Had a nice conversation with a couple of the TSC Merrimack guys while waiting for my tiller to be loaded. It's clear that they are as clueless about the ongoing transition from KK to FF implements as anyone anywhere. Let's be honest here: TSC is not exactly being vocal & high profile about this change in suppliers and they are going out of their way to copy the KK implements almost to the last nut and bolt.
That is true regarding the staff knowing anything about 3 pt hitch attachments. Actually, I was asked to speak to the person regarding the rotary cutter as the person there didn't want to be in the position to relate the information to me. That is fine and it was good for me to speak to them. I also agree on the duplication of the FF to look like the KK machine. The only problem I have with the situation is the literature rack right at the service desk has all KK literature and it is what they handed me when I placed the order for the darn thing.
The company line is that KK simply could not keep up with ever increasing demand from more and more TSC stores opening every month. Hence the decision to launch a company-captive brand with two new suppliers. At first (and for a long while) you could buy FF stuff sitting right beside near identical KK stuff. Now, almost everything is FF except the tillers (which are supposedly to remain KK for good) and certain other special ordered stuff.
I looked at your tiller when I picked up the hog. They had moved it off away from the other stuff and had it marked sold. Looks good and I am sure I will be buying the small model of that in the spring. Hope it works out for you.
While some have pointed out dropped features, different/cheaper component suppliers and lighter overall implement weights... most of the FF stuff still looks like a pretty good bargain to me. Welds and paint are noticeably better on FF stuff... but sloppy welds and running paint was kinda like a KK tradition.

I own two FF implements and am quite pleased with both. I probably would have bought a FF bush-hog if they came with slip clutches and dual rear wheels.
