In 1963/64 our village cemetery got a Multigardner unit,with a sticker on it "Farmfitters Ltd, Gerrards Cross, Bucks England"
It consisted of an Aspera LAV 30 / 35 mounted on simple frame which consisted of the handlebars, extended under the engine, to which the engine was bolted, and had a single bolt bracket for clamping it on to a choice of cutter frames or other tools.
We had the 18" rotary mower frame, and a small 10" cutter frame for cutting in narrow spaces between graves.
The 18" cutter had a triangular plate onto which 3 x small reversible triangular blades were bolted, and a circular shield.
The 10" cutter blade was a single broad reversible bar, and the shield was clearly related to the one in this picture, being the same design and colour.
The height adjustment knob / rod, and wheels looks identical to that on the 18" cutter, which has long since gone.
I am sure this is from the same family.
We still have the 10" cutter, and the handlebar frame, and the incomplete remains of the second engine.
