Maybe you have a different model than mine, but neither my KK 6 foot rake, nor my KK carryall worked with the iMatch. I had to make an adapter.
Also, Houndsman, you might want to make a distinction in the listing as to whether things that are "compatible" are that way out of the box, or do they need an adapter kit. My Frontier RFM required an adapter kit as did my Frontier rotary cutter, even though both adapter kits were available from the factory.
You may want to consider listing by what is "compliant" and what is "compatible." I believe compatible would require "adaptation." "Compliant" would mean just that -- compliant.
