摘要:
A suspension system for the rear axle of a self-propelled agricultural windrower. The axle is split into two components, each having an air spring to absorb shocks. The two air springs are interconnected by a tube to equalize the internal pressure. A pair of pins can be inserted through the respective axle components and a structural member of the tractor to fix the components relative to the unit structure, thereby incapacitating the suspension and permitting effective steering of the tractor in the absence of a header.

A curved implement tongue improves the turning characteristics of the implement, such as a mower-conditioner. The tongue is bent in the horizontal plane and incorporates a generally vertical box section at the end of the tongue. The tongue supports a driveline transmitting rotational power from a prime mover to the operative components of the mower-conditioner.

The invention relates to an improvement to the header of an agricultural self-propelled windrower. The invention has a conditioner assembly and mower assembly that can be separated and removed. Hook and pin combination and a conditioner mounting bolt attach the conditioner assembly. A free link and bell crank allow the flotation springs to remain attached with the header is removed. A header top link can be attached to a bracket on either the conditioner or mower assemblies to assist in moving the header. There is a header lift manifold that moves a restricted flow control valve by a switch-actuated solenoid. When the solenoid is activated, the valve moves and forces hydraulic fluid through an orifice. This allows the header limited movement.

A modular disc cutterbar utilizes self-contained cutter modules clamped between alternating spacer modules by fasteners engaged with the spacer modules. To resist bending moments in the cutterbar, selected fasteners can have a length to span more than one cutter module. The drive mechanism is also of a modular construction including a symmetrical, reversible sealed drive apparatus within each cutter module and a transfer shaft passing through each interstitial spacer module to interconnect each cutter module drive mechanism. The drive apparatus incorporates an oil slinger to keep the remote seals lubricated. The rock guard for each cutter module is mounted on the adjacent spacer modules, while the skid shoe mounting is simplified. A crop mover mounted on each disc member above the cutting knife improves the transfer of severed crop material. An oil slinger mounted on the drive assembly within the cutter module draws oil from the reservoir past the adjacent bearing and disperses the oil onto the corresponding seal member for lubrication and cooling thereof.

A sealing apparatus is provided for a pivot assembly on a disc mower incorporating a disc cutterbar to sever standing crop material by impact action. A first circular labyrinth seal has a T-shaped cross-section and fills a correspondingly-shaped groove between the pivot support arm and the gearbox housing. The combination of the T-shaped groove and corresponding labyrinth seal creates a labyrinth path for the entrance of dirt into the pivot assembly. A second circular face seal is constructed with a deformed inner diameter to create a lip that engages the face of the gearbox hubs. The deformed inner diameter lip of the face seal creates an inner cavity underneath the seal that can be filled with grease to provide a further deterrent to the entry of dirt into the pivot mechanism.

A telephone line connector for location between a telephone and a plurality of outlet sockets and in which the connector is connectable to a power cable. The connector has a plurality of input signal sockets and a common signal and power output socket. A pair of power input terminals are connected to the common socket. The common socket also has pairs of signal output terminals connected in such a way that the connector through the input signal sockets is connectable to a plurality of wall outlets, each of which may have a single pair or a plurality of pairs of lines connected to it. The connector is thus capable of transferring all of those lines, as required, to a telephone together with power.

An agricultural machine such as a mower conditioner includes a cutterbar carried by a header that is suspended from a frame. The cutterbar has a plurality of individual cutting units with two end cutting units located adjacent opposed sides of the frame and intermediate cutting units disposed between the end cutting units. Each cutting unit consists of blades pivotally mounted on a rotor. A tongue adapted for connection to a tractor is pivotally connected to the frame intermediate the opposed sides thereof. Input drive shafts deliver power from a power-take-off shaft on the tractor to a pair of generally vertical output drive shafts via a bevel gearbox and a spur gearbox. The generally vertical output drive shafts are connected to two of the intermediate cutting units, and generally horizontal output drive shafts connect these two intermediate cutting units to the other intermediate cutting units and to the end cutting units.
摘要:
A disc mower-conditioner having a disc cutterbar with transversely spaced rotatable disc cutters to sever standing crop material by an impact action and a rotatable conditioning mechanism mounted rearwardly of the cutterbar to receive and condition severed crop material is disclosed wherein each disc cutter is provided with a crop lifter affixed to the peripheral portion of the disc cutter adjacent each knife in leading relationship thereto. The crop lifter has an inclined ramp operable to lift previously severed crop material away from the corresponding knife before the knife operatively severs the standing crop material to facilitate a feeding of the severed crop material into the conditioning mechanism. The top of the crop lifter is being positioned in substantially the same plane as the raised central portion of the disc cutter for properly lifting the severed crop material toward the conditioning mechanism and for protecting the hardware detachably fastening the corresponding knife to the disc cutter.
摘要:
A curved implement tongue improves the turning characteristics of the implement, such as a mower-conditioner. The tongue is bent in the horizontal plane and incorporates a generally vertical box section at the end of the tongue. The tongue supports a driveline transmitting rotational power from a prime mover to the operative components of the mower-conditioner. The driveline incorporates a clutch assembly mounted on the input shaft of a bevel gearbox. The forward end of the input shaft is formed with a conical surface that mates with a corresponding conical hub bore formed within the clutch assembly. The end of the input shaft is formed as a truncated cone to provide a gap between the end of the shaft and the bottom of the bore and assure a proper seating of the two members.
