Improved agricultural apparatus including a three-point hitch frame for attaching to a vehicle and to a tool bar assembly. Three-point hitch frame includes L-shaped retaining members for engaging the tool bar assembly and may be substantially U-shaped. The invention is also embodied in an agricultural apparatus with a hitch frame for attaching to a vehicle and to a tool bar assembly and including a metering hopper system attached to the upper side of the hitch frame. The invention is also embodied in an improved ground contact metering wheel assembly for maintaining contact with the ground even on uneven terrain. The present invention has particular applicability as an interseeding apparatus.

Agricultural apparatus

A harvester adapted for harvesting low-lying fruit, such as typical with high-density, dwarf trees, includes an intra-loop conveyor for collecting detached fruit relatively close to the ground and elevating same with a single flighted belt. The harvester straddles a single row of the trees and detaches the fruit therefrom by repeatedly impacting the tree canopies are the harvester moves along the row. Spring-loaded deflection plates close around the tree trunks and deflect detached fruit outwardly to interior surfaces of a pair of single-loop conveyors. Baffles cooperating with the interior of each conveyor restrains fruit therein as the conveyor passes overhead to an inverted position. Fruit is discharged from the conveyor elevated segment onto an output conveyor passing beneath the discharge area. The output conveyor includes a multi-segment, foldable conveyor frame over which a single conveyor belt is entrained. The conveyor belt may be folded over the harvester during non-harvesting transport. Canopy-impacting tines function as fruit detachment devices, and are rotatably driven in a single plane with both constant rotational and oscillatory rotational components of motion. The constant component is synchronized with vehicle forward speed to permit unimpeded feeding of trees through the harvester. The superimposed oscillatory component causes tines to sharply impact tree canopies for detaching fruit therefrom. Both the amplitude and frequency of such impacting action may be varied.

Harvesting machinery

A multipurpose horticultural crop tractor combines certain clearance and versatile implement mounting features for accommodating a wide variety of alternative field production operations. A movable operator station provides full bidirectional operator control. An operator station may also be suspended on a boom pivotably mounted to the tractor frame for repositioning of the operator station about such frame. The implement mounting system also permits alternate high or low clearance mounting of a conventional three-point hitch, which when used in an elevated position enables attachment of high crop harvesting heads. Alternative implement mounts permit simultaneous usage of two separate implements. The tractor may be outfitted for many alternative functions, such as tillagae, planting, cultivating, spraying, harvesting, materials handling, and irrigating missions, including usage of a vertically movable lift unit with horizontally adjustable lift arms.

Orchard fruit handling apparatus for conveying and delivering harvested fruit into a plurality of storage bins comprising a first conveyor for adjustable attachment to a conventional farm tractor for receiving and transporting fruit received thereon in a generally linear direction rearwardly of the tractor, and trailer means for attachment to the tractor containing a second conveyor for receiving harvested fruit from the first conveyor and selectively directing the fruit into a plurality of storage bins carried on the trailer. A plurality of deflecting blades or bars are selectively positionable across the second conveyor to selectively intercept and deflect the fruit into corresponding bin filler mechanisms located along the side of the second conveyor and above corresponding collection bins. Each bin filler mechanism forms a sinuous passageway for gravitationally directing the fruit downwardy into a collection bin and is vertically positionable to maintain its lower fruit discharge outlet at the upper level of the fruit being collected in the storage bin. The trailer is provided with means for gravitationally discharging the filled fruit storage bins on to the ground at a central location in the orchard, and the orchard fruit handling apparatus is powered by connection to the hydraulic and electrical systems of the conventional farm tractor.

Orchard fruit handling system

Crop uprooting and cultivating apparatus which includes at least one bar having at least one angled edge thereon that extends from a support at least partially across a row to be cultivated or from which crops and/or foliage are to be uprooted. The bar is rotatably supported by a support structure in cantilever fashion, leaving an outer end of the bar free. The bar may extend across a crop row in a direction generally transverse to the direction of movement of the apparatus along the row, or may be angled rearwardly with respect thereto to provide a self-cleaning action. The bar rotates beneath the surface of the soil and uproots crops and foliage as it moves along, the direction of rotation being in a direction opposite the direction of travel of the apparatus. A pair of bars may be provided, one being located on each side of a row being cultivated or where crops are to be uprooted with at least one of the bars extending a distance of more than 50 percent of the width of the row. The outer free ends of the pair of bars may overlap. A hydraulic cylinder or the like may be associated with one or all bars to move same horizontally away from the center of the crop row and return same to its normal uprooting, cultivation location. With this arrangement, the apparatus may be utilized in a method for cultivation, the bar or bars being moved away from crop plants along the row upon sight or automatic sensing of the presence of the plant and thus uprooting foliage and working the soil only between the crop plants.

A device operable for engagement with selected tree portions to convert rotary motion to a linear shaking motion for use in a fruit harvesting operation. The tree shaker includes tree gripping elements with a motion converter operatively connected thereto, the motion converter including a rotary mass having an input drive thereto operable to displace the mass in a first direction with control means to effect a counter-rotation of the mass in response to the first direction displacement, whereby the combination drive control results in a linear reciprocating motion of the mass which is transferred to the associated gripping means for shaking the tree portion. The apparatus can include a single motion converter for use in shaking a tree or limb or a pair of motion converters for use in shaking a tree trunk or a large tree limb. When a pair of motion converters are utilized the control means is operable for driving both converter means at the same speed and in phase to obtain a constant linear reciprocating shaking motion, or is operable for driving the two motion converters at different speeds such that the phase angle between the two converters is continuously changing to provide a continuously variable shaking action.
