Wisconsin powered FEL snowblower.....

[linrick1]

Hello all. I am in the midst of purchasing a 64" Puma 3 pt. snowblower and already am determing how to convert it to a hydraulic drive Q.T. FEL mount. The plan is to build a 3 pt engine/pump/tank arrangement, hose run down the loader arms, hydraulic motor and Q.T. mods to the blower. I want to use a Wisconsin V4 to run the pump, for no other reason than I want a V4 to go along with the THD on my old Lincoln welder and this is as good an excuse as any - I love the old Wisconsins....anyway, I would hang all this on our Ford 1900 which is a gear drive rig and this would allow me to drive the tractor with the foot throttle without affecting power available at the snowblower....plus, a 60 horse 5' snowblower, overdriven a bit, really ought to throw some snow.....Overkill? Absolutely, Practical? Maybe not so much but I want to build it regardless..Love to hear pump/motor control suggestions, sorry bout the longwinded post, thanks, Rick

A few questions:
1) Where are you going to mount the engine, reservoir, etc.
2) Types of controls: Will you have hydraulic chute rotation and spout. Will these be run off of the tractor hydraulics or the Wisconsin motor?
3) What RPM was the blower designed to operate at? Presume 540 PTO

Not sure if practical but could you use a clutch / belt reducer and direct drive the blower with the V4? Would be far more efficient than hydraulics and potentially less expensive. Would have to mount the motor on the blower frame so it moves with the FEL for this to work.

Ball park numbers:
to generate 50 hydraulic HP at 540 RPM requires approx 32 GPM @ 2500 PSI. This is a 14 cubic inch per rev motor. This does NOT take into account system efficiency.

Did you look at the vid that was posted on TBN and also look at You Tube there are some there that I was looking at. It seems from my observations that the front mount loader system is power hungry.

Exactly, hydraulic drive is common on skid loaders because they don't have PTO shafts and the pumps are built in.

Hydraulic drive would be beneficial if they are anticipating doing a lot of drift cutting where being able to raise the blower several feet off the ground would save knocking down the drifts.

If possible, I would hook the engine directly up to the snowblower and mount the whole assembly to the loader. (Kind of like how the big payloader snowblowers work, only smaller.) That way you don't have to worry about hosing, filters, power loss through the hydraulics, etc.

Found an example: SnoGo Snow Blowers | Wausau-Everest Brands | Wausau Everest

Part of the reasoning for not mounting the engine forward on the blower is to balance the weight distribution. The combined weight of the engine and the blower is almost at the lift capacity of the tractor. We have an early 80's Ford 1900, 27 hp at the pto and is an all gear drivetrain. We have already had trouble with the front axle and I am leery of hanging a bunch of weight out front, especially since I have to deal with some serious hills.
The plan would be to fabricate a very stout L shaped tank, with the motor/pump sitting transverse in the crook of the L, set up to mount on the tph. That should weigh somewhere around 700 lbs, and even some of the blower load out. The blower is rated to 50 horse and I only have 27 at the pto, the Wisc. will give around 60 horse for the pump so with system loss I should still have considerably more hp at the blower than I would get if I left it rear mount...just thinking out loud..... all ideas appreciated...Rick

Rick,
an option might be to look at hydrostatic units. These will run closed loop and do not require as large of a reservoir as an open loop system. The controls would be but simpler and if components are speced properly pressure could go to 5000 PSI so flow rates and hose sizes drop significantly.

I don't know what type of hydraulic experience or dealers you have in your area but I would think you could get a pump motor combination that would meet your requirements.

Not sure what RPM the Wisconsin V$ runs at for example purposes I will use 2400 RPM

Motor size: 7 CIR (cubic inch per revolution) at 5000 PSI is approx 50 HP

7 CIR @ 600 RPM = 18 GPM flow required for motor

Pump Size: 2 CIR @ 2400 RPM = 20.78 GPM

20.78 GPM @ 5000 PSI = 70 HP @ 85% efficiency

This does not include any charge pump HP

A word of caution or advice. Consider some form of run down/ deceleration control for the motor to prevent pressure spikes from the blower trying to stop on a dime.
I hope these numbers give you some ideas an how to start sizing components.

If proper components are selected you could also use the charge pump flow to control the blower chute functions.

If you get real lucky you might be able to find used or rebuilt components from skid steer or similar piece of equipment.

Sauer Danfoss AKA Sauer Sundstrand and Eaton Corp are probably the two most common sources here in the US that would make units in this size range.

I will have to find it, but a guy at another forum did almost exactly what you are describing with a Farmall Cub. He built a frame under the tractor, mounted a large gas engine to it, then used that to drive the snow blower out front. I saw it demonstrated at a get together in Ohio. Rick Prentice was the gentlemans name that did it.

If you go to the Forums over at FarmallCub.Com there are lots of threads about folks building these.

If it's a V65D don't you think that's slight overkill ? Thing must weigh 3-400 pounds. Does it have a Rockwell PTO? I'll trade you my brand new freshly rebuilt VG4 for it!

Hey all, thanks for the comments. Roy, I've worked on a lot of different hydraulics, but nothing involving the design of a system of this sort so your help here is invaluable.

Can you clarify the differences between a hydrostatic and hydraulic system for me? If I understand correctly the hydrostatic uses a constant pressure and volume and alters the "pitch" (for lack of a better word) of the motor to vary motor output........

Close? Not close at all? What would I need for motor/pump/control system and are the component prices more expensive?
Thanks again
