Abstract: A system for performing several functions in caring for crops such as vines grown in rows uses a high pressure water jet to selectively prune, thin shoots and remove leaves from growing crops. Water jet size, pressure, movement and position relative to the crops are controlled to obtain desired functions.

Abstract: A crop picking head assembly has a known oscillation generating head supported in a head support frame suspended from a harvester framework by two pairs of depending arms. One pair of arms is variable in length to adjust picking head height and the other pair is fixed in length. The picking head has a variety of crop contacting rod arrays to accommodate various cordon types supporting extended rows of crop foliage, such as grape vines. The harvester may carry one such picking head on one side of the vine row or may carry mirror image heads, one on each side of the vine row.

Abstract: An inexpensive and readily available pruning blade for pruning crop growth, such as grape vines following harvest, has a disc-like base plate. The base plate has ordinary small diameter radial Skil-saw blades mounted around the periphery. The saw blades are fixed rotationally on the base plate by a clamp and have a portion of the saw teeth extending beyond the base plate periphery so that rotation of the base plate induces cutting action by the saw teeth at the periphery of the base plate. When the extending saw teeth become dull, the clamp is loosened, the saw blade is rotated through an arc sufficient to expose sharp teeth at the base plate periphery, and the clamp is tightened.

Abstract: An improved gondola assembly for receiving harvested crops in the field from a crop harvester has a lightweight molded drop in tank held in place by a tank framework on the gondola assembly. The drop in tank lowers the gondola center of gravity as it replaces stainless steel or painted mild steel tanks and requires no periodic maintenance. A built in scale for continuous in the field monitoring of the weight of received harvested crop is constructed to be viewable by a tow tractor operator whether towed from one end of the gondola or the other. The towable gondola obtains power for operation of a pair of tank framework lift cylinders from the tow tractor so that the tank is movable between an elevated dump position and a lowered crop collection position. The gondola has a reversible towing tongue for towing in either direction so it may be configured to be towed on either side of a crop harvester.

Abstract: A tractor for over the row in line towing of a trailer along a row of plants, wherein either the trailer or the tractor itself has the capability of carrying mechanisms for performing certain operations on a row crop. Such mechanisms include crop harvesters, plant pruners, plant sprayers or device for tilling the ground adjacent the plant rows. Use of these mechanisms in sloping fields is specifically envisioned. A portion of the tractor is designed to carry these mechanisms and is maintained in a level configuration in fields of row crops without substantial elevation of the tractor center of gravity. The main elements of the tractor are kept near ground level for easy access in all types of row crop terrain, sloping or otherwise, so that fueling and maintenance tasks may be readily performed and ground access to an operator's station is always available.

Abstract: An array of foliage contacting rods having a certain stiffness and trunk contacting rods having a greater stiffness is assembled in combination for mounting on an oscillatory shaker head configured to be carried over row cultivated crops by a mobile harvester to effect crop harvesting by both foliage shaking and trunk shaking using a single shaker head. Moreover, the number of rods of each type may be varied to suit harvesting conditions while the oscillatory shaker head remains in place in the mobile harvester and the stiffness of each rod is adjustable within limits to further conform to harvesting conditions. The rod array in one embodiment provides simultaneous harvesting of multiple rows of a crop cultivated in parallel row configuration.

Abstract: A self-propelled mechanical harvester for harvesting above ground crops includes a shaker assembly that operates in a single plane. The shaker will oscillate from side to side in the plane without pivoting of the plane around a pivot point. The assembly includes crop contacting rods in one embodiment and crop contacting striker bars in another embodiment. The force used to impart the oscillatory motion to the shaker is supplied by a force balance shaker using two weights operating at the same frequency of rotation, in opposite directions. The weights are timed and maintained in time by a geared relationship to produce maximum force laterally outboard and no force in a direction corresponding to the machine's direction of travel.

Abstract: A harvester for tree borne fruit is disclosed wherein a power driven vehicle is provided for following a course adjacent and parallel to a row of fruit trees. The vehicle carries a vibratory brush having tines for engaging and shaking the tree's fruit bearing branches. The brush is yieldably held in engagement with the fruit bearing branches and is adjustable in three aspects, elevation, tilt angle and lateral position, to assume an optimum position relative to the row of trees. A brake is provided to control a net rotation speed of the vibratory brush within the branches. A resilient screen deflects randomly projected harvested fruit toward a harvested fruit catch apparatus. The tines are covered with an optimally designed resilient cover for reducing cullage in the harvested fruit.

Abstract: A harvester for harvesting fruits from plants such as trees or bushes. The harvester uses a shaker head, which rotationally oscillates a vertical brush. A shaker frame is able to rotate around a wide arch which allows more than half the tree to be reached in a single pass. The other half of the tree may be reached by the brush in a pass in the opposite direction. The harvester also uses lifts to raise the brush to a height suitable for harvesting fruits from trees.

Abstract: A harvester for harvesting grapes or other fruits from plants. The harvester uses elastomer spring to support the closure wings of the harvester. The elastomeric spring may be a block of elastomeric material connecting a closure plate to the frame of the harvester. The elastomeric spring allows movement of the closure plate in many different directions. In addition, the elastomeric spring has fewer parts and is easier to assemble than conventional spring systems.
