It's been 8 years now since we first prototyped the Buddingh Plastic Mulch Trim Cone with the help of several growers. They are still selling and this year they cost $400.00 each plus shipping. This includes the 1-1/4 inch solid mounting shank.
60 degree wires are the most popular and work for most farms. If you have those high wall 75 degree (15 from plumb) walls you would need the 80 degree wires. If your laying the plastic on the ground flat more or less the 45 degree wires would be most practical. It is helpful to email a picture of your beds to be sure.
We believe these to still be the most aggressive design out there to work right up tight to your plastic. To maximize your width of cultivation the working radius of the wires should be up on the outboard side about 3/4 of an inch. The idea is to have the inboard side set the spin so it wheels along the plastic without picking it up. The forward edge should also be tipped up slightly so the working pressure drives upwards against the phenolic bearing shoulder. If 12 o'clock is straight ahead your looking at 2 o'clock on your RH and 10 o'clock on your LH as the furthest points out of the ground.
