3-in-1 Mowing Function

3-in-1 Mowing Function

Maximum versatility tailored to your lawn's needs. Easily switch between eco-friendly mulching, clean side discharging, or collecting clippings with the massive 16-gallon (60 L) heavy-duty grass bag.

No, it does not. The SENIX LSSG-M10 is powered by a premium 170cc 4-cycle RATO engine, which features separate compartments for gas and oil. You can pour unleaded gasoline directly into the fuel tank without the messy hassle of mixing. Note: Always ensure the oil reservoir is filled to the correct level before your first start.

A self-propelled mower does the heavy lifting for you. The M10 engages a rear-wheel-drive system that automatically propels the machine forward. Instead of manually pushing a 61.7 lb machine, you simply guide it. This makes mowing large yards, thick grass, and steep slopes effortless and strain-free.

It offers three distinct ways to handle grass clippings for ultimate lawn health:
* Mulching: Chops grass into fine nutrients that feed your lawn.
* Bagging: Collects clippings cleanly in the massive 16-gallon rear grass bag.
* Side Discharge: Discharges clippings out the side for fast, high-volume mowing.

Absolutely Yes. The SENIX LSSG-M10 is specifically engineered with an oversized wheel configuration—8-inch front wheels and 11-inch high rear wheels. This staggered design provides superior traction, increased stability, and smoother maneuverability over ruts, bumps, and slopes up to 15 degrees.

The SENIX LSSG-M10 features a highly precise 6-position dual-lever height adjustment system. By simply moving the adjustment levers located at the wheels, you can instantly customize your cutting height anywhere from 1.25'' to 3.75'' to match your specific grass type and season.

The SENIX LSSG-M10 lawn mower is backed by a 3-Year Limited Warranty for residential use, giving you long-term peace of mind and guaranteed reliable performance season after season.
