with diagonal braces at each corner of the house. We retained the crossbar on each hoop because we think it is necessary in a mobile house to keep the hoops from splaying when the house is moved. Also, the crossbars provide overhead structure so trellised crops such as tomatoes or cucumbers can be grown in the houses during the summer.
Making Greenhouses Move I discussed a number of different options for making greenhouses mobile in The New Organic Grower, including a ballcaster design and various skid designs. We have used all of them at one time or another. With A 48-by-22-foot house on 2-by-3-inch galvanizedour rocky soil it was extremely difficult to drive pipe skids.

a 90-degree angle to the handle, there were a few with smaller blades at an 80-degree angle, and they were somewhat more pleasant to use. Off to the workbench we went with a couple of sacrificial hoes and proceeded to cut, bend, and file. After repeated trips back to the fields to try them out we came up with a prototype with a narrow blade (7 inches side to side and 1 inch front to back) and with the neck bent to hold the cutting edge of the blade in line with the handle at a 75-degree angle. After further experimentation with many eager participants we determined that the optimum angle was 70 degrees. We also
