MF 240 Aux Hydraulic question

[MoDeer43]

I have a MF240 and am looking to add an aux hydraulic system to increase
what I can do with it. I have seen complete kits for both single and double spool kits, but am not sure what the difference is ? I am new to the tractor world so any help is most appreciated.

The single spoll kit list for around $350, is this a good price ?

Thanks for the help

Your pump flow is 4.2 GPM

JJ,
I understand the flow that my pump has,and the one in the link say 8.5gpm.so is my smaller flow rate adequate ?
I really dont understand the differene between a single spool and twin spool system? What are the specific benefits of each ?

Thanks

A single spool valve allows one the ability to control a cyl circuit or motor, and two spool valve just allows one to control two circuits.

T-N-T is an is an example, one spool to control the top cyl, and the other spool to control the tilt cyl.

One spool valve

Two spool valve

If I put a deverter on a MF 240 to run a hydraulic remote set, can i switch between the 3 pt and a hydraulic cylinder? I am looking a buying a turbo saw.

If you want to run a turbo saw using a remote valve, then you need a single spool valve with PB.

If you need to run a separate cyl, then you need a two spool valve.

If you have a FEL now, and it has PB, then you run a hose from the FEL PB to the IN port of the new remote valve.

If you do not have FEL, then the pump flow will go to the new valve first.

If running a hyd motor, then you also need a motor spool valve with detent.

You can still use the 3pt, but only if the saw is not running. The saw will take all or most of the fluid.

Set the 3pt first and then activate the saw.

Thanks for the help.

The tractor has no FEL. The saw runs off the PTO, so if I set the height of the 3 PT first, switch the deverter to the cylinder, the 3 pt should stay at the same height, while the cylinder is in use?

Thanks again.

I thought the turbo saw was hyd motor powered.

You want to break into the line from the pump to the 3pt to add a remote valve.

Just insert the valve in series with the pump flow, and you still need PB to pass the fluid downstream to the 3pt.

The 1/4 in plug goes inside the PB port for PB operation. Use some Loctite red or blue on the 1/4 in screw.

On a MF does the 3 pt have to be in the full up position for the pump to flow to the remotes?

 

[J_J]

You should be in neutral. If not, then you are either raising or lowering the 3pt. The 3pt should stay where you left it.

In an open center hyd system, the pump fluid is always flowing somewhere, and if all valves are in neutral, the fluid just passes through all valves to tank.
