A warehouse system employs a crane guided for movement along an aisle with storage racks on opposite sides thereof and mounting a carriage for vertical reciprocation thereon. An extractor supported on the carriage has a pair of narrow extensible arms which engage the undersides of lips formed on opposite sides of a tote pan. The extensible arms each include three rails nested in one-above-the-other relation with the intermediate rail having vertical load bearing rollers engaging the upper and lower rails. A harmonic drive causes extension and retraction of the extractor arms through a chain and pulley arrangement. The tote pans are nestable and have ribbed bottoms cooperatively engaging cantilevered brackets on the storage racks whereby the pans are releasably detained in their stored position in the warehouse.

The disclosed grass catcher cooperates with a rotary mower carried under a riding vehicle and having a clipping outlet from which a duct extends upward and rearward along the side of the vehicle for discharge into upwardly opening bags supported side-by-side at the rear of the vehicle, each carried on an upwardly and rearwardly projecting hook that enables quick and easy removal and remounting of the bags. Clippings issue from the duct in a trajectory that tends to carry them across the width of the vehicle, but they are deflected downward to fill the bags successively. Such deflection is effected by a cover that overlies the bags and the discharge portion of the duct and has a baffle projecting down from its top wall which defines a divergent air channel leading from the duct outlet and under which air blown up through the duct from the mower is diverted in flowing to a screened rear air outlet in the cover. The outlet portion of the duct is readily removably held in place by an elastic band. Without disturbing the duct, the cover can be swung forward from its operative position for easy access to the bags.

A mobile agricultural harvester has a crop header at its forward end including a plurality of crop dividers. The crop dividers each include a forwardly tapering point portion terminating at its forward end with a tip. Either the tip or the point portion or both are constructed of light emitting material, or are provided with windows covered by light emitting material, so as to provide improved illumination of the crop and field in front of the header during a harvesting operation.

An Agricultural combine having a sickle reciprocated by a wobble drive mechanism and a torsion bar coupled to the sickle to reduce the input torque requirement of the drive mechanism, is provided with a warning system to operate an alarm when energy is still stored in the torsion bar, unknown to the operator, when the drive mechanism is shut down and which stored energy could reciprocate the sickle and represent a hazard to the operator. The hazard warning system is disabled when the drive mechanism is operating.

In order to provide a higher cutting speed for a high speed harvester (11) torsion bars (31, 68) are connected to opposite ends of a crop cutting sickle (28). A pair of levers (46, 62) which connect the torsion bars (31, 68) to the sickle (28) carry a pair of removable counterweights (56, 96) which can be sized to change the resonant frequency to substantially correspond to the desired cutting speed. The levers (46, 62) may be interconnected by an adjustable tie bar (111) for hard to cut crops which is of sufficient mass to replace the counterweights; or, counterweights (156, 196) may be added to adjust the resonant frequency and hence the resonant cutting speed.

The body structure 12 of a rear engine riding mower 11 is resiliently mounted on a main frame structure 13 by four cushion mounts 14. The engine 48 and steering shaft are mounted on the main frame structure 13 and the operator's seat 53 is supported on the body structure 12. Each of the mounts 14 is provided with a restrainer in the form of an inverted cup 69 which serves to stiffen the mount when the body structure 12 shifts horizontally (see FIG. 6) relative to the main frame structure 13 and when unusual vertical loading (see FIG. 7) is imposed on the mount.
