fittings?

[tempforce]

the hydraulic fittings on our tractors. are they a standard size or something else…
also need a good source for a control valve to operate a hydraulic motor. it needs to direct flow to the return hose when the hyd motor is idle and when running. the valve will need a detent in open and closed positions…

please direct me to a source for what i need or to someone who is able…

thanks a whole bunch..

my first major project is to convert a brush chipper to hydraulic power and mount it on the 3 point.
the next project will be using the same method.. is to mount and power off the hydraulics a cement mixer on the three point.

Wouldn't it be easier to buy a cement mixer thats already built for the 3pth and runs off the pto?

Depends... Farm tractor& mid size Kubotas use fittings compatible with 8010 series ISO Poineer tips. O-ring or not on the back/threaded side probably depends on the year of the tractor. Don't know about the little tractors.

BTW, how big is your hydraulic pump on the tractor??? You may be dissapointed trying to run a chipper off of the hydraulics. Most high load/high RPM applications like that require an auxillary pump on the front of the tractor or on the PTO. You will need to match flow rates of tractor and the hydraulic motor you want to use. Likely that you do not have enough flow for a chipper type application, about anything should run a cement mixer though.

My M4500 (50 HP) only has a 7.3 gpm pump. Small hydraulic flail mowers (I'd think a similar hydraulic power demand) will "work" with 10 gpm, but 20 gpm would be more commonly recommended.

running the chipper off the pto is an option. also a pto driven hyd pump wouldn't be that bad, just a bit more $$$ to build…
the tractor does have a low gpm output. so a speed increase would have to be factored i.e., two pulleys of different sizes, instead of direct motor to chipper drive shaft.
thanks for the link to the 3 point cement mixer. i book marked the unit for when i get to that part of the project..

There is also various pto chippers you could use.
