Yanmar SA324
Before I installed the post driver, I had a dual rear remote valve installed by the Yanmar dealer. The mechanic and I discussed that a power beyond was really the ideal way to power a post driver, but I decided to get the dual remote valve instead, in case I want it for other stuff in the future. The downside is, I have to rig the lever up or down while operating the post driver, and accept a slightly lower flow rate. But it worked fine during my trial run, so I think I'm happy with the decision.

Shaver provided all three hoses needed for the HD-8, and the fittings to connect them to the control valve on the driver. I had to purchase a quick disconnect fitting to connect the supply hose to the remote valve, and also an adapter to connect the discharge hose to the hydraulic tank (in place of the cap).

Shaver offers adapters for various tractor models, but when I talked to them their list only had the old Yanmar model numbers, so I didn't buy one. The Yanmar mechanic knew exactly what I needed and called around locally to find an adapter. One end has male threads which match the hydraulic reservoir fill port, and the other end has female threads for a 3/4" hydraulic fitting. I also used a 3/4" 90 deg bend with swivel to attach to the discharge hose.

There wasn't quite enough clearance above the fill port to install these, so I trimmed a little metal to make them fit. See the pictures below. In the next post, I'll cover operating it.

You could get a "detent" put in one of the remotes. That way it 'locks' in place, holding the valve open.

Looking to purchase a Compact Tractor in 30-50 HP range.
I'm curious if this is specifically a Yanmar problem or just the same problem with any SCUT or small CUT? Does Yanmar have some unique 3pt hitch feature?
