Hi Whoopsidaisy, I've used my harvest, plow and plant combine on one of my own farms that I test staggered and also on farms of neighbours who have staggered farms and had no problems with any of them.
Yes, it costs plenty of farm cash to buy your way up to it, but for me who plays on farm town regularly and runs a small business at home, it is worth every cent of it to be able to charge around farm town, then smack my fingers and get back to my work in the real world
