The simultaneous, real time graphical information is shared between two or more intelligent work stations linked together in conversation via a network. Transmission of the essence of a graphical image is accomplished by fixed and variable length portions. The fixed portion describes the type of command and the size or length of the variable length portion. The variable length portion describes the detailed information need to properly process. Thus, the complete length of data is known a priori. While a network is constipated or congested and a drawing operation is being performed by a user, the communication endpoints are configured as non-blocking, commands are stored in a FIFO (first-in, first-out) queue, and the operating system reports how much of the drawing operation was transferred. After the network becomes unconstipated, writing of any partially written command or stored commands in the queue are completed. The graphical image may be displayed in a window or canvas designated for drawing. By transmitting the parameters defining the object and its commands, the speed of the transmission is increased over pixel-by-pixel transmission.

A ball joint assembly for a draft link of a three-point hitch on the tractor. The ball can be assembled through a slot in a side of the link and rotated in a spherical socket where it is retained by a retaining element.

A top mounted lift hydraulic ram on a tractor for a three-point hitch mounted on a removable subassembly to facilitate assembly and convenience in servicing.

A lower draft arm extension link stop in a tubular member of a lower draft arm of a three-point hitch for engaging the extension link in its extended position. The extension link is provided with a relief portion which clears the stop when the link is angular inclined so that it can be withdrawn from the tubular member. The tubular member includes a latch, axially aligned with the stop, for holding the link in its contracted position.

Draft arm extension stop

An adjustable lift link on a three-point hitch having a self-locking handle and retainer for selectively adjusting and holding the adjustment of the lift link. A stop on the link selectively provides the float or fixed length positions of the link of the three-point hitch.

A draft load sensing mechanism for a vehicle having a torsion bar carrying the draft load from the lower draft arms which produce a torsion load on the bar. A preload adjusting screw applies a preload torque to the torsion bar and a load limit adjusting screw limits the maximum torque load that can be applied to the torsion bar responsive to the draft load on the vehicle.

Torsion bar draft load limit and preload adjuster

A hydraulic filter mounting arrangement with a sealing means on the filter element and a cover operated valve for closing off the hydraulic system from the chamber receiving the filter element when replacing the filter.

Hydraulic filter and valve arrangement

A sway limiting device for a three-point hitch on a tractor having reversible sway limiting blocks. The sway limiting blocks in one position permit sway of the hitch and implement under field operating conditions and in another position eliminate sway of the hitch throughout the fulllift range of the hitch by interchanging the right and left-hand sway blocks and using the reverse side of the sway blocks.

Reversible sway limiting blocks for a tractor hitch

A subassembly for use in a position in draft control linkage for operation by cables connected to position and draft control levers. The subassembly includes a mechanical hydraulic valve operating linkage and a position and draft load and sensing linkage sensing position draft and load of the hitch on a tractor. The subassembly is removably mounted as a unit on the vehicle chassis and can be adjusted prior to positioning on the tractor.
