Hey all! Im looking at getting an old snowblower for my Case 540 and found 2 interesting SB, both 6' wide but one has the auger driven by an axle (differential type like on a pickup truck), and the other one is chain driven. The axle one is way cheaper but Im wondering how these perform and how reliable they are ? I assume as its an axle it must be pretty tough but at the same time they dont make them that way nowadays must be a reason ? Anyone here got some experience with the axle type or both and can tell me the pros and cons ? Thanks guys !

Sure would like to see a picture of what you call axle driven. My 48 2 stage is directly driven from a gear box. Most chain drives I've seen, have a sprocket on the end of the auger but still use a gear box and shaft to drive the chain. Are they both 2 stage?
Yes both are 2 stages. By axle I mean the auger is driven by a differential in the center of the SB. The PTO shaft drive the fan and goes straight into the differential, with the auger on both side of it. Only cons I can see is that because of the differential housing in the middle, it might reduce snow intake and create more restrictions as it will compress on snow going thru a snow bank. Heres a picture of the kind of SB im talking about.

The problem I see if it is truly a differential is if taking a half cut the one side with the load stops then the easy one turns. I would hold one side then try turning one side and see if it is a true differential. If so I would let it slid by. get the one with a chain.

That would not be a differential in that application. J.ust a right-angle drive so both sides turn in the same direction. Mine is chain drive so I can't comment on how well it will work. Reason? Chain drive would be a lower cost to manufacture.
As others say, that should be just a gearbox, not a differential. Wouldnt work if it were a differential.
I assume it costs more for a big gearbox like that. With chain drive they can use a smaller gearbox cheaper. Is why that isnt done any more? Never seen one of those, so cant say how it would work.

I would rather have that than a chain drive.
Well it's probably like tillers...used to be worm drive with cast iron housings. Then the economists took over and it became chain drive with 2 pieces of stamped steel.....they tried that with riding mower front axles.....that was a total flop and only lasted a couple of years.
I cannot see that working in heavy snow without pluging, Perhaps for snow 6 or less might work. But not in 2 feet of snow. Did not even realize they made something like that. Back on the farm neighbor friend reletave would blow me out with I am guessing a 150 HP front wheel assist tractor and I would see him setting with all 4 wheels spinning trying to push into the snow and I do know his was a chain drive. I cannot see that one with the obstruction in the middle working here.
