4x4forks 258 #1 Posted October 10, 2019 Latest improvement to the Orange beast. Auxiliary Hydraulics. I wanted to make a hydraulic top link and a snow plough so I have made a tapping for the hydraulic line ,Made and mounted a bracket to mount the twin spool valves up out of the way . I am going to improve the pluming to keep it nearer the spool. Currently all fitted and not leaking. 3 Stormin, Cub Cadet and expeatfarmer reacted to this Share this post Link to post Share on other sites
hortimech 0 #2 Posted October 10, 2019 It looks like your spool valve only has two hydraulic pipes going to it, if so, then it is the wrong spool. you need a spool valve with 3 ports, in, out and power beyond. the in comes from the take off block you have fitted at the front, out dumps back to the axle and power beyond is the return to the take off block. If you don't use the correct spool, you get back flows etc and strange things start happening. You should also check that the PRV in the spool is set lower than the main tractor PRV.

4x4forks 258 #3 Posted October 11, 2019 Sorry but you are incorrect. Everything works as it should. rear lnks and both spools work find full control no problems. Share this post Link to post Share on other sites
hortimech 0 #4 Posted October 11, 2019 You might think everything is working correctly, but let me assure you that isn't. I didn't spend 25 years of my working life, building, servicing and repairing Kubota tractors without learning something, you really need a 3 port spool valve. I have seen split top cases caused by using the wrong spool. Share this post Link to post Share on other sites
4x4forks 258 #5 Posted October 29, 2019 Well the hydraulics are working fine and i have made the snow plough attachment fit the front. It needs finishing as lots of metal cut with plasma needs grinding and then painting but the geometry works 2 nigel and Stormin reacted to this Share this post Link to post Share on other sites
