A harvesting machine for nuts and stone fruits including an articulated body with a front part and a back part. A tree shaker head is detachable and couples to the front part of the harvesting machine by a C-frame mount. The articulated body with a low clearance provides necessary maneuverability in an orchard environment, while permitting the harvesting machine with the shaker head detached, to function as a general purpose orchard machine for mowing, spraying, brush clearing and other associated tasks. Specialized machinery for these tasks is no longer necessary.

Surfaces treated with a ceramic roof coating (CRC) marketed as AZTEC No. 100 were compared to untreated and white painted surfaces. Dry-bulb and black globe temperatures in the space below or behind the surface were the criteria for comparison. Comparisons included small horizontal panels with open sides, small unvented galvanized steel and styrofoam boxes, and an open-side steel poultry building. The CRC was effective in reducing temperatures in the enclosed test boxes, but less effective with open-side test panels and the open-side steel building. Tests also indicated the CRC is characterized by high emissivity (0.95) and reflectivity (0.87). The evidence …
