I am looking to run a drive motor on the FEL of my 2020 L2501 using a 3rd function valve kit from my power beyond port. The motor is specd for 7-18 GPM up to 3000 PSI. The hydraulic flow rate of my tractor as I understand it is 5.15 GPM. Is there any way to upgrade the pump to get a little extra flow here? If I use shims to bump up the pressure, would that also bump the flow a little? The other option would be a PTO pack but trying to avoid that if possible. Thanks in advance for the help!
Upgrade options for L2501 aux hydraulics?
- Thread starter Helix
- Start date
What is this motor going to be powering? There isn't going to be an economical way to get that much more flow, more flow is more displacement. Plus that motor wanting 7-18GPM, it will perform marginally at its task with 7gpm anyway. An additional 1000psi of hydraulic pressure, you also risk damage to the rest of the tractor's system.

I think you have to go with a PTO pump or spend a lot of money making some other pump fit and then work correctly with your hydraulics the rest of the time.
It would be a drive motor for screwpiles. So a low rpm high torque auger type motor. I'm OK with the standard 2250psi that the machine is equipped at. It will generate the torque I need. Just looking to get a feel for what it would take to bump up the flow rate, if it can be. Thanks again. Here is the gpm to rpm of the motor chart. I have no issue with 6 RPM, this will be suitable for my use.
Unless you're driving those screw anchors into relatively rock-free, sandy soil, the substantial torque increase even going up 1-2GPM would be significant when dealing with clay and heavily compacted soils.

There is no simple pump upgrade.
Upping pressure lowers flow it doesn't raise it.
5.1GPM on a motor thats min is 7 GPM, you'll get about 100psi and 1 rpm out of it.
That is if it will turn at all.
Simply put, you will need a power pack to run it.
You're looking at about $2500 for the power pack.
Or get a skid steer or track loader!

let me throw another type of spanner into your gear set over and above flow rate......
The L2501 has pretty spindly loader arms. Are you not worried about the forces of installing screw piles on the potential damage?

I'm not too concerned with this small of a drive. They are designed for light mini excavators and walk behind skid steers. I've had the L2501 for 5 years now and if anything it has always seemed overbuilt for the power it has. Thanks for mentioning though.
Interested to see what the results are and how much time it takes to fully drive an anchor into the ground. Post pictures/video!

Your tractor has a fixed displacement gear punp. Changing relief pressure has no effect on flow rate. Increasing pressure will increase motor torque.

I was referencing the screenshot OP posted showing motor input/output. My comment was meant to suggest that going up to a reasonable GPM from a power pack, larger machine, etc. would substantially help him drive the anchors in the ground.
