hydraulics on a ford 75 with 18 hp briggs twin

im putting a 18hp briggs twin on my ford 75 and am wondering if there is any way to run a hydraulic pump off the pto jackshaft and still keep the ground clearence i have. i want to use it to power a pistion for a snow blade or run a small log splitter and have a ddriveable log splitter that i could hook up on the back of the tractor using a homeade 3 point hitch and minute mount style quick release line fittings, or maybe a small loader. anyone have any ideas on what kind of pump to use and where a good place for it would be?

the gas tank platform has been removed for carb clearence and the gas tank is going ot be put under the seat. the battery is going underneath the intake if it wont fit in the stock location behind the motor

Your 2 hydraulic tasks are not mutually compatible. Either the plow lift will be fast in the extreme, or the log splitter will be slow in the extreme. Unfortunately, there is no middle ground for a compromise that will in any way be acceptable. The plow lift with a 2" cylinder requires no more than 3 gpm flow and even a small 3" cylinder for a splitter will be not fast with twice that flow, and it won't be very strong. A FEL is barely compatible with a splitter, but again, the splitter will be slow. I run a 3.5" cylinder with my loader's 6 gpm hydraulics system and know that it works, as long as you're not in a hurry or run into hard to split blocks.

A loader is not a good plan for a lawn tractor. It can be made to work, but the rear end and the front axle are at severe risk. Breakage is a given. For the loader on my GT, I have half again as much in counterweight as what your tractor weighs.

As to where to add a pump, most engines have a provision on the flywheel to add a stub shaft and pulley for driving attachments. My GT drives the transmission and the rear PTO from such a shaft. I'm not sure how easy it will be to fab one up for your B&S.

For an implement lift hydraulic system, a GM power steering pump with a remote reservoir works well and doesn't use a lot of space.

i hvae all the pums and cylinders off an old spltter that was retired due to a blown motor and bent frame i figured if i coulld run a pulley that was the same size as the pto pully i would have a 1:1 ratio and it would be just as afst and powerfull as the old splitter
Splitter pumps are usually directly driven off the engine crank. They aren't designed for the side loads of belt drives.

Just as fast and powerful, yes, for a splitter, but definitely not good for the small cylinder used for lifting a plow, unless you want to put the plow into orbit and clean up the oil spill from a blown cylinder.

ok thanks. im going to talk to my uncle he minored in hydraulic engineering so we may be able to figure something out
Good plan! :fing32:
With vertical shaft motor like yours it is really hard to get the belts to stay tight and get the rpms you need to maintain pressure. Not alot of room on those machines to make it into a splitter. Much better option would be old jacobsen cheifs or similar tractor with horizontal shafts. Much easier to fab a tenser to keep the belts tight. IT could be done with that one of yours but alot alot of fab work would be needed though. I have thought of it on similar machines and decided not worth the hassle.

well after talking to my uncle ive decided that this tractor isnt going to get hydraulics after all. it would take a little too much time and money to get it to work properly
