Altair Any tire on ice never produces great traction, so the problem with an open differential comes down to lack of traction from the tires.
The standard solution to this is of course is chains, or ice screws (studs).
However, if the differential is viscous-damped the wheel that is not on ice will still have some torque and will be able to make the machine move, at a slower speed until the other wheel regains traction.

I have not tried adding extra weight to the bucket. From the reports of others a 10 lbs kit is not usually enough and 20 lbs is more likely to keep the bucket down.

I like a heavier bucket feel that helps keep the bucket down under some conditions and my machine seems to have enough weight for me. An alternative to adding extra weight is to lift the handles a little under the conditions causing the front end to lift a little. The problem with extra weight on the bucket is lifting the bucket can get tiring when blowing for a long time, depending on age and related muscle function.

Since the Ariens 10 lbs weight bar kit is expensive in Canada and you may need 2 kits for a noticeable improvement, I would try adding some cheap weight lifting circular weights of 5 lbs or 10 lbs to each side of the top of the bucket where the Ariens weight bar kit holes are located. If that works for you then you can get a custom kit made for less.

Just my opinion.

Town An open differential on a snowblower is totally useless as @Dauntae suggests when real differences in snow conditions exist as in the real world. My 1974 Canadiana 8/26 had an open differential that was only open for a short time before I locked it out with the control feature because it had no drive in most real world situations. Chains helped with the turf tires but not adequate and a very lumpy ride that I hated for 30 years. It was better to have a locked drive and struggle with turning. My 2004 Craftsman with triggers was also useless fumbling to use the triggers with mitts is no fun at all but modern tires helped a lot with traction so no chains. I found it better to just muscle the machine around.

Whatever the technical description of the Ariens AutoTurn differential it is actually a true operational differential. Both wheels drive equally at the same time regardless of the snow/ice conditions and load on the bucket. The upgraded snow tires help a lot too. When you want to turn the machine turns very easily right or left or a complete 360 degrees with no effort at all. There may be some clicking during a turn but who cares compared to a fully locked differential that is almost impossible to turn at all. Differentials used in autos cannot be compared to snowblowers since the operating conditions are completely different.

The Ariens with AutoTurn and their plastic skid shoes had no problems at all with AutoTurn but those with steel skid shoes did exhibit a squirrely straight line drive under some conditions (I tried them briefly to confirm). The obvious solution was for Ariens to make the plastic skid shoes stock and the steel ones optional. Instead Ariens chose the more complex solution of re-engineering the weight balance like the Pro machines that had no problems with a squirrely drive or riding up on snow. The weight kit has been available for a long time before 2017 models for those interested in a heavier feel to the bucket. Ariens AutoTurn customers are very happy with the Ariens re-balancing and have commented on this forum in numbers. So you can fit steel skid shoes or plastic skid shoes to your 2017 and up model and be delighted with the best differential system on the market. Much better than triggers which I have used too, much better than manually locking differentials that demand constant attention in most conditions where turning and real world snow conditions are prevalent.

Dauntae The 924 series had more of a true differential but the reason they put a lock is when one tire is in snow and the other is on ice the one tire just spins and you go nowhere until you reach down and lock it. The autoturn was there attempt at keeping the diff but more of a limited slip variant Or semi locked so you won’t slip one tire but still able to turn it without having to reach down to lock or unlock the diff.

Altair I second foggysail above regarding a differential. Yes, nothing compares to a true differential, and certainly not what ariens dares to call an "automatic differential", which is actually a bi-directional Sprag clutch. Autoturn is also just another kind of clutch. A differential is always smooth with no sudden engagement or disengagement, torque is transmitted continuously, in fact you don't feel it working. Must be the reason all cars & trucks in the world use them...


I wish there was an aftermarket company that offered a replacement "True Differential" that we could retrofit to our machines.


As foggysail wrote, it should be sealed. Additionally, I would want it to be filled with highly viscous grease, so that it has some limited-slip characteristic.

foggysail Yes, Ariens moved the wheels forward to help the auto turn. Doing so made the machine too light in the front causing it to climb forcing Ariens to find another fix and indeed they did. They sell a weight kit that bolts onto the front of the thing.......new machines even have pre-drilled holes to accommodate the added weight.

I bought a 25# SS bar on Ebay which a I mounted onto the front of my 28 Pro. Seems to make things better. Nothing in my humble opinion can compare to true differential, one designed with seals to keep the melted snow out of it along with zerk fittings for lubrication

Town No vibration through the handlebars on my engine at 3,925 rpm or any lower speed. No vibration when the 6 blade impeller is engaged driving at 1,447 rpm. I like the Ariens and the LCT engine. Tecumseh 8 hp and 11 hp are not as smooth. My only experience with Honda engines is a 4 hp OHC, a GC something, a long time ago. It was a terrible engine with no power compared to the 3.5 hp side valve B&S that it replaced. Never looked at Honda since. Someone posted a review of GC versus GX here a short time ago and the differences are negligible.

1132le my 414cc is quiter then both my 10 hp and 8 hp tech flatties also the oh358cc 13 hp
sounds like splitting hairs to me
