Lee Valley 18 inch push mower with the grass catcher.
The following description is taken from the Lee Valley web site.
The 18" mower is a great all-purpose mower that cuts virtually any type of grass. Mid-size and mid-weight, it has greater cutting height than the 14" mower but less than the 20" mower (ranging from 1/2" to 2-1/4"). The five-blade reel has 18" wide blades (actual cutting width 17"). Weighing 24 lb, it has 10" diameter wheels. The grass catcher weighs only 3 lb and fits all three Lee Valley reel mowers. Constructed of fabric with a plastic base, it holds a full bushel of clippings.
