Murray 20-inch Push Mower vs SENIX LSPG-M14 21-Inch Gas Mower

The SENIX LSPG-M14 is the stronger mower on paper: a bigger 144cc engine, a wider 21-inch cut, a thicker 14-gauge deck, and both mulch and side discharge. The Murray counters with a Briggs & Stratton engine, a 2-in-1 deck that is side-discharge only in practice, and a longer track record. Owners of the Murray rate it 4.1 out of 5 across more than 2,000 ratings, so it is a known quantity. Buy the SENIX for more power and mulching; buy the Murray if you want a familiar engine brand and simple side-discharge cutting.

  • Choose the Murray if you want a proven Briggs & Stratton engine and a straightforward side-discharge mower for a yard up to half an acre.
  • Choose the SENIX if you want more displacement, a wider cut, a heavier steel deck, and the option to mulch.

What reviewers say

Murray 20-inch Push Mower

  • 4.1 / 52,072 ratings

Owners rate it around 4.1 out of 5 and mostly praise the easy starting and the solid steel deck for the money. Complaints center on the side-discharge-only setup throwing clippings and on the effort of pushing it.

What people mention
  • StartingMixedMost say it fires after three primes and a pull, but some need extra pulls when cold.
  • Deck buildPraisedOwners like the 16-gauge steel deck and call it sturdier than expected.
  • DischargeCriticisedSide discharge only means clippings scatter, and there is no bag or mulch plug.
  • Pushing effortCriticisedBeing a push mower, it takes real effort on slopes and larger lawns.

Questions and answers

Which is better for mulching?
The SENIX. It has a mulch plug and blade setup for mulching. The Murray is side-discharge only and has no mulch option.
Which has the more powerful engine?
The SENIX, at 144cc versus the Murray's 125cc. The Murray's Briggs & Stratton is a well-known engine that is easy to service.
Which is easier to start?
The Murray. Its Prime 'N Pull system takes three primes and a pull with no choke. The SENIX uses a standard pull cord.
Which deck will hold up longer?
The SENIX uses thicker 14-gauge steel against the Murray's 16-gauge. Both are steel decks, and rust care matters more than the gauge difference.
Is the SENIX worth stepping up to?
Yes if you want mulching, a wider cut, or a bigger engine. The Murray is the simpler choice if you only side-discharge and value a familiar engine brand.
Which suits a half-acre yard?
Both do. The SENIX's 21 in cut covers ground slightly faster, while the Murray is rated for yards up to half an acre.
