hey all,
I have a ford 1210 tractor. It is 16 hp, 15 hp at the pto.
when i bought the tractor at auction, it came with a Ford 916A belly mower, however, none of the stuff to actually mount the mower deck to the tractor.
A little background:
over the years, i have welded up some things to mount stuff to the front of the tractor. Ive made a plow, an upside down wood splitter (kinda like you see on skid loaders), and some other things. so i decided to mount this mower deck to the front of the tractor and power it via my pto hydraulic pump and a hydraulic motor mounted to the gear box of the mower.
I originally bought a 16 gpm pto pump for running the log splitter. I am able to get pretty good gpm flow without having to run the tractor wide open. I get about 11 to 12 gpm at 2000 rpms. I had to set the pressure relief to approximately 1400 psi because the tractor just isnt powerful enough to maintain 12 gpm at higher pressures, but it works fine with the log splitter. Honestly havent run into much that i couldnt split with the 4" cycliner...
i will try and paint a picture to best describe my setup for how i run the different implements on the front of the tractor:
starting from the rear moving forward i have the following setup:
so as long as the implement has the correct male pioneer couples i can easily attach and disconnect from the front of the tractor.
For the mower:
NOW, FOR THE ISSUE I AM HAVING:
When i put the hydraulic motor in gear (aka move the lever on the control valve one way or the other cuz i have a reversible motor), the motor spins perfect... however, the pressure reading in the pressure gauge i have installed at the inlet of the control valve reads 1000 to 1100 psi.
Remember, i can only have about a max pressure of 1400 psi with my setup (which is what i have set the relief valve to), so 1000 psi is really working the engine. its too much to the point where you can barely mow with it because if the pressure builds much more it wants to stall the tractor completely.
i tried disconnecting the lines from the cross over relief valve and connecting them directly to the hydraulic motor, the same thing happened with 1000 psi. i thought maybe there was some kind of restriction with that valve.
I tried disconnecting the hydraulic motor from the gear box of the mower and i still get about 800 psi just turning the motor alone... i feel this is still too much. how can it take 800 psi to just turn the shaft of the hydraulic motor when its not connected to anything? literally just the shaft of the motor spinning, disconnected from the mower completely.
Everything i have is plumbed correctly or else the system wouldnt work at all, everything is rated for the gpm i am using (i am putting out about 11-12 gpm). I cant imagine it takes that much pressure to turn the motor, i was thinking it would be more like 200 psi... not 800 (and definitely not 1000 psi when its connected to the gear box). i figured the pressure would spike when you first put motor in gear, but once the blades get up to speed i thought it would go down to a reasonable reading (like 500 psi). the way it currently operates at 1000 psi makes it unable to actually cut grass... too much load on the tractor.
what do you all think the issue could be and what i could do to lessen the pressure? I was told by two differnt people that i should swap out the 1/2" hoses for 3/8" hoses... they say the pto pump wouldnt have to pump as hard for the pressure to build to turn the motor but to me the pressure would go even higher if i got smaller hoses. pressure is only made from resistance and the only resistance i can think of is the fluid flowing through the hoses and turning the motor (because i get 1000 psi not even cutting grass, just the blades spinning above the ground). i was thinking i should go to larger hoses like 5/8", thinking the larger hoses would make less resistance for the fluid flowing through them, but i am lost, there has to be a way to get the pressure down... or maybe i am just completely wrong and it really does take that much pressure to turn the motor and my tractor is just not able to do it... i know that pto pump is a lot of flow, but it always worked perfect on the log splitter, i definitely didnt think there would be any issues with turning the little gear box on the mower.
i apologize for the long post, just trying to do my best to describe my setup and the issue

i will try and paint a picture to best describe my setup for how i run the different implements on the front of the tractor:
starting from the rear moving forward i have the following setup:
- 25 gallon hydraulic reservoir with return line filter rated for 15 gpm, return line is connected to control valve with flat face coupler so i can easily disconnect it any time if i want to take the reservoir off the 3 pt arms.
- 16.6 gpm pto hydraulic pump with 1" suction line from tank and 1/2" hydraulic feed line to control valve
- 21 gpm single spool control valve with pressure relief set to approx 1400 psi. i have the feed line on a flat face coupler (rated 20 gpm) so i can easily disconnect the feed line from the control valve if i ever wanted to hook the pto pump up to something else (like if i got a back hoe attachment or something)
- from the control valve going forward, i am running 1/2" ID hydraulic lines along the frame to a bulkhead mounting area at the front of the tractor, there i have pioneer couplers rated for max 24 gpm of flow.
so as long as the implement has the correct male pioneer couples i can easily attach and disconnect from the front of the tractor.
For the mower:
- i connect 1/2" hydraulic lines to the pioneer couplers mounted to the front of the tractor, these lines run 3 feet to a cross over relief valve that is rated for 19 gpm.
- from the cross over relief valve, i run 1/2" hydraulic lines 2 feet to the hydraulic motor.
- the motor i picked is 3.05 cubic inch rated for 15 gpm at 1100 rpms
