Low-Tunnel Layer Machine

This tractor-towed Low-Tunnel Layer Machine (Model 95) sets the wire hoops, lays the plastic over those hoops, then disks soil over the edges of the plastic-all in a single pass. A person (seated) simply feeds the wires into the unit and monitors rollout of the plastic. Three models are available-NARROW (5-foot-wide plastic/12-inch-high tunnel); STANDARD (6-foot-wide plastic/14-inch-high tunnel); and WIDE (7-foot-wide plastic/18-inch-high tunnel).

Cost: $8,295, depending on model
