Abstract

A Flail System (12) for a terrain clearance vehicle (10) is disclosed which comprises two flail axles (14) which extend laterally in fron of the veicle (10). Each flail axle (14) carries an axially-distributed array of flail chains (20) and has two sets of mounting arms (16, 18) on which the axles (14) are rotatably mounted. The mounting arms (16, 18) also incorporate means (28) to maintain each flail axis (14) at a controllable height above the terrain. The mounting means (16, 18, 22, 24) are arranged such that the flail axles (14) can be held either substantially parallel to the terrain in a terrain clearing configuration. They may also be folded upwardly into an inactive configuration so that the overall width of the vehicle (10) and flail system (12) is substantially less than the overall width of the flail system (12) when in the terrain clearing configuration.
