Yard Machines 11A-A22J700 159cc Push Mower
If you want the biggest motor with the most power in the budget class, than the Yard Machines 159cc Powermore Engine, 21 inch 11A-A22J700 Push Mower is what you need. At 159cc, the engine puts out about 7 ft. lbs. of torque and features a three-in-one design, with a side and rear discharge and mulching capability. A dual lever height adjustment lets you easily adjust the height, it comes with a bagger and in all respects, it is equal to the Lawn Boy mower for less money.
Although it’s a solid machine, the engine may not be as reliable as the tried and true Briggs and Kohler units featured on all of the other mowers in this class. But as a budget mower, there aren't any that offer this array of mowing features at this price. This mower comes with a two year warranty and works best on smaller or medium sized yards.
