, most have a lock- or stop-valve that you close to keep the hitch up, and maybe this got triggered.

I'm not a Shibauru guy, but Len Sheaffer will hopefully see this topic and lend his expertise. Best guess is that a dirty loader controller is stopping the flow to the TPH hydraulics. The controller probably needs a good cleaning.

What I can do for you however, is assist with your terminology. PTO and lift arms are apples and oranges. The PTO stands for Power Take-Off, and is the stub behind the tractor that turns the driveshaft that powers your mower. Upper and lower lift arms are components of the TPH (Three Point Hitch). Their respective operations are completely unrelated to each other.

The electric over hydraulic are really hard to diagnose. If the switch & wiring are good, the end of the solenoid should be magnetic. Many of the solenoids have a hole in the end through which a nail can be pushed to activate the valve.

Japanese terminology can be tricky. Fuji Heavy Industries (named after Mount Fuji) has seven components (such as shipyards), and named its car division Subaru, the Japanese name for a 7-star constellation. Shibaura is a once-industrial suburb of Tokyo where Shibaura tractors started. ("Toshiba" is a contraction of Tokyo Shibaura.)
