catch plates (also called fish scales) at the base of the machine. These losses often have reached 20% to 30% with machine harvesting ( Mainland, 1993 ; Strik and Buller, 2002 ; van Dalfsen and Gaye, 1999 ). Excessive green and red fruit detachment

base-pruned to remove small-diameter twigs and canes that would potentially interfere with the catch plates on the harvester. In the center of each plot, four uniform plants were marked for subsequent yield measurements after MH. Four plants at the

canes, other fruits, and interior surfaces of the harvester or catch plates while falling through the bush after detachment ( Takeda et al., 2008 ), and as fruit moves from the catch plates to the lugs ( Yu et al., 2012 ). Harvest losses may occur due to

Free access

spiked-drum shakers that rotate freely and cause fruit to drop ( Funt et al., 1998 ). Fruit fall onto a catch plate, roll into cups, and are conveyed vertically to a cleaning and sorting belt at the top of the harvester. Sorted fruit are collected in

16-ft between-row and 4-ft in-row spacing, and were trained to a three-wire trellis system with the lowest wire 2 ft above the soil surface to accommodate the mechanical harvester’s catch plate. Harvest method (hand and machine) was randomized with

harvesters who use handheld shaking devices. Some of these platforms have modified catch-plate surfaces to lessen the impact of berries falling on this hard surface once detached from the bush. These platforms and modifications could make harvest faster

’s catch plates then are conveyed into bins. A shake-and-catch harvester is a combination of two self-propelled units—a trunk shaker and a matching catch frame. An example of this harvester ( Brar, 2020 ) is shown in Fig. 1 . The trunk shaker clamps to the
