I used to regularly pick up freight from "Great states" lawnmowers (formally American mowers) they made reel type mowers & were one of the last ones that did, had a friend who worked there & he told me that the 7 blade mower was much better than the 5 blade model , his job was to sharpen the rotating cutting blades & set the cutter blade (critical) to proper clearance. if done well these mowers will cut with ease. there is a sharpening tool the can run back & forth across the cutter blade to sharpen both the cutter & real cutter blades (much like a meat slicers sharpening tool works) ,unfortunately ….most owners NEVER sharpened their mower blades.
