While cruising this great forum I came across a discussion about front hydraulic snowblowers - biggest issue for smaller tractors being the lack of gpm at the pump to even consider such an option.
Then along comes this company: Sheyenne Tooling & Manufacturing - Compact Tractor Snowblower
And they have a pump that runs off of the tractor pto (their preference is a mid pto running at 2000rpm but have an option for a rear pto where they step it up to 2000) and they supposedly T into the hydraulic system for fluid supply.
Leave out comments about it'll over-heat (they say it doesn't given typical temps when blowing snow) or any other comments.
My question is:
How can you T into the hydraulic system in the first place? (Obviously they are doing it successfully - I'm trying to understand how - I've plumbed my own grapple, plumbed my own set of 3 rear remotes so I've got a good idea of how a typical tractor hydraulics work and in my understanding as soon as you have one valve open everything downstream basically is not going to work yet they are blowing snow and running the loader at the same time? How they do that?
I'm thinking they are doing an actual T in the high pressure line going to the loader valve? And then dumping back into the tank at the other end. By doing a T in that line going to the loader valve would that keep the loader valve (and anything else downstream) still operational while the blower pump is running?
Or would they have to T into the line that is feeding the tractor hydraulic pump(s)?
