    Abstract: A hood assembly includes a hood member and an adjustable length stabilizing link. The stabilizing link is movable between a first position at which the link maintains a bottom surface of the hood member in a substantially parallel relationship with a ground, or soil, surface and a second position at which the link tilts, or rotates, the hood member and thereby moves the bottom surface of the hood member to a nonparallel orientation with the ground surface. When in the tilted position, a portion of the bottom surface of the hood member is spaced from the ground surface at a distance sufficient to permit access for the repair or service of elements normally protectively enclosed by the hood member.

  • Patent number: 5067264
    Abstract: The flexible tiller has a center and two end sections, each including a cutter bar, frame, apron and grooming bar. The two tiller end sections are connected flexibly to the ends of the center section by frame to frame hinges and by cutter to cutter universal joints, so that the end sections can rotate freely about the hinges. The tiller center section is secured to the towing mechanism to oscillate about a central horizontal axis in the direction of travel. The oscillating center section and the two pivotally attached end sections cooperate to enable the tiller to closely conform to and thoroughly groom rolling snow paths without reducing them to flat ones. The rolling paths are enjoyable to ski, and are slower and safer. A controllable hydraulic ram is mounted to act across each hinge, so that the operator may select the degree of bending permitted at each hinge, and may hydraulically lock it into selected position, if desired.

  • Patent number: 4616715
    Abstract: A rotation control system for the mattock (2) of a tuft-building forest mattock, whereby rotation of the mattock is adapted to be braked or stopped stepwise in a manner that each pick (3) in turn works a whole in the first stage, in the second stage the pick (3) of the mattock removes surface deposit from between the obtained hole and a tuft to be built, and in the third stage, as mattock (2) is allowed to rotate freely, pick (3) leaves the loosened earth behind as a tuft. In order to make the sticking angle and depth dictated by the start moment of braking stages readily adjustable according to various qualities of soil, at a certain angle of rotation of the mattock a first impulse sensor actuates a first delay timer (6), adapted after a settable delay time to turn on a brake (11) for setting out the first stage of the mattock (2).

  • Patent number: 4331204
    Abstract: A tractor drawn tillage implement having a front hood, rippers, a rotary tiller and a row former, conditions tight adobe soil ready for planting in one pass. The front hood, having rock deflectors, protects the operator from airborne objects while containing dust and soil disturbed by the rippers and the tiller. The rippers fracture the soil to aid water and root penetration, to increase water retention of the subsoil and to constrain development of hard pan. The rotatary tiller, driven by an auxiliary power unit and having its axis of rotation at or submerged below the ground surface, mulches the soil and plant residue and aerates the soil commensurate with rearward airborne discharge of the soil. A row former deflects the airborne soil into rows of predetermined height and width ready for planting and provides an air tight shroud to control dust and airborne objects. A tool bar is also incorporated for supporting add ons, such as fertilizers and planters.

  • Patent number: 4267891
    Abstract: A cultivating machine has groups of soil working tines that are mounted on an elongated support that is driven to rotate about a horizontal axis. The tines are mounted in spaced apart groups and guide members converge at the rear of the groups to form ridges of worked soil. Each group includes tine units that are formed by opposing bracket portions clamped to the support. Strikers can be mounted on the support between groups of tines and the strikers are pivotable about respective horizontal axes spaced from the support's axis of rotation. The strikers are positioned to excise crop leaves or emerged growth on the ridges. Hoods and a grating ensure that the top layer of worked soil is free of debris. Screening plates having obliquely upwardly and inwardly inclined inner edges are located at the lower, front, outer corners of the hood to prevent the rearwardly adjacent time groups from displacing soil too far laterally.
