The YARDMAX 21" 3-in-1 push mower is perfect for the homeowner that wants a mower with all the features and is easy to use, but doesn't mind pushing. The 170cc OHV Yardmax engine delivers maximum performance in this class of mower. The YG1650 features a high-rear-wheel design, and all wheels are equipped with durable 1.5" wide treads and with double ball bearings, all of which makes for easier pushing and for even cuts. Cut your lawn to your specifications by using a single convenient lever to select one of seven cutting heights, from 1.25" to 3.75". The MaxFlow volute deck is designed to keep grass clippings airborne longer for superior mulching, or for flowing into the rear bag when needed. The entire mower can be compactly folded for stowing in tight garage spaces. Only limited assembly required.
