25 kg/pers
Mushrooms grow on five tiers of shelving and every one is plucked off the bed by hand. Nothing moves but the pickers.

A blade and a belt boxed up on wheels. The machine drives along a shelf from right to left, shaving the mushrooms off the bed as it goes and carrying them away inside.
35 kg/pers
The same growing rack, now with a belt slung on two cables. It is winched up and down to sit level with whichever shelf is being picked, and what is picked goes straight onto it instead of into a basket.
35 kg/pers
Ten mushrooms at a time ride the belt with their stems through the slot; a horizontal blade takes the stems off in one pass.

50 kg/pers
Whole lumps arrive on an indexed belt; the cutting box harvests each lump in one stroke and sets the mushrooms on the take-away belt.
200 kg/pers
Eight lumps cut in a single go; the loose mushrooms drop into boxes of four and head to packing.

1000 kg/pers
No more lumps: an unbroken stream of compost rides a thirty-degree belt while a skimming knife shaves the mushrooms off mid-flow.
