Abstract: An off-road vehicle includes an engine compartment with an engine disposed therein and a cooling assembly which includes a source of liquid and a cooling location disposed external to the engine compartment for cooling the liquid. One or more heat exchangers is disposed at the cooling location for cooling the liquid, which may include engine coolant, hydraulic fluid or air conditioning coolant. Preferably, the cooling assembly includes a fan which is elevated to minimize the intake of dust and other debris created during operation of the vehicle.

Abstract: A stump cutting apparatus for connection to an excavator or other prime mover for conveyance in any ground breaking or farm industry. The stump cutter apparatus comprises a chassis for supporting for supporting stump cutter, a cutting assembly, an engine for providing power to the cutting assembly, an attachment member for releasably attaching the stump cutter to an excavator or other prime movers. The chassis may include one or more support legs or in the alternative one or more wheels to allow for support and easy movement of the apparatus. The cutting assembly comprises of support legs which comprises one or more spikes extending downward to be able to be received by the surface to enable the apparatus to be secure during stump cutting operation. The stump cutting apparatus also has several hydraulic cylinders for supporting the stump cutter by retracting and extending the members of the apparatus and enable to cutter wheel to move to meet the objective of user for cutting stumps and roots.

Abstract: The present invention is directed to an operator's station from which a user may control the operation of a stump cutter or machines wherein the operator's station comprises: a control panel including at least one machine control switch or actuator; a controller for receiving commands from the control panel and in turn causing a stump cutter or machine to implement the commands; and, a wireless coupling of the control panel to the controller which is only operative in a pre-determined zone or area.

Abstract: The present invention is directed to a protective operator's station from which a machine operator may safely and effectively remotely control the various operations of a machine that may create flying debris. The invention includes a control panel mounted to an adjustable base, such as a tripod with extensible legs. The invention also includes one or more shields to protect the machine operator from flying debris. A substantially transparent shield is provided to protect the upper body and head of a machine operator without substantially impairing the operator's vision. A flexible lower shield or skirt may be provided to protect the lower body of the operator. In an alternative embodiment, the control panel, including one or more shields, may be secured to the body of the machine operator using a harness. The invention also relates to an improved remotely controlled stump cutter having a protective operator's station.

Abstract: A cutting tooth for use in a stump cutting apparatus wherein the cutting tooth comprises a mounting base and a head portion which are integral with one another and are made of a one-piece metallic forging. The forging is preferably made from AMS 4140 steel and the cutting tooth further comprises a cutting tip, preferably of tungsten carbide, which is fixedly attached to the head portion of the tooth. The disclosed preferred embodiments include those in which the head portion is disposed in a substantially straight line relationship with the mounting base and those in which the head portion is curved relative to the mounting base.

Abstract: The present invention relates to an impact driven tree transplanting device or tree spade wherein each of the excavation blades is connected to an impact device for generating and/or transferring a series of repetitive impacts or blows to the excavation blades so that the blades more easily enter the earth surrounding the base of a tree or another location. Specifically, the impact devices cause the blades to move more easily downward into the earth by cutting through roots and by breaking and/or displacing rocks and other obstructions. The present invention also includes the ability to lift a tree from the ground and transport the same to another location. Also, the present invention may be used in a non-impact driven mode where relatively loose soil or otherwise easily excavated soil conditions prevail.

Abstract: A cutting tooth for use in a stump cutting apparatus wherein the cutting tooth comprises a mounting base and a head portion which are integral with one another and are made of a one-piece metallic forging. The forging is preferably made from AMS 4140 steel and the cutting tooth further comprises a cutting tip, preferably of tungsten carbide, which is fixedly attached to the head portion of the moth. The disclosed preferred embodiments include those in which the head portion is disposed in a substantially straight line relationship with the mounting base and those in which the head portion is curved relative to the mounting base.

Abstract: A method and system for automated nucleic acid sequence determination of a polynucleotide, wherein a nucleic acid sequencing ladder comprises signals corresponding to oligonucleotides formed from the polynucleotide, comprising the step of correlating, particularly in a trained neural network or a scatter plot, an intensity variable for each signal in the nucleic acid sequencing ladder with an informative variable for that signal, wherein the informative variable comprises information from at least two adjacent signals in the nucleic acid sequencing ladder, such that each signal in the nucleic acid sequencing ladder identified so as to determine the nucleic acid sequence corresponding to the polynucleotide.

Abstract: An improved stump cutting apparatus and particularly a two-wheel trailer type of stump cutting apparatus employing a hydraulic motor, to, through a drive belt connection, drive a cutting wheel, the hydraulic motor being powered by a hydraulic pump directly mounted on a diesel engine strategically located on a cutting wheel boom, giving the unique benefit of thereby increasing cutting stability due to the presence of the substantial mass of the diesel engine and its centrally-balanced orientation.The cutter boom sweeps side-to-side relative to the hinge head to which it is attached, and the same hinge head provides up and down motion of the cutter boom by owning a pivot located at its bottom end, whose pin unites the same member with the apparatus frame.The present invention operates in combination with a chip-retaining deck that remains elevationally stationary relative to its transporting wheels throughout the entire stump cutting operation.

Abstract: This invention relates to a motor driven tug vehicle which utilizes essentially three wheels, two parallel independently controlled driven wheels and a rearward balancing, fully pivotal dolly wheel, and wherein the vehicle operator is located essentially between and directly over the driven wheels so as to be immediately adjacent the connecting hitch, and having it in the visual line of sight, whereby precise control of the independent drive wheels in a forward and reverse direction can allow very controlled and precise maneuvering of the vehicle and the hitch as selectively desired by the vehicle operator.
