Lift of belly pump redux...

So... I think I hear from previous post that putting 2 cylinders rather than only one on 3 point powered by stock "lift all" gives no mechanical advantage???

Two cylinders will double your lifting power, but cut your lifting speed in half.

all depends on what size cylinders your talking about. its all about displacment of the bore.

Just ONE cylinder is powerful enough to lift anything that SHOULD be on a 3 point behind an H or M. If you need two cylinders to lift the load, then you are going to need a stack of front weights also.

If you look back, the two cylinder version of the Saginaw hitch is widely preferred over the single cylinder. Not only do you get more lifting power (which you probably don't need), but you get more "even" lifting (which is probably not necessary either for typical use).

With a single cylinder, there is some twist imparted in the rockshaft that connects the two sides, during heavy lifting, plowing, etc..

Zactly. They do want to twist the rock shaft with just one. And can if worked hard enough. A pair of 3" (I think) creates enough force to break some lighter implements, like boom poles, and will easily lift loaded rear tires off the ground.
