 I'm Tom Harlow, I'm the owner and operator of Kestrel Farm here. We bought this farm this past year, it's about 90 acres, certified organic. We are growing vegetables on about 50 acres of it, the rest of it is fallow or past year. This is in Westminster, Vermont. It's wholesale, probably 85% of it. The other 15% is retailed through a farm stand that we are partners in with my brother, actually two brothers. This is a flame weeder that I used at Paul Harlow bought five or six years ago for about five to six thousand dollars. It runs on vapor rather than liquid. It was custom made in Germany to fit the four foot wide beds that we were planting at that time. We use it for raised beds for carrots and parsnips mainly. It's used in carrots and parsnips on a stale seed bed which gives us at least a 50% reduction in weeds that need to be hand pulled. We make a stale seed bed about a week or ten days later we roll the top of the bed then we plant. And just before the emergence of the crop, we run the flamer over to kill small weeds of a quarter to half an inch in height. It works really well on broadleaf weeds. It does next to nothing on perennial weeds or grasses. Okay, this is a vapor system has four of these 20 to 25 pound tanks that go in this reservoir of water. This tank is a reservoir filled with water which is heated by a small burner which keeps the water warm and keeps these tanks from freezing. Because we use the gas at such a high rate that these tanks would freeze up and gas is no longer available if it freezes up. There are shutoffs on each tank. There is a shutoff inside the control panel which shuts off the gas. There is an electronic shutoff for the burners and the pilot. Six burners across this four foot space producing, I don't know what kind of BTUs but very hot. In dry conditions I can travel at about six miles an hour doing a very good job. Early in the morning if the weeds are wet with dew, I usually shift down to about four miles per hour. The disadvantage to this machine is that it's set up for the four foot wide bed and it's not adjustable. The burners are all attached rigidly, they can't be turned off, they can't be adjusted to different angles. So we're stuck with this four foot wide width. Since this was made we've gone down to about a two foot wide bed which means that we're actually only using about half of the burners. Generally this uses about $32 worth of gas per acre which is $8 per tank which is what it costs us to fill these up. Under dry conditions we use a little less gas because we're traveling faster. In wet conditions we use a little more gas because we have to travel at a slower speed. This is a roller that comes from off the back of a field cultivator. The brackets have been cut off and we just mount it mid-mount underneath this tractor. It's ground driven, it rolls very freely. We use this in the initial preparation of a stale seed bed. Subsoiling first and then coming back with this roller to make a nice smooth and level seed bed. Then about a week or ten days later we come back and hit the beds with this roller to kill any small weeds that have germinated just before we plant. Another very important thing to remember about tilling your stale seed bed with this is that you don't want to go so deep that you're bringing up new weed seeds. So we try to go no more than two inches deep with this. We also travel very fast to get a good stirring of the soil.
