Description
Briggs Stratton 25M137 Snow Engine
Briggs & Stratton 25M137 1350 Snow Series replacement engine completely addresses sub-zero starting bottlenecks and cold-weather mechanical failures facing municipal maintenance crews operating professional-grade dual-stage snow blowers. Outfitted with an adaptive dual-start network pairing a manual recoil cord with a 110V electric plug adapter, this winter machine fires up instantly during freezing sub-zero blizzards. Clearout crews comfortably conquer heavy packed ice ridges safely because a Magnetron electronic ignition block delivers reliable spark timing without requiring constant manual tuning.
Constructed inside the USA out of a heavy-duty forced air cooling chassis layout, this 24.5 kg single-cylinder engine drives an exceptional 13.5 foot-pounds of net torque cleanly. The high-performance 305 cc OHV cylinder manages a 2.5 liter per hour fuel consumption stream, storing ample gasoline volume inside an integrated 3.8-liter winterized tank enclosure. Sizing out at 450 by 410 by 420 mm overall, the 10.0 HP keyed straight PTO shaft engine block runs smoothly on 5W-30 synthetic oil lines to preserve internal component tolerances.
