It is a bit useful, TS.
I bought 80 dumpy bags full of firewood during the summer for myself and three of my neighbours to burn over winter, I've already managed to put my back out pulling the bags into a transport box on the back of the Fergy --- hence the need for the crane.
The original exhausts were underslung on the Fergy, the upright exhaust was an optional extra which later became a standard fitting.
All the best Mick
