Hydraulic question

   / Hydraulic question #11  
So then you would be using the bucket curl valve to operate the lift and lower function on the loader arms? I'm thinking that won't work as it will cause the loader to not have enough power to lift or, if the hoses are reversed, may cause the loader to free fall when the valve spool is shifted.

Guess I would look at using the rear remote if you can figure out how it operates.

Does the regen spool have just the three positions where non-regen bucket curl is not an option in a fourth position?

Edit: Looks like SPYDERLK and I were posting simultaneously.

That should work fine as long as the regenerative dump is used to raise the loader arms (although with a weaker lift than "normal").
The issue is that regenerative dump ties both sides of the cylinder together and then puts pump pressure to them. The difference in surface area between the rod end and the base end of the cylinder (due to the diameter of the rod) causes the bucket to dump.
This does not work on a snow plow such as what the OP is referencing because the surface area is the same for both directions (as plows generally use to single acting cylinders).

The power to lift will be limited to the effective area of the cylinder rods as aczlan mentions. That will limit the lift power to about 1/3 to 1/2 of normal depending on the ratio of rod diameter to piston diameter. That may be enough depending on the weight of the plow and might be worth a try.

Something to keep in mind is that you won't be able to level the plow once the bucket hoses are disconnected and attached to the angle function. Would need to be sure that the plow is level when angled prior to disconnecting the hoses. Another issue to keep in mind is that you won't have float capability on the lift for plowing after switching hoses. I'm assuming that you have float mode on the lift spool but that may not be the case.

Good luck in which ever way you end up going.

We ended up switching the hoses and ran the curl circuit to lift and lower the plow and the lift and lower circuit to angle the plow
It seems to work ok
He is only doing his own driveway and will have to adapt to the reverse function at the loader control.
Thanks for everyone's input
