Filed:

Feb 14, 2001

Appl. No.:

09/783655

Inventors:

Kevin Laverne Ehrecke - Davenport IA

Assignee:

Deere Company - Moline IL

International Classification:

A01D 7528

US Classification:

56 102R, 56DIG 15, 460 1

Abstract:

The combine of the present invention is provided with an internal combustion engine. An electronic engine controller is used to monitor and control the operation of the engine. The electronic engine controller stores at least two power curves for controlling the engine. The first power curve has a higher horsepower output than the second power curve. A harvesting assembly detector signals the electronic engine controller with a corn head signal if a corn head is mounted to the combine, or a grain platform signal if a grain platform is mounted to the combine. If a corn head is mounted to the combine the electronic engine controller derates the engine and works on the second power curve. If the electronic engine controller receives a grain platform signal, the electronic engine controller works on the higher horsepower first power curve.

US Classification:

460 68

Abstract:

A rotor, in an agricultural harvester crop processing unit, comprising a drum to which crop processing elements for an infeed section and a threshing section are affixed. The drum comprises a rearward cylindrical portion and a forwardly extending frusto-conical portion. The frusto-conical portion is divided into an aft-region adjacent to the rearward cylindrical portion of the drum, and a fore-region. The infeed section has at least one infeed element located on the fore-region of the frusto-conical portion of the drum. The crop processing section has at least one crop processing element located on the aft-region of the frusto-conical portion of the drum.

International Classification:

B60P 300
B60P 708
B61D 316
B61D 4500

US Classification:

410 44

Abstract:

A transporter or trailer for endwise transport of combine headers and the like, consists of a standard four-wheel wagon running gear carrying an elongated generally rectangular frame providing support surfaces compatible with a variety of sizes and types of header. A pair of longitudinally spaced fixed pockets at the left-hand side of the adapter frame receives heel portions adjacent the rear of headers of the corn head or row-crop head type while a somewhat elevated, swingably adjusted, rail may be set to an appropriate contact and support forward portions of a particular header. In alternative embodiments, an auxiliary laterally adjustable rail may support a second front portion of a header, or additional support "cradles" may be attached along the left-hand side of the frame to accommodate headers with elongated transverse beam members such as grain platforms.

International Classification:

A01D 6700

US Classification:

56 144

Abstract:

In a flexible floating cutterbar cutting platform for a combine harvester, compact spring elements connected to cutterbar suspension linkage subassemblies are remotely controlled for adjustment of cutterbar counterbalance force so that pressure between the ground and the cutterbar skid plates may be adjusted, on-the-go, to suit varying harvesting conditions. Pinned pivotable connection of the cutterbar suspension linkage subassemblies to the rigid portion of the platform facilitate assembly and offer an improved method of adjustment of cutterbar attitude relative to the ground (tilt) when in working position.

Abstract:

One or more techniques and/or systems are disclosed for a center frame positioning method for an agricultural sprayer. The method comprises activating a center frame positioning system and collecting and processing position data related to a position of a suspended center frame in the center frame positioning system. The method further comprises evaluating the position data to determine whether any adjustment to the position of the suspended center frame is needed and controlling actuator force in at least one actuator to adjust the position of the suspended center frame based on the evaluating the position data.
