Assignee:
Deere & Company - Moline IL
International Classification:
A01D 34/53
US Classification:
56249
Abstract:
A system adjusts the height-of-cut of a cutting reel unit. The system includes a cutting reel; a first frame supported on at least one support element that is supported on, and is movable along, the ground; and a second frame supporting the cutting reel. The system further includes an actuator that has a first portion connected to the first frame and a second portion connected to the second frame, wherein a distance between the first and second portions is adjustable. The actuator includes a motive mechanism that is activated to adjust the distance. The system can include at least one strut pivotally connected to the first frame and pivotally connected to the second frame on a second side of the second frame opposite to the first side. The strut extends between the first frame and the second frame. The strut defines the rotation of the second frame with respect to the first frame as the relative elevation of the second frame is adjusted with respect to the first frame.

Assignee:
Deere & Company - Moline IL
International Classification:
A01D 34/42
US Classification:
56249
Abstract:
A user interface and control system for adjusting the reel of a cutting reel unit includes a frame supported by at least one support element that is supported on, and is movable along, the ground. The system also includes a cutting reel, a bedknife, first and second actuators, a controller, and an operator input station, all carried on the frame. The reel and bedknife define a cutting line therebetween. The first actuator is adjustable to set a clearance between the reel and the bedknife. The second actuator is operatively connected between the frame and the bedknife to adjust the elevation of the cutting line to set a height-of-cut of the cutting reel. The controller is signal-connected to the first and second actuators, to adjust the actuators. The operator input station is signal-connected to the controller, the operator input station including a keypad portion and a display portion, wherein the clearance and the height-of-cut are indicated on the display portion and the clearance and the height-of-cut can be selectively changed via the controller by operator input to the keypad portion.

Assignee:
Deere & Company - Moline IL
International Classification:
A01D 34/53
US Classification:
56249, 56 104
Abstract:
A control system for a cutting reel unit includes a height-of-cut adjusting system and a reel-to-bedknife clearance adjusting system. The height-of-cut adjusting system includes a first frame; a second frame; a cutting reel supported by the second frame; a bedknife arranged adjacent to the cutting reel and supported by the second frame; at least one support element arranged to translate along the ground and arranged to support the first frame; and at least one first actuator connected between the first frame and the second frame and arranged to adjust the relative elevation of the second frame with respect to the first frame. The reel-to-bedknife clearance adjusting system includes at least one second actuator operatively connected between the reel and the second frame and a sound detector.
Method And Apparatus For Setting And Maintaining Reel-To-Bedknife Clearance
US Patent:

Assignee:
Deere & Company - Moline IL
International Classification:
A01D 34/53
US Classification:
56249, 56 102 E, 241 37
Abstract:
A control system for a cutting reel unit includes a reel-to-bedknife clearance adjusting system. The reel-to-bedknife clearance adjusting system includes at least one actuator operatively connected between the reel and the bedknife, and a sound detector. A controller is signal-connected to the actuator and the sound detector and coordinates the reel-to-bedknife clearance adjustment. During adjustment, reel-to-bedknife clearance is reduced by the actuator until a contact sound between the reel blades and the bedknife is detected and signaled to the controller, which then reverses the actuator and increases the clearance by a pre-selected precise amount.

Method And Apparatus For Controlling Tracked Vehicles
US Patent:
7784568, Aug 31, 2010
Filed:
Sep 18, 2008
Appl. No.:
12/233284
Inventors:
John Petersen - Providence UT, US
Eric Poulson - Paradise UT, US
Eric Poulson - Paradise UT, US
Assignee:
Freeport-McMoRan Copper & Gold Inc. - Phoenix AZ
International Classification:
B62D 11/00
US Classification:
180 67, 701 83
Abstract:
Apparatus for controlling a track on a tracked vehicle may comprise a drive system, a clutch, a brake, and a track control system to operate the clutch and the brake. A control signal generator operatively associated with the track control system produces control signals that vary at a first rate to cause the track control system to transition the clutch from an engaged state to a disengaged state and produces control signals that vary at a second rate to cause the track control system to transition the brake from an initial application state to a full application state, the second rate being less than the first rate.
