rtv900 hydraulic specs (2008 worksite)

Does anyone have the specs for the hydraulic pto on the 900 worksite model? I know that there is one pump that supplies both the dump and the hydraulic utility connections. And I understand that the flow is 5gpm. But what is the pressure?

I am trying to figure out if I can use the hydraulic system to power my snowblower (currently powered by a 31hp Vanguard gasoline engine with belt and pulley and clutch system). But I need to know the specs of the hydraulic system to see if I can get the power and rpms that are needed to run the 2 stage, 60" snowblower.

This is way outside of my tech skills, but a qualified friend has expressed interest in helping me set it up. But we need specs to know where--and if--to begin.

Thanks for the help, guys!
 
You will be way low on flow for running a motor like needed for a snowblower. Also you would need a cooler with good size as even in cold temps you would generate a lot of heat. Look at the specs for a skidsteer snowblower for an idea of gpm and flow needed. The reservoir on the rtv is also very small compared to a skid or tractor.
 
Muleman is right.Some info I have off of a Kubota CD also said that the earlier RTV 's reservoir were too small and would overheat with constant use - . I have heard that some even melted. You might look at the optional implements for the RTV on the kubota site and get an idea of what they are meant for - I think only for -maybe a cylinder up and down or maybe a small log splitter. I had wanted to get a fancy weed wiper with a hydraulic powered applicator but learned after research that the RTV wouldn't handle the hydraulic motor and that I would have to buy a hydraulic power unit with a gas motor for that particular wiper. I dropped that idea and got the basic one . Good Luck! Bordercollie
 
Thanks, Muleman and Bordercollie. Your observations are borne out by my research. I learned that the hydraulic system yields about 6 US gpm at 2200psi, which at 85% efficiency is less than 7hp. Not nearly enough to drive the snowblower.

So I am stuck with depending on the gasoline engine to power the blower, which works OK, but only with a lot of fiddling. And I really don't like the belt drive setup. So maybe I can use the Vanguard engine to power hydraulics to run the blower... Need to think about that. Sigh.

Thanks, guys!
