Our take on the Troy-Bilt 21 in. 163 cc Gas Self-Propelled Lawn Mower

The Troy-Bilt 21-inch self-propelled mower is a gas walk-behind built for lawns up to about half an acre. A 163 cc engine drives a 21-inch rotary deck, and the self-propel drive takes the push out of slopes and long strips. Its best new price is $422.29 at Opentip.com as of November 5, 2026, with three stores listing it new. That is a mid-pack price for a 163 cc self-propelled mower, so compare it against the store's own recent pricing before you commit.

Questions and answers

Is the Troy-Bilt 21-inch self-propelled mower worth it?
It is a reasonable buy if you want a basic self-propelled gas mower for up to half an acre and don't need electric start. At $422.29 at Opentip.com as of November 5, 2026, it sits in the normal range for this class. Check the return policy, since owner ratings are only average.
How does it compare with a cordless electric mower?
Gas gives you unlimited runtime and more torque in tall grass, but you deal with fuel, oil changes and pull starting. A cordless electric mower is quieter and starts instantly, though batteries add cost and limit run time on larger lawns.
What size lawn can it handle?
Troy-Bilt rates the mower for about 0.5 acre. The 21-inch deck and 163 cc engine suit weekly cuts on a typical suburban lot. Larger or very overgrown lawns will take longer and may warrant a wider deck.
Does it have electric start?
This model is pull-start only. There is no battery or key start, so you pull the cord each time. If easy starting matters, look at Troy-Bilt models with electric start.
What comes in the box?
You get the mower, a grass bag and the usual discharge and mulching setup for the deck. Gas and oil are not included, so plan to add fresh fuel and check the oil before the first use.
When is the price lowest?
Gas mowers usually discount in late summer and early fall as stores clear inventory. The current best is $422.29 at Opentip.com as of November 5, 2026; compare all three listings before buying.
