Increase hydraulic GPM for attachment

[Kevin h]

I have a L5030 and wish to operate a auger bucket for mixing cement. the mixer requires 14.9 GPM and the implement pump on the tractor is rated at 9.7. Can a different pump be changed out that will increase the GPM?

 

[hodge]

Probably not (I could be wrong- if so, someone correct me).
What about an external pump, run by the PTO?

Kevin - - I'm going to take a guess that the answer is no, not easily.

While your pump is rated 9.7, I think it's a 2 section pump and part of that (about 50%) is for the hydrostatic steering.

If you could jack that OEM pump to something much more, then you could have issues with the cooling system with a higher-rated gpm...would it keep up and create an overheat problem?

The other option is a PTO-driven hydraulic pump, but there are concerns with cooling, storage/tank capacities, etc.

Again, I'm making guesses here. Don't take it as gospel.

PS - - Hodge beat me to it.

I should've looked first at Tractordata.com:

http://www.tractordata.com/farm-tractors/001/8/5/1855-kubota-l5030.html

Valves: 3 optional
Pump flow: 9.8 gpm [37.1 lpm]
Total flow: 14.7 gpm [55.6 lpm]
Steering flow: 4.9 gpm [18.5 lpm]


So, you have 9.8gpm after steering....will it run, but slower.?.?.?.don't know, but a question to ask. I would still be concerned with heat....

Nope can't do it.

But as others have said you could do it with a PTO driven power pack, but they ain't cheap!

What about changing the motor on the mixer instead? You may lose some torque, so mix a little smaller batches. Would be a lot cheaper and easier than messing with the tractor.

Just my two cents.

Wolfman is correct, a power pack would solve the issue, but they can be expensive . I just am completing a shop built model but I wanted 32 gpm from my 540 pto. Cost would-be significantly less if the requirements are <20 gpm. You would use FEL to support the mixer, pto would occupy the pump . Heat not so much an issue as you mix then pour, there would be a pause in pump operation.
If mixer is front mounted, better to locate reservoir closer to pump. Would need a frame w/pins for 3 point mount for reservoir. Mount mixer bucket to FEL as you describe. . You have QA, . Or a SSQA mixer? For FEL.

My unit will run constantly, so I added a hyd cooler w/fan . PTO can serve as a valve but frequent pto on-off is not advised.
Here is a basic ballpark recipe:
Pump, generic Not prince price level. $300 (dynamic) alum center
Reservoir $250 25 gal.
Filter assembly $40
Valve $85
Pressure reg $80
Hoses/fittings $300 1/2" pressure supply/return, could be more $ +/-
Shipping -$80+ support reservoir frame 3 point $100 ?

Mine was quite a bit more do to gpm capacity. PTO speed increaser $1,000. + the pump $400
Custom 50gal reservoir $1,000. W/ frame, Cooler w/ fan $500. Pressure hoses 1 inch. + stuff above increased for 1" pressure lines.


PTO pump is maxed out at 20 +/- gpm driven by 540 shaft. A speed increaser is required if greater output is desired from 540 rpm. Engine hp evaluation is a consideration for higher GPM output. As PTO speed is increased by gear device, engine torque is decreased.

Where did you find the speed increaser? I’m building a power pack to run a skid steer snowblower off the tractor. I can’t seem to find a speed increaser anywhere. I am basically trying to recreate the Erskine HP20 but can’t for the life of me figure out what pump or increaser to use. Blower needs about 18-21 gpm at around 3000 psi.

Have to ask ,just how big is the 'bucket' ? The commercial mixers I see(motar mixers) use 9HP Honda's with 6:1 reduction units on them. Having a 'stand alone' mixer seems 'right' to me,easy to move(could be SSQAed),easy to use, and 'clean'. One mtd on a tractor ,esp. with hoses could have problems...
Nuther Q, is how often are you going to use it ? Small jobs(posts) or big jobs( floors).
if you do go as originally planned, the PTO pump(with relief and valving and hoses) seems the only choice. BTW how FAST can you disengage the PTO when a hose breaks ?
Jes trying to think of 'options'.....

What kind of mixer is it? I have several hundred bags through my setup on the B2650 with much lower GPM (about 5). I am using the auger motor (I use to drill with) to spin the drum. Just a hair above engine idle, I get 33drum RPM. This is using the factory 3rd function. I also added wireless remote control to the setup. Mix clockwise, pour CCW. Mix on one side of the yard, deliver and pour it on the other side of the yard. It works great.I can mix 3 bags in the current setup. The tractor/setup could easily handle 4 bags if the drum was a little bigger.
