- Six cutting-height positions offer adjustment across a stated 1.25-to-3.75-inch range.

What to know before buying
Listing details to confirm
The 1/3-acre yard suitability, engine output, and claimed low-vibration and easy-maintenance benefits are manufacturer statements, not independently verified performance results. The title specifies a steel deck, while the material detail says Alloy Steel and the feature copy describes low-carbon, high-strength steel. The product dimensions list 8-inch wheels, but feature copy specifies 8-inch front and 11-inch rear wheels. Confirm these listing details and the configuration supplied before purchase.

Aggregate ratings lean positive, with the recorded ratings limited to four- and five-star categories. This is a small sample and provides no detail about mowing performance, durability, or the listed cutting modes, so buyers should not treat it as a substitute for confirming the mower's configuration and stated specifications.
Frequently asked questions
What mowing modes does the listing specify?
It describes mulching, side discharge, and rear bagging. The listed bagger capacity is 1.7 bushels.
How many cutting-height settings are listed?
The listing specifies six positions, with a minimum height of 1.25 inches and a maximum of 3.75 inches.
Is this mower self-propelled?
No. The product is described as a push mower, so the operator supplies the forward movement.
What should I verify about the wheels and deck?
Listing details conflict: the dimensions entry gives 8-inch wheels, while feature copy says 8-inch front and 11-inch rear wheels. Deck material wording also varies between steel, Alloy Steel, and low-carbon, high-strength steel.
