Hey guys, I'm working on my Sunflower field
cultivator. It is an older one, has wings
and 4 lift cylinders. The depth stop valve
was not internal to the cylinder, it was an
external device mounted inline before the
first lift cylinder. It had gotten rusty
and ruined it before I got it, and leaked a
lot of oil, so I had just bypassed it for
the time being. Parts for the depth stop
are no longer available, and a newer style
depth stop valve is about $1500 from
Sunflower. So I found this Parker cylinder
stroke control valve for $60. I think it
will work just fine, but I have a question
on my plumbing. All of the cylinders are
plumbed in a loop essentially. The one hyd
line runs into the bottom of the first
cylinder for lift, then comes out the top
of the same cylinder and goes into the
bottom of the next cylinder. And so on,
until it ends with the last hose coming out
of the top of the last cylinder going back
to the tractor. Could I use this valve
inline at the inlet to the first cylinder
of the group like the last one was, or will
I have to split it between the first 2 lift
cylinders as shown? Here's a picture of the
valve I plan to use. Thanks guys
