I have a 90 something Honda H5013 4wd tractor. It's a small tractor
as tractors go but it is a real workhorse. Anyway, it has a 4 foot
dozer blade that has 3 positions, left, right, and center. I would
love to be able to swivel the blade using hydraulics, because then the
angle would then be whatever I want and I wouldn't need to get off the
tractor to adjust the thing.
So I started thinking about getting power from the tractor
hydraulics and it would just plain be better and easier to have a
separate hydraulic system for the front blade.
I think a power steering pump with built in reservoir would be
perfect. If it will work.
The rotation of the pump and the front PTO shaft would need to be
the same as would the RPM, which is 2650 tops on the Honda.
I want to use a double acting cylinder. And I think an open center
valve the type of valve that should be used but I don't know. The
valve must allow the hydraulic fluid to flow back to the pump when the
spool is centered while at the same time holding the cylinder in
One advantage of using the front PTO is that it is easily engaged
and disengaged so that the pump won't need to run all the time. The
PTO can be engaged or disengaged at any time just by moving a lever.
Has anyone here done this? Do power steering pumps spin as fast as
2600 RPM? I think the one in my Toyota truck does. Is an open center
valve the right one?
