KK sells a great tiller that'll hold its own against any brand, a very good for the buck "heavy duty" (for KK) disc (not to be confused with their light duty model) , the landscape rake is basically the same or similar to most others, and some assorted "ok" stuff. Rough mowers hold up to lighter duty use. Had a finish mower, wouldn't rush right out and buy another. Rear blades are ok for pushing sawdust, snow and loose dirt. Don't try to do much serious digging with one. I ended up taking a cutting torch to one I wadded up while scraping snow 3 years ago. (with a 40 hp tractor) Box blades are "average" for economy level. Prices on KK equipment seem to be catching up with everything in it's same quality range. Not the bargain it once was. Most KK equipment uses "generic" components available most anywhere. (i.e. pto shafts, slip clutches, disc bearings and wear parts, box blade ripper teeth, ect) That's a plus.
There's better quality equipment available, but there's worse. Average quality at an average price but easy to find retailers.
