Amazone Hydraulic drive fert spreader

[iaincr]

Looking at possibly buying an amazone za ts hyrdo fertiliser spreader. The tractor I'd be running it on has 100 l/min open centre hydraulics. According to spec sheet it can be ran using open centre hydraulics with a constant pressure and free return but dealer reckons that oil would over heat if not on load sensing hydraulics. Anyone any experience or thoughts? Tractor is mf 5470 with twin flow hydraulics

I have the older ZAM hydro which I run on between 2 John Deere R series with closed centre hydraulics. The oil is circulating constantly through a free flow return into the backend so I can’t see why it would cause problems with your open centre MF?

Turn down the flow?

Only reason the oil will overheat is if you're trying to shove too much through the motors, and creating back pressure

Doesn't matter if it's closed or open centre. For a wee hydraulic motor, both need the flow rate reduced to something approaching sanity

I think his argument is the oil flow will be restricted by the machine depending on spread width/disc speed, so tractor will be trying to pump 100l but only able to pump 50l for example

That was my thinking aswell, but dealer thought otherwise hence the post on here to see other opinions

I'm on john deere with mine so will be closed centre but they run my za ts either on power beyond or a constant supply through a spool with no bother
