Running electric splitters off a tractor - Is it possible?

[arboriculturist]

Has anyone out there experience of connecting 2x 7 tonne electric splitters to a 35HP tractor with a max flow rate of 20 ltrs/min at PTO speed?

 

I accept specific hydraulic regulators may need to be purchased etc.

 

The tractor is fitted with a pair quick release hydraulic couplings already.

Or get a PTO genny.

The reason to run off tractor is to increase the flow rate to rams on splitter as just painfully slow as they are. Disconnecting existing splitter pumps completely.

Well you are going to need a tandem pump, one circuit for each splitter but that's the least of your problems

 

The existing ram and pipework will be matched to the pump so speeding up the cycle time might not be as simple as chucking a load more oil at the problem.

 

What's the specification on the existing set up

[arboriculturist]

Sorry, we were considering using the existing tractor hydraulics to run 1 or 2 splitters.

 

Planned to scrap the existing pipework and just keep the spool valves on the splitters.

 

I would need to check the spec on the existing pumps on the 2 splitters - they are v small though.

Don't they suck some pto power tho...

If you run them on the existing valves with a single supply you will only be able to operate one at a time unless you fit a flow divider, even then you will only get 10l/min per unit, is that enough?

Poster called 'JUSTME' - thought I wanted to keep the 2 splitters electric - No we want to disconnect existing electric splitter's electric motors and pumps and run new 1/2" pipework direct from tractor hydraulics to splitters spool valves.

depending on whether the two oil reservoirs can share oil there may be no need to disconnect pump. Will the valves, pipes and rams cope with the extra flow?

The splitters are actually rated at as high a psi as the tractor will produce having tested its output.

 

Easier to connect to spool valves on both splitters in this instance and use tractors relatively large hyd oil sump.

 

I expect to hear from Treequip again on the topic, as for sure he consistently gives great advice. May be a futile excercise but that is why I posted initially.
