What J Schwiebert stated is right-on. It depends on the loader and what size cylinders it has. The bigger the cylinder, the more longer they take the fill and the bigger pump needed for speed. Generally, the bigger the pump the better - since it will work a lot nicer when the engine is running slow. As long as you have an open-center system, and the valve is big enough not to obstruct full-time oil flow, a big size hurts nothing. Also keep in mind that when you cite GPM figures - they mean nothing without RPM. One pump will be rated at various GPMs at different RPMs. Cubic inch displacement is a more reiliable figure. Generally speaking most good loaders use with engines that run a max of 2400 RPMs use 23 GPM pumps. Some light duty loaders with small cylinders use 9-13 GPM pumps and work kind of slow.
My IH 3414 backhoe loader uses a 9 GPM pump and is just barely adequate.
My IH B-275 with a farm loader has a 7 GPM pump and is very slow.
My Ford 4000 loader uses a 23 GPM Cessna pump and it works great.
My Ford 641 with a farm loader has a 23 GPM Cessna and works very well.
My Deere 420 crawler-loader has a 13 GPM Cessna pump and is slow.
My Deere 1010 crawler-loader has a Webster 23 GPM pump and works great.
My Case 580 CK loader has a Cessna 23 GPM pump and works great.
My Oliver OC4 loader has a 23 GPM pump and works great.

Today's Featured Article - Listening to Your Tractor - by Curtis Von Fange. Years ago there was a TV show about a talking car. Unless you are from another planet, physically or otherwise, I don�t think our internal combustion buddies will talk and tell us their problems. But, on the other hand, there is a secret language that our mechanical companions readily do speak. It is an interesting form of communication that involves all the senses of the listener. In this series we are going to investigate and learn the basic rudimentary skills of understanding this lingo.
