There were not that many attachments. In fact, it seems Bolens only offered three.
Well, isn't that enough? lol... I know it didn't have as many attachments for it as other Bolens tractors, but with those gigantic mower, snowblower, and plow blade attachments, you could still do a lot with them. Also, as I recall, a lot of attachments for many other Bolens tractors were not actually manufactured by Bolens either. For example, the sickle-bar mowers, flail mowers, and de-thatchers designed for use with the tube frame or large frame tractors were all made by other companies, like Haban. Is it possible that if the GK were more of a success and was made for longer than 2 years, these manufacturers may have started developing other attachments for this machine as well? A good one that comes to mind for the GK's would be either the flail mower or a brush-hog type mower to quickly rough-cut down large fields of brush where a finish mower is not necessarily needed.
Also, not that it is an attachment really, but it was an option at least, but they did make the nice solid cab for the driver's compartment as well. I'd imagine that was almost a necessity for snowblowing with it in the winter. For mowing in the summer with it... meh, not so much, probably.
IMO, I think Bolens' mistake might have been to make the GK a gear drive, 2-wheel drive tractor. I think had they made it hydrostatic and all wheel drive, they would have had more commercial success with it.
I do agree 100% here as well. I'm sure the gear drive was cheaper and possibly even more robust to implement in this machine, but it also makes it a lot more difficult to operate, especially for long periods of time as you would expect for commercial use. I'm not sure why they didn't made this hydrostatic drive either myself. (Unless that was still quite rare for the late 1960's?) I'm hoping that if it had continued to see production into the 1970's that they would have made a hydrostatic version of this tractor. I agree 4 wheel drive would have also been nice, but it seems like it would have been a lot more difficult to implement, especially back then. I think newer 4x4 commercial mowers (for instance, by Toro) are only implemented my having hydraulically operated drive spindles at each wheel, which is very expensive to engineer and produce. I think it would have been too cost-prohibitive for Bolens to try to engineer a 4 wheel drive system on a frame steer tractor like this. Even most of their large frame tractors were not 4 wheel drive either, as far as I am aware. They probably didn't start manufacturing 4x4 tractors until the mid to late 1970's at least.
