Kubota 3430

I believe kubotas 3430 puts out 8.3 gpm. Is there a way to get more gpm's out of this tractor other than pto pump? I need to get about 12 gpm's

The PTO option is probally the easist and most economical. We are running one on the ChopZilla Hedging machine and it works great. The machine is amazing.

That has to do with pump displacement, not just setting a valve differently like for pressure.

Short answer: NO. You would have to replace the pump to do that.

Well i wouldnt mind replacing the pump, but what pump do i replace it with? Is it aftermarket piece?

That is the problem. The pumps are mounted directly to the engine and driven from gears, finding a larger pump that would bolt up would be next to impossible. Then you would need to know if the existing hoses/hardlines, and valves could take the extra flow...

There are no aftermarket solutions other than a PTO pump or a belt driven one of the engine-both would require another tank, filter, etc. Basically a seperate hydraulic system.

What are you trying to power?

Dwhit229,

If you are not using the PTO for anything, you can put as large a PTO pump as you tractor can support as in HP. Below pump, uses about 18.1 HP, and can pump 11.4 GPM
