Moss Peat Cutting Machine
Type – Klasmann
This machine cuts the bog 0.8 metres deep and 0.8 metres wide in the form of sods. It inverts the sods in the lifting motion and transfers them onto the high bog, building them in wall form and leaves ventilation space between the vertical sides of the sods.
The machine is fully tracked with light frame and supports the cutting, transporting and wall building mechanism at the rear. The cutting mechanism consists of a knife, the full width of the cut, with a central pin to divide the section, operates up and down in a plane slightly of f the vertical. The slides in which the knife operates are supported on a cradle which moves backwards while the knife is on the downward stroke to compensate for the constant forward travel of the machine, and forward when the knife is almost fully raised so that it takes up the position for the next cutting stroke.
The dicing and lifting mechanism operates on a fulcrum just above ground level with the fulcrum axis at right angles to the bank. Arms extending from the fulcrum carry six cutting plates. When the knife reaches the bottom of its stroke this frame of dicing plates swings downwards dividing the section into five sods on the depth of the cut making ten sods in all. The upward swing of this frame lifts the sods, held between the plates, through half a revolution leaving them flush with the cross' slide. The top layer of the bog, not held between plates, is thus not lifted but falls downward as the mechanism moves away and is caught by a bucket which swings in to receive it and swings outwards to discharge it in the cutaway.
The transporting mechanism is also frames fitted with spikes which swings downwards embedding the spikes in the two sets of five sods sliding them across the rear of the machine onto the discharge table. The two sets of sods are separated in the cross movement.
The discharge table after receiving the sods swings backwards on a fulcrum at its base and in doing so re¬arranges the sods in stair-form as it places them on the previously arranged sods.
The machine is powered by diesel engine and the trans¬mission is by gears, roller chains, cams and linkage to the various operating parts as described.
The special feature of the machine is good ventilation and the placing of the sods in the wall in the reverse order as cut, in the bog face, thus placing the firmer and drier sods at the base of the wall.
A well appointed cab overlooks the cutting and discharge mechanisms.
