BigDog Alpha MP Residential Zero Turn Mower with 42″ Deck

Ready to work

Who knew a mower could look so good? Get all the power and speed you will ever need with the Alpha MP. The Alpha MP provides maximum style and performance standards with a Briggs & Stratton PXi engine, a premium seat, and a rugged engine guard.

The Alpha MP zero-turn residential mower has all the speed and power you'll ever need. The Alpha MP's steel constructed frame, 11 ga. welded fabricated steel deck adds durability and extends the life of the mower. The precision steering maneuvers and trims easily around obstacles. Other brands have overly sensitive steering arms, causing sudden and jerky movements. The foot-operated deck lift adjusts the cutting height from 1.5n to 4.5in easier than hand-operated levers. The Alpha MP's seat has a higher back than the BigDog Alpha and suspension springs for greater comfort while you are mowing. The 20" BigBite Tires and larger 13in front caster tires enhance traction and provide a smoother ride. 

Ideal for yards up to 3 acres, the 2020 BigDog Mower Alpha comes with a 7 year or 300-hour industry-leading residential warranty.
