If I'm not mistaken, I believe GRS has the supplied auxillary pump and tank for the blower that's supposed to be sized appropriately for it.
Could be wrong though.
Again, I almost purchased one and much earlier this year, I pm'd GRS about where he got his attachments and procured a catalog myself. I considered the 'Power Pack' option too. That way, the hydtaulics to power an attachment are independent of the tractor hydraulics, no chance of cross contamination of fluid and the pack can be used for anything hydraulically powered, not just their attachments.
I did buy a couple non powered attachments including a front mount QA Plate hay spear. Everything I purchased is of very high quality both in finish and execution.
The company that built his blower sells direct to the end user instead of through a retail outlet
I don't care for the lack of torque in the impeller drive, something isn't set right. The input auger's sole responsibility is to chew through snow pack, break it up and move it toward the fan, not quit turning.
I didn't really observe the tractor engine being loaded down with hydraulic pressure head in the video, something that you should hear and the operator should feel..... something is fishy...
