A pulling winch is used to flush mushroom beds. The manure beds on which the mushrooms are grown, lay on sheets of cloth. These sheets are rolled up and the manure is caught onto a conveying system placed behind the pulling winch. On the other side, a new sheet of cloth can be pulled inside. The axles that empty the multiple levels can be coupled separately, according to which bed you want to empty.
Mostly, the pulling winches are made fromstainless steel or zinc because of the aggression of the manure. Capacity up to 7 tons.
