Our take on the 21" 140cc Gas Self-Propelled Lawn Mower

A 21-inch gas walk-behind mower with a 140cc Briggs & Stratton E550 engine and a self-propelled drive that takes the push out of mowing. The cold-rolled steel deck carries a 20-inch blade, and a 60-liter catcher means fewer stops to empty clippings. Six cutting heights from 1.5 to 3.9 inches cover most lawn conditions, and 7-inch front with 10-inch rear wheels roll over uneven ground. It suits homeowners with a mid-size yard who want a conventional gas mower with a large bag; it is heavier and louder than a battery mower and needs gas, oil and seasonal upkeep.

About the 21" 140cc Gas Self-Propelled Lawn Mower

Questions and answers

Is the self-propelled drive front-wheel or rear-wheel?
The listing does not specify the drive type. It only states that the mower is self-propelled, so check the drive layout before buying if traction on slopes matters to you.
Does it mulch or side discharge?
The listed features cover bagging only, with a 60-liter catcher. Mulching and side discharge are not mentioned, so assume it is a bagging mower unless the full manual says otherwise.
What maintenance does the Briggs & Stratton E550 need?
Like most small gas engines, it needs fresh fuel, oil level checks, an air filter and spark plug service, and a blade sharpening each season. Drain fuel before winter storage.
How large a lawn will the 60-liter bag handle?
The 60-liter catcher is large for a walk-behind mower, so it should cover a good stretch of lawn before emptying. In tall or wet grass you will still stop more often.
Is a 140cc engine enough for thick grass?
140cc is modest for a 21-inch deck. It handles regular lawns fine, but tall, wet or thick grass will slow it and may need a slower pace or a higher cut first.
What cutting height range does it offer?
Six positions from 1.5 to 3.9 inches. That covers a short trim up to a taller cut for dry or heat-stressed grass.
Where is the 21" 140cc Gas Self-Propelled Lawn Mower cheapest?
