Third Function flow rate

Tul01 · Apr 7, 2015

I think I've read almost every post on third function set ups and uses. I would say that I am finally starting to grasp some of the info. I would like to put a hyd auger on the bucket of our tractor. I have 2 questions first I think is obvious, but to confirm if I set up a 3rd function on my loader curl circuit, when it is diverted to the auger, one direction on the lever is one way and the other way would reverse the direction right? And in doing so I can feather it the same as controlling bucket speed? Second bigger question is flow rate. I see the valves and their ratings, so I know I can select a valve that matches, but how do I know what the rate is in my lines on my loader? I am rated 18 gpm at the rear scv. The auger I am looking at is rated 15-30gpm, so I am at the lower end of the motor speed anyway, I don't want to compromise it further if the loader lines will not flow as much as running 1/2" lines from the rear.

Thanks

Your loader will have the same flow rating or should as the rear remotes. Double check that the QDs on the loader are 1/2" and that all the loader lines are at least 1/2". But then you have the real problem, none of your 1/2" AG style couplers are going to flow your rated 18GPM. You may need to change over to either 5/8" AG style or 1/2" flat face couplers. I personally would start out just using the std AG type 1/2" couplers and see how that goes. If you are not satisfied with that, then change out the couplers.

The other option is to look at a smaller GPM auger and not worry about all this other stuff.

Just my :2cents: Good luck

Are you planning on sitting there and holding the FEL lever for the auger the whole time.

You might also want down pressure using the lift lever, so the flow will be divided.

Your valve might have regen, so that is something to take into consideration.

Are you going to always run the engine at max. The GPM is directly related to engine speed.

The hose thing is not really a big deal.

If you are really concerned about the flow rate, do a flow and pressure test .

Thanks guys, I would be getting a good deal on this big auger as it is left over stock, so I'm getting a bit greedy on the size I know.

If I went with lines from the rear, wouldn't down pressure on the loader steal from there as well?

I hadn't really thought of the comfort aspect of keeping the loader valve kicked over to the side (probably hard on the forearm?) maybe I will just go with hoses, I'm familiar with monitoring them/keeping pressure on them.

JJ I have built a pressure meter from one of your other posts

is there reasonable cost flow meters out there, the only ones I came up with on a quick search are $800, too much for my curiosity. Thanks

I have installed a 3rd function remote for a hydraulic PHD on my tractor. I haven't received the PHD unit yet as I only ordered it yesterday. I debated about the unit at length and finally decided to go ahead and get it. The auger itself is controlled by 2 thumb buttons on the loader knob and down pressure and curl applied by the loader control arm. I don't anticipate any issues with applying pressure to the curl and down pressure at I have used a bucket loader for many years and the physical force required is minimal. If you review the attachments forum and check the posts about hydraulic loader PHD most a very positive about how much better they perform than the PTO versions.

Not sure what it is that you will be drilling through, but I can drill an 18" hole 48" deep through decomposed granite that the water evaporates faster than it soaks in, in less than 3 minutes. You should be able to run the auger and put down pressure at the same time with your loader. If you go to the rear remotes for your auger power, now you will have both of your hands busy on your right side. That seems like it would be real comfortable.

Good luck with your decisions.

Yes, there are cheaper flow meters, just have to search the internet. Amazon, Ebay, Baileynet.com, Surplus Hydraulics, etc

You probably only need less than a 15 GPM flow meter.

Unless your hyd is first in the series flow path, anything in front will steal flow.

You could put some serious weight in the bucket and not have to use much down pressure. .

A true 3rd function solenoid motor valve will let you flip a switch and lock the motor on and it will run full speed, based on your engine speed. If you use down pressure, you reduce the speed of the auger, depending on the lever control..

Ok thanks all for the help. Just got in from doing some work and my loader seems to have float(regen?) on both tilt and lift, or is this just float as most people are referring to it. Never use it for anything. Maybe I should try next winter pushing snow. Learn something every day :thumbsup:.
