 Hi, I'm John Arena from Arena Farms. We're located in Concord, Massachusetts. We grow 180 different varieties of fruits and vegetables on 200 acres of land. We currently are in the process of using a lot of machinery for cultivation purposes, sort of to get away from the use of herbicides and with minimal hand-weeding. We grow many varieties of beans and peas all with out herbicides. What we do is, in that particular field, we try not to let weeds develop, go to seed. So we're constantly keeping that process of howling, cultivating, keeping those weeds from going to seed as a big part of our farm plant, our farm weed plant. That process is done by planting the grows, we plant them three feet apart. Leaving a hill of dirt on each side of the row helps us to, when cultivating, it fills in along the stem of the plant and covers any small weeds that might be germinating and generally in the about six acres of beans and peas we grow, we can do all of that without any hand-weeding and just cultivation. This tractor is set up with cultivating discs for doing along the edges of plastic without the use of herbicides and very minimal hand-weeding. This is set up with a straight tooth right here. It's at a slight angle to get underneath the black plastic. It also kind of lifts it up a little bit. So any weeds that are germinating or small weeds that are there get, you know, really get disturbed by that followed by a second round cultivating disc, which again throws dirt out and disturbs the weeds. And the last disc here returns the soil back onto the plastic edge where this first one kind of had taken it off a little bit and this is our all these tools here are simple cultivating tools, a straight tooth that does have a spring behavior if you have rocky fields. The tractor is a super-sea farm all from International Harvester and and very simple operation. We generally use this machine when weeds are about just just starting to germinate. That's the best time to go in. That slight disruption of the ground when small weeds they die instantly. If you do get behind, however, and weeds start to germinate and they get even up to six, we've even used this at 12 inches in height. Because the round discs are there you get no clog up. That you would normally get on all straight teeth. So it's great if you can get in early and if you happen to not get in early, they still will do a great job. The only difference is you'd have to do a weed six to twelve inches in height. You may have to do your rows six, about six times to get a complete clean area. Whereas if you get in at the right time, usually twice a year is all that you need to be done. This particular field has been done twice and what offers us, also with this unit, is we can put down fertilizer at the same time that we're cultivating. So it looks like we're getting a lot of things done with one pass. This cultivation system also works great on crabgrass. It gets down below the root system, lifts it out and it does kill it. The purse lane also, which generally is a problem weed for us, it does pull the weed out and if you do it on a hot enough day, it generally will die before it has a chance to re-root itself in.
