Abstract, The presser wheel support comprises a depending support arm pivotally connected to the end of a cantilevered arm projecting at a downward slope in the tailing direction from a net hauler sheave frame member preferably in the form of a transverse suspension plate overlying the net hauler sheave. A fluid operated jack interacting between the hauler sheave frame and the support arm generally in the common plane of the hauler sheave and presser wheel urges the wheel yieldably against netting descending in the main hauler sheave groove so as to increase the hauling traction and hauling force exerted on the netting to avoid slippage and damage of netting.
