I have a 1978 Case 444 tractor, S/N 9753783. I want to adapt a Gravely 2 stage snow blower to run with my tractor by powering the snow blower with a hydraulic motor. In order to size the motor so it spins at the right speed I need to know what flow the pump on the 444 produces.

From what I've been able to find in parts manuals it looks like the pump is a Parker Hannifin that Case gives the part number C17300.

Does anyone know if this is the correct pump for my tractor and serial number and what flow this pump produces at what rpm?

Thanks,
Rick444

Flow for 444 is 8.5 g,m  prior to s/n 9677449 and 9.5 g,m for s/n 9677449 and that is one of the pumps they used.

For a brief period Ingersoll made an "All Hydraulic" model meaning the implements, including AH Snowcaster i believe.  The AH didn't last very long, more complex and not as a reliable as the regular belt driven stuff.  That is just my understanding, i could be wrong.

 

Anyway the plain old Case snow caster is one of the best available of any era.  Lighter than a 2-stage, more simple, very rugged, and all rebuild parts are available reasonable through Ingersoll or some even ebay or the hardware store. 

 

When set up right they can blow any type of snow almost as far as an average 2-stage with a lot less hassle, less clogging, etc.  You can run the standard 48" on a 444, or a 38," and can even add some inexpensive wings from Ingersoll to make it 42" if that works better for your storm patterns.  Some people even adapt a taller JD chute to throw farther i believe.  Again that is just my opinion, good luck with your project

Hi gopher,

Do you know what rpm the pump is spinning to deliver the 9.5 gpm for the later model pump that Case used?

Thanks.
