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

I here from many that  Ariens track drives do not have steering. They say that they have differentials that can lock both tracks for better traction. If I unlock the right side then just the left will be driving. To me that is confusing because if the left is driving then the unit will want to go right . So what is the differential doing? What is its purpose. I thought differentials switch the drive/driven tracks  to the left making a right turn and right to make a left  turn. That being it does have steering.  If it does not then it will always want to go right unless both tracks are locked.  I never test run any of Ariens  track models so i do not really know how they steer .  The only trigger steering tracks I see are from troy Built .  I'm not impressed with there reliability or quality. I love Ariens,  but I question their tracks ease of steering.

Except for HONDA snowblowers they all have a "Friction Wheel" drive system.  NONE have a 'differential, like on a rear drive automobile.   Go to the Consumer Reports web site and access their section on 'Forums', then select "Lawn & Garden", then "SNOWBLOWERS".  Read the thread titled CR DOES NOT Explain Snowblowers, it explains how they all work.

NOT TRUE,

I have a 1983 Cub Cadet and it does have a friction wheel drive system with a TRUE differential just like a rear drive automobile,
here is a picture of the differential.  It can be run using the differential which will power both wheels but allow for easy turning, or you can lock the axle, but that does not allow for easy turning.

NY, true differentials have been used in friction disk drive snowblowers for 40 years.

THe Husqvarna models that have hydrostatic drive , do not have a "Friction  Wheel"

drive system,  neither does my Craftsman 529931 (built by Husqvarna ) with  hydrostatic  drive.

These models do not have an automotive  type differential.  There is no differential,  steering is accomplished by the 2 little levers below  the hand grips  that  regulates   power to either wheel ,

to accomplish either a gradual return or a zero radius Turn.

My snowblower is not a track drive, but it has a differntial.  It's 40 years old,  a John Deere 526 model.  Nice easy turning and either wheel seems to drive it when needed.  There is a lock on the left wheel that will make both wheels drive equally if wanted.  This seems to be a really good blower, and I have worked on it to replace the traction disk, but other than that, it's a winner.
