Patent number: 6543861Abstract: A tensioning device is provided for maintaining the tension on a continuous flexible track of a track apparatus. The track apparatus includes an idler wheel which engages the flexible track and which is movable between a first non-deflected position and a second deflected position. A dampening mechanism extends between an idler axle which supports the idler wheel and the frame of the track apparatus in order to exert a force on the idler axle to urge the idler wheel towards the non-deflected position. The dampening mechanism progressively increases the force on the idler axle as the idler wheel moves towards the deflected position.Type: GrantFiled: July 28, 2000Date of Patent: April 8, 2003Assignee: AgTracks, Inc.Inventors: Glenn W. Kahle, David L. Juncker, Jamsheed Reshad

Patent number: 6543862Abstract: A drive wheel is provided for mounting on a rotatable axle of a vehicle for driving a continuous flexible track. The flexible track includes an inner surface having a plurality of lugs and terminating at terminal surfaces. The drive wheel includes a central hub mountable on the axle of the vehicle for rotational movement therewith. First and second side-surfaces extend radially from the central hub and an outer rim interconnects the radial outer edges of the side-surfaces. It is intended that the terminal surfaces of the lugs engage the outer rim of the drive wheel such that the lugs are supported when the flexible track is driven by the drive wheel.Type: GrantFiled: July 28, 2000Date of Patent: April 8, 2003Assignee: AgTracks, Inc.Inventors: Glenn W.

Patent number: 6536854Abstract: A drive wheel engaged with flexible track of track apparatus mountable on a vehicle axle, the drive wheel including a peripheral portion which, between radially-extending drive members, has outwardly-facing lug-engagement surfaces in position for engagement with the distal surfaces of the track lugs, to extend the useful life of flexible track. Preferred embodiments have spaces facilitating removal of debris. Certain preferred lug-engaging surfaces are provided by peripherally-spaced cross-members. The drive wheel is preferably free of side structure, allowing track lugs to adjust precise positions of engagement with lug-engagement surfaces.Type: GrantFiled: March 19, 2002Date of Patent: March 25, 2003Assignee: AgTracks, Inc.Inventors: David L. Juncker, Glenn W. Kahle, Jamsheed Reshad

Patent number: 6074024Abstract: A guide wheel for a track apparatus is provided. The guide wheel includes a central hub rotatably mounted to a frame of a track apparatus. A first guide wall extends radially from the central hub and terminates at an outer edge. A second guide wall also extends radially from the central hub and terminates at an outer edge. The first and second guide walls define a circumferentially extending channel in the guide wheel. The channel in the guide wheel sequentially receives a plurality of lugs extending from the inner surface of a flexible track of the track apparatus so as to prevent lateral movement of the track.Type: GrantFiled: July 10, 1998Date of Patent: June 13, 2000Assignee: AgTracks, Inc.Inventor: Kenneth J. Juncker

Patent number: 6074025Abstract: A track apparatus having a frame is provided. The track apparatus is mountable on a rotatable axle of a vehicle and includes a continuous flexible track and a drive wheel mountable to the rotatable axle of the vehicle for rotational movement therewith. The drive wheel drives the flexible track in response to rotation of the axle of the vehicle. The leading and trailing pairs of idler wheels and the pairs of bogie wheels of the track apparatus are mounted on stub axles so as to allow the drive wheel to pass therebetween. This, in turn, allows for the drive wheel to have an increased diameter.Type: GrantFiled: July 10, 1998Date of Patent: June 13, 2000Assignee: AgTracks, Inc.Inventors: Kenneth J. Juncker, Gary L. Kelderman, Doug Witt

Patent number: 6068353Abstract: A track apparatus is provided for mounting on a rotatable axle of a vehicle. The track apparatus includes a flexible track having an upper length and a ground-engaging lower length. A drive wheel is mountable to the rotatable axle so as to drive the flexible track in response to rotation of the axle. Leading and trailing idler assemblies are attached to the frame. Each idler assembly includes a non-pneumatic idler wheel having a plurality of voids therein. In addition, a bogie assembly is also supported by the frame. The bogie assembly includes a non-pneumatic bogie wheel having a plurality of voids therein. The idler wheels and the bogie wheels have increased dimensional reliability and provide shock absorption and self-cleaning features to the track apparatus.Type: GrantFiled: July 10, 1998Date of Patent: May 30, 2000Assignee: AgTracks, Inc.Inventors: Kenneth J. Juncker, Gary L. Kelderman, Glenn W. Kahle

Patent number: 6062661Abstract: A drive wheel mounted on a rotatable axle of a vehicle is provided for driving a continuous flexible track. The drive wheel includes a central hub mountable on the axle for rotational movement therewith. First and second rim walls extend radially from the central hub and define a circumferentially extending void in the drive wheel. A plurality of circumferentially spaced rollers are rotatably supported in the void for engaging a portion of the track.Type: GrantFiled: July 10, 1998Date of Patent: May 16, 2000Assignee: AgTracks, Inc.Inventors: Kenneth J. Juncker, Doug Witt, Glenn W. Kahle

Patent number: 5983755Abstract: An apparatus for sharpening a chain saw includes a frame, a file guide carriage having at least one guide bore capable of receiving a file therethrough, and a guide bar attached to the frame. The file guide carriage is mounted with respect to the frame so as to allow for sliding movement along an axis and an elongate opening in the carriage is coincident with the axis. The improvement includes at least one easy-to-remove adjustment screw that has spaced-apart inward and outward bearing surfaces threaded into the elongate opening. A bearing member extends from the guide bar and is interposed between the bearing surfaces. This bearing member includes a first aperture aligned with the axis and having a first diameter that allows for the receiving of the adjustment screw, and a second aperture overlapping the first aperture and having a second diameter greater than the first diameter.Type: GrantFiled: May 15, 1998Date of Patent: November 16, 1999Assignee: AgTracks, Inc.Inventors: Clarence A. Juncker, David L. Juncker
