Abstract

Known peat harvesting apparatus for mounting on an agricultural tractor comprises (a) a digging chain for insertion into and movement across a bog so as to form a groove, and (b) a peat extrusion press. The invention provides; a method in which a groove (204) inclined to the vertical is formed, which is subsequently closed over by downward pressure of the tractor wheel (202) thereby conserving bogland; a roller (107) above the digging chain (104) to prevent the apparatus clogging; a single drive transmission connecting both digging chain (104) and extrusion press (105) to the tractor power take-off shaft; and a macerating mechanism in the extrusion press (105) which allows extrusions of relatively small cross section to be produced. <IMAGE>
