Abstract: The invention provides an outlet for a peat extrusion press, the outlet comprising a pair of jaws which in the closed position thereof co-operate to define a number of side-by-side extrusion pipes and in the open position define, in place of the pipes, an unrestricted outlet. If the extrusion pipes become clogged during operation, the jaws are opened to release whatever is causing the clogging, and are then closed.

Abstract: On a known peat harvesting apparatus for mounting on an agricultural tractor comprising (a) a digging chain for insertion into and movement across a bog so as to form a groove, and (b) a peat extrusion press, a roller (107) is mounted above the digging chain (104) to direct harvested peat into the press and prevent the apparatus from clogging. A single drive transmission connects both digging chain (104) and extrusion press (105) to the tractor power take-off shaft. A macerating mechanism is provided in the extrusion press (105) which allows extrusions of relatively small cross section to be produced.
