Outdoor Power Equipment (Lawn Mowers, Snow Blowers, Chain Saws and more) Discussions

Iwas looking on You Tube and ran across a snowblower I've never seen before. I know nothing about putting links on here but if you go to your favorite search engine and type in Wisconsin Engineering SF 1330 you find this blower. It's a tank but expensive. Maybe you guys have seen it before. What do you think?  Glen from Minnesota

A hydrostatic transmission actually has very high parasitic losses when compared to a mechanical drive. You'd have less available power for the blower head in that case. This particular transmission is scooped straight out of lawn and garden applications. No special accommodations for winter weather, not even 0W synthetic hydrostatic oil. It'll be a 'tank' if you only blow snow above 30 or 40 degrees.

I'm familiar with this unit and have operated them. Not impressed given what they're asking for it, and 30' throwing distance is dismal for such a machine. Needs an industrial stylist and more 'finished' engineering and manufacturing process (looks like it was manufactured with very basic means).

On the plus side, the electric clutch is smooth and silent. The intent of the ratcheting gear case overload protection is also good (no shear bolts), but I wonder how long it would hold up.

I believe this outfit started out in Sheboygan, WI, hence the name.

Hydrostatic or hydrodynamic?    Cars are hydrodynamic, and you lose a ton of power through the torque converter.  Hydro lawn equipment don't have this.  There may be loss from the hoses ect.  but I definately know that it won't slip like a wet belt, or the slip-o-matic in my Ariens snowblower.  Theres a ton of power loss coming on both ends of that beast.  Not easy to work on, that much is true.  But its real power, that's why heavy equipment (which is already running a pump so I guess it makes more sense) uses it, and its VERY reliable. 

I say we put in a pump for the auger as well, that way in the spring I can get double use from it as a wood chipper!

Short hoses hose would mean low loss, and a cold enviroment would mean less loss through fluid expansion.  Weight is not really an issue, its not like we're displacing freight in leiu of hydraulic fluid.  I think the loss in power would me more than made up in the direct transfer of power to wheels instead of a friction disc.  Smooth like butta.
