Tomato harvester

Claim 2

In a row-crop harvester for tomatoes and the like having crop-severing means, crop-elevating means for picking up the severed plants and lifting them well above the ground and depositing them in a separator where the fruit is received from the stalks and leaves, a spinner adjacent to the forward end of said crop-elevating means in an operative relationship between said crop-severing means and said crop-elevating means, said spinner being characterized by comprising a central support shaft and a unitary molded elastomeric member molded about said shaft as a single integral member having a series of flat paddle portions extending out in respective radial planes from a central generally cylindrical core, each paddle portion being connected to the next adjacent paddle portion by a smoothly curved radius bridging portion at said core, the outer edge of each said paddle portion having a smoothly undulating edge with radius turns at each change of direction.

Claim 3

A row-crop harvester for tomatoes and the like having crop-severing means, crop-elevating means for picking up the severed plants and lifting them well above the ground, plant shaking means for shaking the lifted plants and thereby separating the fruit from the stalks and leaves, including in combination therewith a fruit-collecting conveyor moving lengthwise of said harvester beneath said plant-shaking means for collecting the separated fruit and conveying it, and comprising a pair of endless chains on opposite edges, a series of rods extending laterally between said chains and secured thereto, an identical pair of hydraulic motors, one for driving each said chain at the same rate and drivingly connected thereto, said motors being in series in the same hydraulic conduit system, a relief valve in series with said motors connected by a return line to the fluid supply for said hydraulic conduit system, and means in said return line for actuating an alarm system upon the pressure in said return line reaching a predetermined value.
