Hand raking was compared to a non-mechanized machine and to two self propelled harvesters for yield and harvest time. Experimental design was split-plot replicated six times with four harvesters/plot with each raker using each machine in each plot. The machines were operated adjacent to one another. Hand raking resulted in the highest yield recovery of all harvesters. Average yield varied by raker from a high of 4831 kg/ha to a low of 3884 kg/ha. The Bluevester harvester recovered 91% of hand harvest and was 1.6 times faster than hand raking while the Darlington machine harvested one half of hand harvest in one quarter of the time. The Easy Pick recovered 81% of hand harvest but was twice as fast. Mechanical harvesters took less time but recovered fewer berries. A economic analysis is needed to fully evaluate these machines.
