Craftsman M220 21" Self-Propelled Mower vs Craftsman M300B 21-inch Self-Propelled Mower

These are close siblings: same 140cc engine, same 21-inch 3-in-1 deck, same six-position dual-lever height range. The real split is the drive. The M300B sends power to the rear wheels, which grips better on slopes and wet grass and is easier to steer through turns; the M220 drives the front wheels and is the simpler, lighter-feeling machine. Buy the M300B if your lawn has any grade to it. Buy the M220 if your yard is flat and you want the least fuss.

  • Choose the M220 if your lawn is flat and you want a straightforward front-wheel-drive mower with the same deck and engine as its sibling.
  • Choose the M300B if you mow slopes, uneven ground or damp grass and want rear-wheel traction pulling the deck.

What reviewers say

Craftsman M220 21" Self-Propelled Mower

Owner feedback on the M220 is mixed. People like the value, the wide cut and the easy height adjustment, but the fixed single speed and the pull start draw complaints.

What people mention
  • Drive speedCriticisedOwners say the single-speed drive sets one pace that feels too fast for trimming and too slow for open lawn.
  • StartingMixedThe pull start works once running, but several owners find cold starts take repeated pulls.
  • Cut qualityPraisedReviewers report an even cut and good mulching on maintained lawns.
  • Cutting powerCriticisedTall or wet grass bogs the 140cc engine, so owners take slower passes or a second cut.

Craftsman M300B 21-inch Self-Propelled Mower

Owners of the M300B line generally find it a dependable, easy-to-push mower for mid-size lawns, with rear-wheel drive helping on slopes. Common complaints center on the fixed single speed, the pull start and the fiddly two-lever height adjustment.

What people mention
  • Drive speedMixedOwners say the single-speed drive works but leaves no way to slow down or speed up to match their pace.
  • TractionPraisedRear-wheel drive is reported to hold grip on slopes and thick grass where front-drive mowers slip.
  • StartingMixedThe engine is called dependable once running, but the pull start takes several pulls when cold.
  • Cut heightCriticisedThe dual-lever adjustment is described as slower and less convenient than a single-lever system.

Questions and answers

Which is better on a sloped yard?
The M300B. Rear-wheel drive keeps the tires loaded as the bag fills and holds grip on grades where a front-drive mower starts to slip.
Is the M300B worth stepping up to over the M220?
Yes if you have hills, uneven ground or damp grass. On a flat lawn the M220 does the same cutting job with easier steering.
Do they cut the same?
Yes. Both use a 21-inch 3-in-1 deck with a 140cc engine and the same six-position, 1.25 to 3.75 inch height range, so cut quality and finish are effectively identical.
Which is easier to maneuver?
The M220. Front-wheel drive lets the rear end swing freely, which helps around trees, beds and tight corners.
Which lasts longer?
Neither has a clear durability edge; the engine and deck are shared. Rear-wheel drive wears its drive tires harder, while front-drive systems see more slip. Maintenance matters more than the model.
Can both mulch and bag?
Yes. Both are 3-in-1 decks: bag, mulch or side discharge, with a rear bag included.
