Rated 3.8 out of 5 by 97 reviewers.
Rated 3 out of 5 by Commercial User Have bought 4 of these mowers. A good cut, fast speed on the ground, not to heavy. Problem is the bearings in the drive assembly don't last long. Pity as otherwise a great mower. Getting parts in the UK a problem. Approved dealers not much help. May 29, 2014
Rated 4 out of 5 by Very nice mower. I like the Ariens mower for several reasons. 1) the bagging is unbeatable, even in the rain, it will completely pack the catcher full - no clogs. 2) Starts every time the first time. 3) The Kohler motor, even though it is small in cubic inches, it has plenty of horsepower to handle tall grass and blow through it.

Rated 1 out of 5 by worst purchase ever never ran correctly from purchase problems never fixed had to return to store for multipul fixes and by the time they fixed it the mowing season was over. April 6, 2014
Rated 1 out of 5 by My Ariens mower was junk, so I brought it back to the store After using my mower once a week for 3-4 months, it stopped working reliably. It would work well for 5-10 minutes, then not work again until it had cooled down completely. Having to mow your lawn in 5 or 6 shifts is ridiculous. Tried different gas, cleaning all the filters, new spark plug, nothing would help. Even when it did work, it had a horrible design. The self-propulsion is belt-driven, and the belt is exposed to all the grass clippings under the mower deck. Sounds like a joke that an engineering professor would tell his students in class. Anyway, I brought it back for store credit and I've been happy with the replacement (another brand) June 12, 2012
Rated 4 out of 5 by LM21 Hit a rock in lawn early last season, bent blade in half weak steel used in blade construction. Try to go back to Home Depot for new blade but they don't carry Arien replacement parts. Ariens dealer 50 km away. Found aftermarket blade at Canadian Tire now mower shake and vibrates. Motor shaft is not bent and I get blisters everytime I use it. Now used Sunday morning cut half the lawn in morning waited until after dinner went back to finish and lawn mower will not start at all. I think I would rather use the weed eater than the lawnmower to cut my grass. Overall strong engine wide cut width pleased with that but not much more. June 12, 2012
