Tackling tough mowing tasks doesn’t have to mean sacrificing comfort or control. With the PowerSmart self-propelled gas lawn mower, you get the muscle you need and the ease you want.

Powered by a Reliable B&S Engine: The 140cc Briggs & Stratton engine delivers smooth starts, steady performance, and long-term reliability. It's built for power and perfect for more demanding yard jobs.

21-Inch Cutting Width for High Efficiency: A sturdy steel deck provides a wide 21-inch cutting path, helping reduce mowing time—ideal for medium to large-sized lawns.

3-in-1 Function: Bagging, Mulching & Rear Discharge: Easily switch between clipping collection, mulching, or rear discharge. A 1.4-bushel grass bag is included for clean, efficient yard work.

6-Position Height Adjustment: Use the single lever height control to adjust cutting height from 1.5 inches to 3.9 inches, giving you full control over your lawn’s appearance.

Self-Propelled with Large Rear Wheels: The rear-wheel drive system and 10-inch rear wheels provide enhanced traction and maneuverability, especially on slopes or uneven terrain.

PowerSmart gives you a lawn mower built to handle big tasks with less effort. It's power, precision, and performance—all in one machine.

How does the PowerSmart self-propelled mower handle slopes and uneven terrain?

The rear-wheel drive system is the key advantage here. Rear-wheel drive maintains traction at the back of the mower where the weight sits, which prevents slipping on inclines better than front-wheel drive models. Combined with 10-inch rear wheels that roll over bumps and dips without losing momentum, it handles moderately sloped residential yards significantly more confidently than a standard push mower.

What is the practical difference between the three cutting modes?

Each serves a different priority. Bagging collects clippings for a clean finish and is best when grass is long or you want a manicured look. Mulching chops clippings finely and returns nutrients to the soil, reducing the need for fertilizer over time. Rear discharge spreads clippings behind the mower and works best for fast mowing when clipping disposal isn't a concern. Switching between modes requires no tools.

Is a 140cc Briggs & Stratton engine enough power for thick or overgrown grass?

For most residential applications yes. The 140cc B&S engine is a well-proven platform known for reliable starts and consistent output across varying grass conditions. Where it shows limitations is in very tall or wet grass that bogs down smaller engines. For heavily neglected lawns, making a higher initial cut before dropping to your preferred height keeps the PowerSmart mower running smoothly without straining the engine.
