PTO Hydraulic Pumps

IAtractorKid · Dec 17, 2011

Anyone using a PTO hydraulic pump to run a loader here? Been looking at getting a 17 or even a 23GPM PTO pump to run a Koyker SuperK loader on a Farmall M. I noticed the pump listings say the resvoir should be at least as large as the capacity...I'm guessing the reduce heat? Wondering if anyone actually follows this or not? The Koyker loader has a built in reservoir but I can imagine its over 10 gallons if even that much. Am I really going to need another seperate tank and a full 23 gallons of fluid? That seems excessive for no more than I am looking to do (plow snow...light loader use).

I am running a 23 gpm pump on my Farmhand loader. I think it has a 5 gallon reservoir. As far as I know that is all the bigger Farmhand ever sent out new, and they almost always had the big pumps. The DUAL loader that my dad had, had the reservoir in the left upright, and I think it held about 7 gallons. In my opinion, go with the big pump, and don't get to worried about the reservoir size.

I have an Oilver 88 with a Farmhand loader and a pto pump and the pto is live. I will never have another pto pump as it ties up the pto! I also have a Farmal M with a loader that has a belt driven hyd. pump that came from a model 95 John Deere combime and it works great! It gets it power from the front of the crankshaft and the pump has a dedicated 3/8" in. pressure outlet for the power steering as well as the 1/2" outlet for all the other hyd. needs. As for hyd. oil cap. I would prefer 5 gal too much over 1 pint not enough! Go with hyd on the M and you will never regret it! Use it and enjoy! Armand

The tank on your loader will work just fine; it was designed for that loader's operation.

Get the 23-gpm pump. Just flat makes things "nice". :>)

If the hydraulic system is set up for double action, easy spotting is hose at each end of the loader cylinders, then all you need is big pump for fast action, all that is happening is oil is transferring from one side of cyl to other. If its single then you will need a large reservoir.

Hey,I have always wondered if a combine pump would work-if they had enough pressure or volume.So you would say yes?I have a couple old combine pumps around here.

Use the pump you have then if you want faster lift you can always go to a bigger pump later.We used loader on the M for years with front blade pushed lots of snow had a 1/4mi land then another 1/2mi to get to two cattle barns.

Worked for 25 years in the engineering experimental lab of a hydraulics company. Part of my job was to modify customer machines for our systems. Rule of thumb was the reservoir on mobile hydraulics should be a minumum of 1/3 the pump capacity in gpm. Most later high pressure systems has a cooling system built in, like a radiator in front of the engine cooling radiator, but lower pressure systems used the surface of the lines and reservoir to cool them. Mainly hydrostat systems needed the extra cooling. Your loader frame along with lines should be sufficient.

Except for extreme continuious operating situations which generate excess heat, a tank capacity of 1/4 to 1/3 the gpm capacity of the pump should be sufficient. A 5 or 6 gallon tank is good on the 17 gpm and a 6 to 8 gallon tank whould be plenty large for the 23 gpm pump in your application.

I doubt it Steve. Remember on a loader you have TWO cylinders working and they are usually fairly large bore. It takes a lot of oil volume to move them. The original H & M belly pump is fairly large volume but it's low pressure and not all that swell if you want to lift anything heavy.

IH fan · Dec 17, 2011

I think most, if not all, Koyker loaders are double acting, so a high percentage of your volume will return to the bearing end of your cylinder... only the volume of the rods will need to be stored in the reservoir. My loader has 4 double acting cylinders, has a crankshaft driven pump and the reservoir is in the frame of the loader... no problem.

I have a 1952 Farmall "H" with an old cable over hydraulic 2 cylinder loader. I needed to lift the end of a 12 x 24 building and the belly pump wouldn't do it, so I took it out and shimmed the pressure relief spring and it will lift anything I want. Just loaded my 5 foot bush hog onto a truck just last week. Just wish it was "Live".
