It offers 6.5 ft. lbs of gross torque with a Briggs & Stratton ready-start engine for powerful performance. The mower is a step up from the 10641 since it has a convenient electric starter compared to the manual recoil starter of the 10641. The 10642 includes Lawn-Boy's 3-in-1 system which quickly changes between the mulch, rear bag, and side discharge functions. It also has a 20" lightweight steel deck that can be adjusted to the optimum mowing height. The mower has a suggested retail price of $319 and comes with a complete 2 year warranty. The 10642 is the same model as the 10647 with the exception that it is not CARB compliant while the 10647 is.
