Interest in the development of forest utilization and woodworking industries is rejected in the continual demand for information on new equipment. The Forestry Division, TAO, collects such information and passes it, on request, to Member Governments: a selection is published here. TAO accepts no responsibility for the claims of manufacturers.
- This apparatus is a cheap and simple construction for sharpening posts. It consists of a metal conical body with a 12 in. (30.5 cm.) blade, 2 in. (6 cm). wide and ¼ in. (0.6 cm.) thick. Inventor: Mr. E. Salthouse, 25 Westbourne Road, Urmston, Manchester, England.
- The single cage wheel prevents veil consolidation caused by the tractor wheel. It can be bolted to the side of the tractor wheel and the diameter is designed to allow the cage wheel and tyre to take the weight of the tractor, while keeping the pneumatic wheel from panning into the land. The double cage wheels illustrated here completely replace tractor wheels and are well suited to bog and swamp land.
