## At a glance

- 21-inch cutting width with six height positions spanning 1.25 to 3.75 inches.
- Listing describes mulching, side discharge, and rear bagging, with a 1.7-bushel bagger.
- Manufacturer claims the 144cc 4-stroke OHV engine delivers 3.4 HP and 5.8 ft-lb of torque.
- The listing suggests suitability for yards up to 1/3 acre. This is a manufacturer claim, not a verified coverage guarantee.

## Pros

- Three listed clipping options let buyers choose between mulching, side discharge, and bagging.
- Six cutting-height positions offer adjustment across a stated 1.25-to-3.75-inch range.
- The supplied listing identifies a 1.7-bushel bagger and a steel deck.

## Cons

- This is a push mower, so moving it across the yard requires the user to provide the pushing effort.

## Before you buy

- 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.

## A good fit for

- Buyers seeking a gas-powered push mower with a 21-inch cutting width.
- Homeowners who want listed bagging, mulching, and side-discharge options.
- Buyers who value six selectable cutting heights and a stated bagger.

## Less suited to

- Shoppers who prefer a self-propelled mower or do not want to push the machine.
- Buyers who need independently verified yard coverage or performance figures.

## Customer feedback

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.
