ST14 cold-rolled steel deck built for long service life.

• 170cc Engine — More power than the standard 144cc models in the lineup. Handles thick grass, tough conditions, and larger yards without bogging down.
• Self-Propelled Drive — The mower moves itself forward, reducing fatigue on large yards and sloped terrain. You steer — it does the walking.
• 3-in-1 Mowing System — Switch between mulching (returns nutrients to your lawn), side discharge, and rear bagging for complete flexibility across all lawn conditions.
• 60L Grass Bag — Large-capacity rear bag means fewer stops to empty on medium to large yards. More mowing, less interruption.
• ST14 Cold-Rolled Steel Deck — Heavy-duty 21" deck built for long service life and a clean, even cut pass after pass.
• 6-Position Cutting Height — 1.5" to 3.9" range lets you dial in the right cut for different grass types, seasons, and lawn conditions.
• 7" Front / 8" Rear Wheels — Larger rear wheels improve maneuverability on slopes, uneven terrain, and around landscaping obstacles.
