Our take on the DeWalt 12AVP2R3739 21 in. 163cc Gas Self-Propelled Lawn Mower

The DeWalt 21 in. 163cc Gas Self-Propelled Lawn Mower is a walk-behind mower with a 21-inch rotary deck and a 163cc gas engine, built for lawns up to about half an acre. It is self-propelled, so the mower pulls itself while you steer, which helps on slopes and long strips. DeWalt positions it as a contractor-grade machine, and it competes with other 21-inch self-propelled gas mowers on deck size and engine displacement rather than on extras. Owner feedback is mixed: the cut and the engine draw praise, while starting, assembly and long-term durability come in for criticism.

Questions and answers

Is this mower good for a half-acre lawn?
Yes. It is rated for up to 0.5 acre, and the 21-inch deck and self-propelled drive suit lawns of that size. Larger lawns will take considerably longer.
Does it mulch and bag?
It uses a rotary blade system, and the deck is set up for standard discharge, mulching and bagging. Check the specific configuration before buying if bagging is essential.
How does it compare with other 21-inch self-propelled mowers?
It matches rivals on deck size and engine displacement, and the DeWalt name brings a wide parts network. Its weaker point against rivals is owner-reported reliability and starting.
What maintenance does the gas engine need?
Like any gas mower, it needs fresh fuel, oil changes, spark plug checks and off-season storage prep. Skipping these is a common cause of the hard starting owners report.
Is it hard to assemble?
Several buyers say assembly and setup instructions are unclear. Having a second person help with the handle and deck adjustments makes it easier.
