SURTEC NTLM51-2L(NP170)

SURTEC NTLM51-2L(NP170) is a high-capacity walk-behind mower built for the larger end of the residential yard and the lighter end of the commercial lawn-care workload. Powered by a 5.5HP Zongshen NP170 engine running at 3,600 rpm with 171cc of displacement, the unit delivers the steady torque and dependable cold-start behaviour that operators need when they are working through denser stands of grass in a single pass, rather than splitting a large lawn across many short runs. The NP170 sits in the established lawnmower engine class that has long powered mid-to-large walk-behinds in this displacement bracket, so service parts and routine maintenance procedures are familiar to dealers, rental fleets and end-users alike.

The cutting platform is sized to match that workload: a 20-inch (510 mm) steel deck that lets the operator cover more ground per pass than the typical 16–18" residential mower, paired with a six-position central height-adjustment lever that ranges from 30 mm to 80 mm. That range covers everything from a tidy weekly cut on cool-season turf to a longer summer setting for warm-season grasses or for clearing a slightly overgrown patch after a break in the maintenance cycle. High-wheel geometry — 8 inches at the front and 11 inches at the rear, rolling on ball bearings — keeps the mower tracking smoothly over uneven ground, root zones and shallow ruts, which is exactly the kind of terrain encountered on larger homeowner lots, rural plots, and small estate grounds.

A 70-litre hybrid catcher with a fill-level indicator extends uninterrupted working time by reducing how often the operator has to stop and empty the bag, while a 4-in-1 cutting system gives the flexibility to mulch clippings back into the lawn for nutrient recycling, bag them for a clean finish, side-discharge when the grass is too tall to bag cleanly, or rear-discharge into rows for rough areas. A soft-grip ergonomic handle with three-stage height adjustment adapts the working posture to operators of different statures, and a heavy-duty steel deck protects the chassis from the stone-chips and root-strike that come with large, less manicured lawns. Together these features make the NTLM51-2L(NP170) one of the most versatile large push lawn mowers in the SURTEC residential-and-light-commercial line.

For B2B partners, the platform reads as a natural upsell from smaller 16" and 18" hand-push mowers in the same family, while still being light enough at 29 kg for a single operator to load, transport and store without dedicated lifting gear. The combination of a high-capacity catcher, a wide cut, a 4-in-1 deck and a proven lawnmower engine class makes NTLM51-2L(NP170) a strong fit for outdoor power equipment distributors, lawn mower dealers, and grass mower company procurement programmes that want a single SKU to cover both large homeowner yards and entry-level light commercial lawn services.
