Snapper 675 Series 190cc 21" Briggs & Stratton 3-In-1 Rear Bag Key Start Rear Wheel Drive Lawn Mower —
I've used mower 3 times since I bought it.
The first time I used the Pull Start (right out-of-box & added gas/oil and adjusted the handle and wheels) - the grass was very high and since the mover was preset to mulch so I used that feature - I was concerned that the grass might be too thick & high, but the snapper powered though it just fine - afterwards it looked even without a trail of grass clippings.
The second time was after I charged the battery - the key start worked fine. I mowed the yard in record time.
The third time was after several days of rain - the grass was still semi-wet in spots and high in other spots. No-problem for this snapper.
Overall, my yard has never looked so good. This has been the best mover I have used. I wholeheartly recommend it.
BTW: My earler mowers were Cub-Cadet, Lawnboy, Murray & Toro - each lasted several seasons but ultimately all failed/died prematurely [different reasons]
