I have been looking at this unit, too. It is a bit on the pricey side but is intriguing nevertheless. I was thinking of it for use with my 4 bush-hog on the front. I do a fair amount of my bush-hogging going in reverse along the edge of my fields and it is a pain in the neck (literally) and thought it would be nice to do that going forward. I also think it would solve my snow blowing in reverse issue as well.
I purchased a Radtech B54 3-point snowblower in part because it was half the money but it also seemed to be a better-built blower than the front mount Massey Ferguson unit, even though Radtech makes that as well. I had once owned the Kubota version of that front mount blower and I was not impressed with its quality and durability. I got quite good at repairing it. I certainly could not see the $3,750.00 price tag even though part of that cost is the mounting kit that can also accommodate a plow and broom. Even though the MK-Martin kit is expensive, I could blow snow going forward and have a better-built blower out front. Also, this front mount kit would allow me a bit more versatility using 3-point attachments on the front and I would not be tied to buying only MF front mount implements. Something to think about, I guess.
