I am not a big fan of spray to be honest because they just cost so much these days. I am planting 10 acres of sunflowers next year, and just sitting here thinking outside the box. I have a 4 row cultivator that works great till the sunflowers get to tall but is there anyway to cultivate them after? I thought about planting 38" rows and getting alittle snapper lawn mower and that is 30" wide and attaching some cultivators on it and doing one middle at a time lol. It will take forever but I have plenty of time because I just work weekends and off all week. Is there any other tractors that narrow or do you have any other ideas? It's gotta be something I can ride. lol
