Abstract: A telescopic boom (10) suitable for a material handling vehicle is provided. The boom comprises two telescopic sections. One end (12a) of an inner tube element (12) is telescopically slideable in one end (14a) of an outer tube element (14) so that a majority length of the inner tube element can be received therein. An intermediate element (16) is also provided, a first end (16a) of which resides within, and is slideable in, the outer tube element (14). A second end (16b) of the intermediate element is telescopically slideable in the end (12a) of the inner tube element (12) that resides inside the outer tube element. A first stop (20) serves to limit withdrawal of the first end (16a) of the intermediate element from the outer tube element (14), whilst a second stop (18) serves to limit withdrawal of the second end (16b) of the intermediate element from the inner tube element (12).

Abstract: A real-time performance evaluation system can compare machine performance to a performance standard. A Fleet Operations Subsystem (FOS) can determine a machine status such as Parked, Idle, Working, Travel or Turning. The FOS can be configured to determine machine performance by determining the amount of time spent in each status. The performance can be compared to predetermined performance standards, for example a minimum number of hours spent working, or a maximum number of hours spent idle. A performance score can be generated based on the comparison. A report of the performance evaluation can be provided. A report can be in the form of a performance marker graphic on a visual display. The performance marker can represent the performance score. The performance marker can be in the form of an alarm symbol for a poorly performing machine. The system provides an operator or manager the opportunity to improve machine performance.

Abstract: A continuous round baler system has a baler and an accumulating system. The accumulating system includes a conveyor configured to convey crop material extending from a pickup mechanism to a bale formation chamber in the baler. A screed is positioned adjacent the end of the conveyor and is configured to be movable by a lifting mechanism between a raised position and a lowered position relative to the first conveyor. In the raised position, a gap is formed between the screed and the first conveyor so that crop material passes into the bale formation chamber. In the lowered position, the gap is closed thereby preventing the crop material from passing to the baler causing the crop material to remain on the conveyor.

Abstract: Dry yield for baled forage crop materials may be obtained for specific cut locations in the field by allocating the overall average baled dry yield for the entire field to the specific cut locations in accordance with the cut yield at such locations. Information obtained from a position sensor and one or more crop volume sensors on the windrower or mower is later combined with information obtained from a weight sensor on the baler to arrive at a specific location dry yield report for the baled product.
