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

While I was snowblowing today, I suddenly realized that only one wheel is getting power.  The other spins freely.  Apparently something is broken.  Might it be something simple like a sheer pin, or am I looking at a more expensive repair?

Thanks,

Jeff

Interesting.  I've had this snowblower for 14 years and never knew that there was a pin in the axle that could be used to control whether the wheel gets power or not.  Thanks.  I'll check it out.

What's more interesting is that you've been using it for 14 years and you just suddenly realized it! :)

Its probably more a comment on the weather. It finally got bad enough so that having extra traction on the straightaways became noticable. For light stuff ( a.k.a. Fluffy) I use oe wheel free. For heavy stuff where we need traction I lock the wheels. I'm saving my pennies for a machine with a differential  but have been wondering if the trigger release would be "good enough".

Actually, I know that both wheels were getting power until the incident I'm asking about, and it has always been that way until now.  I still haven't looked at the snowblower to determine exactly what might have happened.

Most of the old Ariens had both wheels locked to the axle with a Woodruff Key - a half-moon shaped piece of metal that locked the wheel hub to the axle but allowed it to slide out if necessary. they fit into semi-circular notches in the axle. It could have fallen out or become dislodged.

You can buy a replacement at the dealer for about $1.50 or buy an unplated one at Home Depot for about $0.50.

If yours is unlockable, you'll likely have a knob on the wheel that looks like the one in this picture near the tire stem.

As it turns out, my wheels are not unlockable, and are held onto the axle by a simple nut and bolt.  One of the bolts had rusted off.  I replaced it.  Checked the other side and it is in good shape.  I bought an extra nut and bolt "just in case".

Thanks for all the ideas.
