Hydraulic chute rotation on front mount snowblower


Anyone here have any knowledge of hydraulics?  Other than hydraulic lifters and floor jacks?

 

I know I complain of being poor, and I am, but in spite of that, I went and bought a Kubota.  DOLLARS I know.  60 "easy" monthly payments that I hope run out before they bite me on the ass.   SWEET, turn the key, it starts, push the lever, whatever is supposed to happen, happens.    I'm still a Wheel Horse guy, had them for 35 years.   Guess that's it, had them for 35 years, and I don't care how good something is, it's a machine, and machines used regularly for 35 years are tired, and need TLC.    So after rebuilding the engine,   rebuilding the snowblower, restoring pretty much the entire tractor, on the first snowfall this year, the PTO clutch slipped!   Well, in a fit of rage as I've been working on getting this thing going for 2 years now............... I went and bought turnkey, on credit.  60 easy monthly payments.   The only other payment plan I have is the house, 360 easy monthly payments.   Not too crazy about about adding the second set of payments, but........

How the heck did I get so FAR off track??????????  I can see this is going to be a long post, but it's a cold day....

 

SO!

Front mount snowblower.  Sub compact tractor hydraulic system provides 6GPM with a max 1850PSI.  Loader valve, so two spools, joystick operation.   Kind of a long joystick at that, comes up, curves back a good foot to make it easy to reach.  One spool for up and down on the blower, the other doing nothing.

 

The hand crank for chute rotation SUCKS in my opinion.   It's clamped on the side of that long joystick control, so as I crank, if I'm trying to crank in a hurry because the wind changed and I'm turning into a Yeti, I tend to lift and lower the blower.   Like I said, SUCKS.

 

Kubota offers electric rotation for $400, hydraulic for $800+.  That's NUTS.

 

I know a lot of people have went the electric motor route, and I  know they've burned out motors before they got them waterproofed perfectly.  For me, on this particular tractor, there is no real handy place to mount the switch for the electric motor, HOWEVER, my hand rests on that joystick most of the time, with the side to side half not being used, so, logically, to me at least, hydraulic would be perfect.

 

Tired of reading yet?

 

SO, all I should need are, a small hydraulic motor, as little as $50 at Surplus Center.   Some restrictive 1/4" hoses to keep it from going to fast, connectors, build a simple bracket, hook it up to the shaft, and WALLA, hydraulic rotation for less than 1/4 of Kubota wants.  Right?  Probably not.

 

Odds are, I'll still need to add a flow control to set the motor speed.  I see two kinds.   One way restricted, full flow the other, and the other type is restricted both ways.  Would I need two, one way controls, one on each side of the motor, or would a single two way control be good enough?   Using the two way would mean, one way the motor was under little pressure as it would be downstream of the control, but the other way, the motor would be under higher pressure because of the control being down stream.   However, flow rate should be the same, so still control speed both ways.

 

Which is REQUIRED?  Which is more DESIRABLE?  I know which is more expensive.   The one way kind actually cost more, each, plus times 2.

 

Now, the motor has a "drain port available".   Uh, ok.   Does it need to be hooked up?  If so, where in the system would it go?  Back to the reservoir I assume? Assuming I can even tap into that.

 

Cylinders are SO much easier.   Just hook 'em up, and you're done.

HUH?????? I was lost at the word hydraulic,confuse Not much I can help you with,, we don't have snow ( hardly anyway) in Portland,, just the thawed out  liquid type

I did a little search tho, and found this  http://www.tractorbynet.com/forums/attachments/193960-mechanical-vs-hydraulic-snowblower.html  might help you some,, simple solution I think would just hunker down and wait till that white stuff melts,, biggrin

Thanks for the effort. That appears to be a discussion on hydraulic powered snowblowers. I just want a "simple" circuit to rotate the chute.

I do appreciate it though! Seems like my searches never turn up what I'm looking for, and for others it does. I know one guy in Ohio that seems to be able to find ANYTHING! Maybe I need to nudge him a little.

Now the funny part. I am a member the forum you came up with, but it's one of those seldom gone to forums. You know, the ones you join when you're really bored, but then seldom go back to?

As for hunkering down, I do it as much as possible!!!!!! One winter we didn't blow out the snow at all, I just kept packing it down. Come spring, Bobbi tried to go somewhere with her van on one of those first warmish days...... There was close to a foot of packed snow/ice that turned to a thick slushy. She got about half way out, got stuck, and it was several days before we were able to move her van again. That was our first winter together. The Wheel Horse was in storage, didn't have anywhere to put at her place, etc.... I had the old Wheel Horse going and moved into one of those tent garages for the next year.

Wish I could help Dale......and would love to have that Kubota. My snowblower is on a 44 year old MF10....the chute turns with a piece of wire on a bent rod ....She was working hard yesterday........lol

This is my 1985 ISEKI/Bolens 17Hp diesel with a crank chute. It's a floppy POS, but it does work just fine without worrying about more hydraulic lines to pop or motors to fry. I can and have been able to make repairs with anything from a 2 pound hammer to welding or a couple of crescent wrenches. Hydraulics was an option for moving the chute on the next bigger blower(60") and it was possible to be installed on this one(48"), but the dealer told me that they were not very reliable - being kinda Micky Mouse. A suggestion - a longer crank handle or maybe even a push-pull chute adjuster - and a LOT less expensive to build and maintain. And those payments - you have my sympathy.

Most of my work Wheel Horses are from the '70'as, so about 40 years old and have been good workers for me. I had rebuilt the engine in the one I was going to use for blowing snow, and not one to have anything stock....... It's first year was to be last year, but it refused to start in the cold. Being unable to track down the problem with fingers that don't work in the cold, I moved the snowblower, tires w/chains, and wheel weights to a different Horse for last winter.

Over the summer, I tracked the no start to............. get this, a dead battery. The starter circuit on the battery charger would spin it, but not fire it. So, I put a new battery in it. Just for good measure, I changed out the modified carb I'd spent 2 months on, for another, stock, but larger carb. Of course it decided to leak. I swapped out the inlet seat and valve a couple of times, messed around for a couple months, it leaked. So I put the modified carb back on.

Part of the modification was I removed the choke, and put on a primer bulb. Little hard starting, but I thought it would work ok.

Then I turned my attention to the snowblower. I installed a sprocket one tooth bigger on the auger drive to spin it faster, installed a taller chute, painted with graphite paint, ground all the stainless hardware down so it would have least impedance on flow through the chute, reworked the spring assist to work better, etc.

It had taken me TWO AND ONE HALF years, and countless bitch sessions about being tired of working stuff, BUT I was READY for winter.

Come the first real snowfall, I find the cotton picking primer bulb, which worked just fine last summer, so stiff in the cold it wouldn't work. Made the old girl kinda hard starting.

Once I got my 16HP Kohler that's jacked up to something north of 20HP started and warmed up, I headed into the snow. It wasn't going to take me long now! That's why I'd done all the modifications, to get the work done sooner instead of freezing.

10' later, the snowblower is at a dead stop, and I haven't even gotten to the first drift yet.

Backed it into the barn, spent half an hour trying to clean and refurbish the PTO clutch disk as best as I could with fingers that wouldn't work in the cold.

Out I go again.

5' farther than last time, snowblower is a dead stop.

Back into the barn, tear the clutch apart again. Work on it longer, I can see no reason why it should not hold!!!!!!! Put everything back together, fire her up.

5' farther into the snowbank............... yes, dead stop.

Backed it into the barn, and hobbled to the house.

I'd spent so much time bent over in the cold working on it, that I was flat on my back in bed for a couple days because of my back. That snowfall never did get cleared, just packed down. Ditto on the next one.

SO, now what? Still can't heat the shop in winter. Still can't really move enough to go do the blower/tires with chains/wheel weight swap thing again. STILL getting really tired of working on stuff.

Add that all up, and I now have a tractor that had better start, run, and work WITHOUT it being worked on. It has more horsepower, a wider snowblower, and does a pretty job of clearing the snow.

But, Kubota really screwed up the hand crank. They clamped it to the joy stick handle on the loader valve. Get to cranking away when the wind changes, and the snow is blowing in your face, the handle moves up and down as you spin the crank, and so does the blower. Who the H*LL designed that???? That handle controls 2 spools, one of which is doing nothing..... seems to me a hydraulic rotor is in order.

Yes, up to a point.    Heck, I'm already planning changes to the NEW equipment.   It's just when I've done something 8 times, and it still doesn't work, especially when it's something I've done a dozen times and never had any trouble.........

 

I've been saying for a couple years, "I'm tired of work on sh*t, I'm going to go buy something where I can turn the key and go."   I guess it all just came to a head.   I've wanted one for a long time, had some money saved up for a new garage, which would probably have went for a new roof, but wound up being the down payment............   My biggest worry now is, the house roof surviving long enough to save up enough to pay for it.

 

So much for that new garage, with a concrete floor instead of a crooked OSB floor, and a roof that didn't leak.  Back to whatever tar patches I can slap on the barn roof.   Life, huh?
