It wouldn't be for me, but it looks like you have spent a lot of time designing it. Here's what would deter me
1. As a farmer with no help around, how much time and effort is required to swap and un swap this ? I have one tractor and at seeding time I usually spray a few fields ahead then seed. I would not want to be un hooking the drill and swapping over. The stage the weeds are at are not always even field to field so I like to spray according to what the field needs the day before I get to it.
2. I can't see it being useful for pre harvest burn down as the tracks or tires would trample too much crop.
Maybe there is a niche market for you , I hope you succeed in getting it on the market.
Our marketing plan with it is it can be a compliment your farming operation by being a second or back up sprayer when needed and not have the additional capital expense of running another power unit since you would already have the tractor. For taking the sprayer on and off, this can be done in about 10 minutes once you have everything installed on the tractor and easy to unhook ie..wiring, plumbing etc...
Spring time is always busy for everyone and to have another unit available when the weather is not cooperating to get out there and get the spraying done we will is where this unit will have its advantages.
We have it direct mounted on the CASE because the 3 PT option is a lot of money to have on the tractor so we wanted to be able to mount it to tractors that do not have 3Pt hitches.
Thanks for your thoughts, we also hope we can get these into the right markets.
