well a call into them and they won't be releasing until May or so. Soooooo wondering what to do at this point. they say it is only at 4.5 mph and are trying to get a higher speed on it. at 4.5 I would say it is not worth it. but at say 6-7mph and doing 1-1.5 acres and hour would definitely be worth it. said pulls around 9holes per sqft. and a price of 4250.00 and 350 for the sulky. We will see. I would love to have one of these if it is more productive than what I have.
