Quick Verdict

The American Lawn Mower Company mower wins for small, flat yards where a simple, affordable reel mower is sufficient. The Ariens/Gravely 42" Mulch Kit is not a mower but a mower attachment, so it only wins for owners of compatible ZT-X zero-turn mowers who need a mulching upgrade. If you are buying a complete mower, the American Lawn Mower is the clear choice. If you already own the base mower, the Ariens kit is the necessary add-on.

Where American Lawn Mower Wins

  • Complete mower: You get a ready-to-use reel mower for $167.59. No additional equipment is needed.
  • No fuel or electricity: Manual push operation means zero emissions, near-silent mowing, and no maintenance for engines or batteries.
  • Better for small lawns: Ideal for flat, well-maintained grass under 1/4 acre. Lightweight and easy to store.
  • Higher rating: 4.0/5 from 88 reviews suggests consistent user satisfaction for its intended use.
  • Price: Lower upfront cost by nearly $40.

Where Ariens Wins

  • Faster mowing: The 42-inch cut width (when attached to a compatible ZT-X mower) covers much more ground per pass than any push reel mower.
  • Mulching performance: Designed specifically to chop clippings finely and return nutrients to the lawn. For owners of the base mower, this kit improves grass health and eliminates bagging.
  • Better for larger yards: If you have over 1/2 acre and already own a ZT-X, this kit makes mulching efficient.
  • Durability: Ariens/Gravely components are built for commercial-grade use, lasting many seasons with proper care.

Which Should You Buy

Buy the American Lawn Mower Company mower if:

  • You need a complete, low-cost mower for a small, flat lawn.
  • You prefer manual, quiet, emission-free mowing.
  • You do not already own a compatible ZT-X zero-turn mower.

Buy the Ariens/Gravely 42" Mulch Kit if:

  • You already own a ZT-X or compatible Gravely zero-turn mower.
  • You want to convert your mower from side-discharge or bagging to mulching.
  • Your yard is medium to large and you need a 42-inch cutting width.

Do not buy the Ariens kit if you do not have the compatible base mower – it will not function on its own. For most buyers, the American Lawn Mower Company product is the practical, complete solution.
