Puma, pto hydraulic pump question.

If you are somewhere near right on pump size with a Landy PTO you have the choice of gear selection to increase/decrease pump speed without having to rev the engine too high. On the cherry picker some of the lads use it in third gear at idle and others choose 2nd gear with a bit of a rev. There is a window of adjustment there as long as pump max rpm are not exceeded.

Kinell I am having another senior moment. What I meant to add in the above post was the cherry picker has two circuits with different flow requirements, the winch and the hoist. The flow requirements for the winch are a lot higher than the needs for the hoist. For the winch it needs to be in 4th gear and on a rev, if you tried to use the hoist with that flow it would flick you out of the basket. Hence using the gears to reduce oil flow.
