Rated 1 out of 5 by from Not reliable Purchased 2years ago. From the beginning the mower would often stop for no apparent reason. Took to shop several times and had the carb. cleaned.Mower would then run for maybe two mowings then the same problem occurred.Was told by shop there was no repair kit available for carb. Now mowing with a ten year old mower with a B&S engine. Tired of taking mower to repair shop.

Rated 1 out of 5 by from very poor design easy start, runs great - UNTIL - I push mow around and under trees and bushes, which cause the gas and oil cap to come loose, sometimes causing fluids to spew all over the engine and deck. this last time the entire oil dipstick was pulled from the engine. Engineers, you are welcome to my place for hands on testing, research & development...

Rated 1 out of 5 by from Bought recently mowed great once. Second time for 10 minutes, sputtered and choked out. Pathetic performance and now it has to go to the shop almost new. Not worth the money.

Rated 1 out of 5 by from bad design Worked well for two years. Hit a small shrub stump 1" stopped the engine. Started back up, up but the mounting bolt cracked off, with a hole in the crank case shooting oil out. Too light weight not durable enough!

Rated 1 out of 5 by from simple operation wont start. One thing is that there is no fuel filter. This should be a warranty repair if a no start condition means that the carburator needs cleaning inside.No matter how carefull you are with keeping it clean-junk gets in the system.
