STIHL RZ 142 Gas Zero-Turn Mower – 42" Deck, 23 hp Briggs & Stratton

The STIHL RZ 142 is a 42" gas zero-turn mower for homeowners who want a compact machine with solid construction. A 23 hp V-Twin Briggs & Stratton engine, a 12-gauge welded frame and Hydro-Gear ZT-2200 transaxles form the base of the mower.

Easy starting, steady power

ReadyStart technology starts the 23 hp Briggs & Stratton PXi Series V-Twin with the turn of a key, without pulling a choke. The 3-gallon fuel tank supports longer mowing sessions between fill-ups.

Built on a welded frame

The mower sits on a 12-gauge welded frame with a commercial-grade 42" deck. Greaseable deck spindles help with long-term upkeep, and oversized rear tires keep the mower stable on uneven ground.

Simple to operate

Hydro-Gear ZT-2200 transaxles deliver up to 7 mph forward and 4 mph in reverse. Cutting height is set with a foot-operated lever, and an hour meter, deluxe seat with cup holders and a trailer hitch are standard.
