Hydraulic snowcaster

Howdy guys. (more specifically all the hydro gurus out there) :howdy:

It is getting near the end of summer, and I am re-visitting a idea of mine.

As most of you know, I have mounted my snowcaster on the back of my tractor and i have been driving the unit with a B&S 11 HP. This concept works very good. But.

I was always planning to put a Hydraulic motor on this snowcaster at some point. (This point and time is now)

So this brings me to this question. (and this is where I wish i had the help of some ""very knowledgeable hydraulic guys"")

If I were to use a .58 Cu. In. Gerotor motor to turn the jackshaft on my snowcaster at its top rated speed of 5000 rpm at 15 GPM, would this give me enough torque to "compare to" a 11 HP B&S engine?

Here is a link of the specs on the motor in question?

What do you guys think?

How many GPM does my 224 deliver? and if less than 15 will this reduce the torque in question of 184 In. Lb.

:eek:mg: Here I am again, asking more questions than i can handle. :fing32:

Thanks again for any help fellas, I appreciate all inputs.

BTW, My 224 is going on its, 4th year with the loader and 2nd year with the blower on the back and all is well with the frame. No evidence of stress on the frame. (I do believe the 200 series are strudier frames) :dunno:

Anyways, what say you, does 184 In. Lb. of torque compare to a 11 B&S turning at 3600 RPM?

I like your idea of replacing the engine driven rear mounted snowblower with hydraulic drive, especially with the front loader setup you have. The 38" model blower would require less HP. to operate than the 48" models. Your 224 produces about 8 gpm flow and that equates to about 10 to 12 HP. through the hydraulics. Given the fact that you have the loader to operate and also need power to move the tractor, I think you will end up on the short end of available power to run everything, but I could be wrong. I don't think the motor you are looking at is the right choice for this application. Do the hydraulic formula using 8 gpm. @ 3,600 rpm. to achieve an auger speed of about 900 rpm. or 1/3 engine speed. I know of several guys that have converted their blowers to hydraulic drive but they had the 18 to 20 HP. Onans. The Ingersoll All Hydraulic 3100/4100 series in the early 1990's used a hydraulic driven blower but they had higher gpm. pump output. I will try to find the information on the hydraulic motor used on the conversions if you are interested. Again, I hope you follow through on this project and it works well.

The hydraulic motor used in a few of the conversions is a Haldex # 4F657 or 4F658. Here is a link : ...

I suggest you obtain a performance curve on the Parker pump to see where it is going to perform at using the gpm & rpm you intend to run it at ... You already know the intended flow is less than 50% of their listed spec's so I would presume the torque listed is going to be substantially less also. That information should be free from Princess Auto...

Sounds like a plan. How are you going to plumb the hydraulic motor into the system and control the on/off flow ?
