Abstract

1,139,679. Woodworking. E. POWELL. 21 Sept., 1967 [21 June, 1966], No. 27714/66. Heading B5L. Apparatus for clearing tree stumps and/or roots of felled trees comprises a rotary cutter or cutters 7 carried by supporting means comprising a swingable articulated arm structure operable to permit the cutter or cutters to be moved to demolish the stumps or roots by cutting. The arm structure consists of an arm 1 at one end connected by a pivot 13 to a turret 14 rotatable about a vertical axis, and at the other end connected by a pivot 6 to an arm 2 carrying at its outer end a cutter comprising a pair of spaced discs 7 mounting replaceable cutters 8. The cutter is driven by a chain 11 from an hydraulic motor 10, and hydraulic rams 15, 22 are provided for raising and lowering the cutter and for extending and withdrawing the arms 1, 2. A further hydraulic motor is provided to rotate the turret. The apparatus may be mounted on the platform 29 of a vehicle and operated pneumatically, electrically or mechanically instead of hydraulically.
