Well, my new 318 is now fitted w/ a Johnny Bucket and I'm having a great time moving dirt from here to there.

However, I'd love to reproduce the lockout valve so that I'm not spending time and energy moving the rocker cylinder when I'm manipulating the bucket. I get a 2-3 second delay on dump/scoop as the rocker moves first, then the bucket gets powered.

I've found some inexpensive, hydraulic ball valves that should fit, but they're only rated from 3000 psi. Is that high enough, or do I need to step up to the 7K edition?

Thanks all!

Allen, 3k is plenty. I think the external hydraulics pressure is limited to 600lbs on the 318 if my memory serves me. I had a diverter valve on my x475 but it was installed at the dealer when the tractor was new, so I don't know exactly how it was done. Looking at the 318 hydraulic diagrams it looks like you would just put the valve between the rockshaft cylinder high pressure line and the T that feeds both the cylinder and the left remote outlets. I have never seen a 318 up close so I don't know what that would involve.

I put a ball valve on the rearmost hose on the rockshaft cylinder. Works great.

3000 psi is much more than the 318 is capable of. Put the valve on the line going to the blind end of the left cylinder ( the side without the piston rod).

Excellent, thank you guys for the insight...I'll try and get it installed soon and see how much time I can save between bucket loads.
