Abstract: The invention relates to a drive for a straddle type berry harvester suitable in particular for harvesting raspberries. The harvester has a frame mounted on wheels movable over a row of berry plants and having opposed rotatable upright cylindrical tined shakers connected above by universals to output shafts of a drive and mounted above conveyors in laterally slidable bearings to avoid obstructions in their path. Spring-mounted interleaved deflector plates lie between and beneath the shakers inclined towards the conveyors to guide berries shaken off by the shakers and falling therebetween. The shakers are rotated by cooperation of the tines with the plants as the harvester moves thereover.The drive for the shakers consists of two vibrating head assemblies and a high speed input in each assembly driven in synchronization but in opposed rotary direction by a single high speed prime mover.
