20100204891 | ACCELERATION CONTROL FOR VEHICLES HAVING A LOADER ARM - A control system for a vehicle having a loader arm, such as a skid steer loader, telescopic handler, wheel loader, backhoe loader or forklift, reads a load height sensor, a load weight sensor; dynamically calculates the static center of gravity of the combined vehicle and load; calculates the acceleration necessary to cause the dynamic center of gravity of the combined vehicle and load to extend exterior of the vehicle's stability polygon; and limits the acceleration of the vehicle to less than the acceleration necessary to cause the dynamic center of gravity of the combined vehicle and load to extend exterior of the vehicle's stability polygon. | 08-12-2010 |
20110088961 | ELECTRONIC THROTTLE ON CONTROL HANDLE - A steering and engine speed control mechanism for operating a vehicle. The control mechanism has a control handle mounted on the vehicle. The control handle is configured to deflect about an axis by movement of an operator's hand. A steering direction of the vehicle is related to a deflection angle of the control handle about the axis. An actuating element for changing the speed of the engine of the vehicle is attached to the control handle and is conveniently movable by an operator's digit to a plurality of positions to effect the desired speed of the engine. | 04-21-2011 |
20120315964 | AIR DIVERTER FOR COMBINE SHOE - A cleaning system in a combine harvester includes a fan producing an airstream, an oscillating upper chaffer that separates grain and smaller residue from larger non-grain particles while the airstream entrains light non-grain particles and carries them out the rear of the machine. An oscillating lower sieve receives the grain and smaller residue passing through the upper chaffer and allows grain to pass through openings while residue unable to penetrate the lower sieve travels off the end of the lower sieve and the airstream entrains light non-grain particles and carries them out of the machine. An airstream diverter located between the upper chaffer and the lower sieve redirects a portion of the airstream through lower air-flow areas of the upper chaffer. The diverter is horn-shaped with a narrow leading edge and a wider trailing edge with a concave air-directing surface between the leading and trailing edges. | 12-13-2012 |
20130137492 | THROUGHPUT CONTROL ADJUSTABLE VANES ON AGRICULTURAL COMBINE HARVESTER - A threshing mechanism for a combine harvester has a cylindrical rotor for moving crop materials and a plurality of separator tines secured thereon for threshing crop material. A rotor chamber has a top casing forming an upper portion defining a volume of space between the rotor and the top casing. A plurality of crop transport vanes extend away from an inward surface of the top casing to direct the crop material generally helically along the chamber. The vanes have a rotor-facing edge at an outer end away from the inward surface of the top casing. The vanes are positionable between a base position and at least one extended position with respect to the rotor, wherein in the base position, the rotor-facing edge is positioned a greater distance from the rotor than when in the at least one extended position. | 05-30-2013 |
20130157731 | Method for Measuring Air Efficiency and Efficacy in a Combine Harvester - The airflow through a harvesting machine is adjusted by calculating a G-factor at a first point on an upper chaffer to determine if it is greater than 1+n, where n represents a desired factor. A blower is adjusted to reduce an airstream if the G-factor is greater than 1+n. A MOG factor is calculated if the G-factor is less than 1+n. The blower is adjusted to increase the airstream if the MOG-factor is less than 1+x, where x represents a desired factor. A MOG-factor is calculated at a second point if the MOG-factor at said the point is greater than 1+x and the blower is adjusted to reduce the airstream if the MOG-factor at the second point is greater than 1+y, where y represents a desired factor or adjusted to increase the airstream if the MOG-factor at the second point is less than 1+y. | 06-20-2013 |

20150132093 | GRAIN UNLOADER FOR COMBINE HARVESTER - A combine has a grain bin with a sump and an unloading system for unloading grain out of the bin. The unloading system has a pivoting unloading tube assembly movable between a storage position and an unloading position. The unloading tube assembly has an inner riser section and a variable-length outer transport section. When the unloading tube assembly is in the storage position, at least a portion of the inner riser section nests underneath a rear floor portion of the grain bin. The variable-length transport section has a proximal chute nested with a distal chute that can be moved relative the proximal chute. A nested conveyor assembly transports grain through the variable-length section. The nested conveyor assembly includes an endless conveyor and pulleys configured to form an upper grain transporting reach inside of the chutes and a return reach outside of the chutes. | 05-14-2015 |
