Great lawn mower for a great price.

Very easy to assemble and runs great. Easy to push and maneuver (warned my wife to take over mowing soon😉). For height adjustment you have to disassemble the four wheels and put them back together (no lever). Excellent for 1/4 acre lawns. No mulching only side discharge. Happy customer 😁
