Detailed Description (from Product Description)
This lightweight residential steel deck mower is designed for tight spaces and straightforward yard care. The 144cc engine is a typical size for small-to-medium lawn mowers, offering an ideal balance of power and fuel efficiency for homeowners. The reinforced steel cutting deck resists warping and supports a sharp 21-inch blade to make fewer passes and get the lawn done quicker. The 1.4 bushel grass catcher keeps clippings contained for a tidy finish, and mulching capability lets you return fine clippings to the lawn as a natural fertilizer if preferred.
Assembly is minimal — the unit arrives fully assembled and only requires unfolding the handle. The foldable handle and compact footprint make it easy to store in a small garage or shed. The large rear wheels offer greater traction and smoother pushing on bumpy terrain, and the six height settings let you adapt the cut depending on grass type and season.
