Patent number: 8511049Abstract: A suspension system for agricultural implements having at least one floating head using a four-bar linkage and permitting the floating head to accommodate variations in ground surface elevation in a lateral or transverse direction. By permitting the floating head to float, a more consistent cutting height is realized when ground surface elevation varies in a transverse direction. A main frame is provided to which the ground engaging wheels are attached. A sub-frame is connected to the main frame via the four-bar linkage. The sub-frame is pivotally attached to the arms of the four-bar linkage by spherical bearings.Type: GrantFiled: September 5, 2012Date of Patent: August 20, 2013Assignee: Vermeer Manufacturing Co.Inventors: Kent L. Thompson, Shane A. Bollinger, Rustin V. Bentzinger

Patent number: 7658056Abstract: A drive system for agricultural implements having at least one floating head and a tongue that may be disposed at various angles relative to a longitudinal angle of the implement. Two swivel gearbox assemblies are used, each comprising a first 90° gearbox rigidly attached to the implement and a second 90° gearbox that is permitted to rotate about an axis passing through one of its shafts and one of the first 90° gearbox's shaft. Because the tongue angle is variable, the drive shafts for driving the implement must take on a plurality of angles. The swiveling gearbox assemblies allow variable angles at the tongue and at the header.Type: GrantFiled: October 30, 2007Date of Patent: February 9, 2010Assignee: Vermeer Manufacturing Co.Inventors: Kent L.

Patent number: 7654479Abstract: An improved brush cutter having an upper feed control member with stop, forward, neutral, and reverse positions also has a lower feed stop member with selectable sensitivity. Another aspect of the invention is to predict the feed roller shutoff point according to the rate of engine deceleration. According to another aspect, when the feed rollers stop feeding material into the cutters, to overcome drag on the cutters, a controller stops the feed rollers and then reverses them for a short time, and then reverses the rollers again if the problem is still present. To prevent jamming, a pressure switch senses when oil in a hydraulic motor system for rotating the feed rollers is too high and the controller momentarily reverses the feed rollers and then causes them to go forward, a cycle which can occur several times until the feed rollers are no longer stalled.Type: GrantFiled: February 17, 2009Date of Patent: February 2, 2010Assignee: Vermeer Manufacturing Co.Inventors: Mark R Stelter, James L. O'Halloran, Dennis K. Gabler, Jeffrey D. Kernwein, Ivan R. Brand, Brian M. Johnson

Patent number: 7562837Abstract: A brush chipper with feed rollers and a winch has an interlock control with feed roller disabled position and a feed roller enabled position, spring loaded to the feed roller disabled position to encourage or require the use of the winch line to move it into a feed roller enable position. A winch control is provided that selects between a winch freewheel condition and winch drive condition. A connection is provided between the interlock control and winch control such that the interlock control automatically moves to the feed roller disabled position whenever the winch control is moved to the freewheel position.Type: GrantFiled: May 31, 2007Date of Patent: July 21, 2009Assignee: Vermeer Manufacturing Co.Inventors: Ivan Brand, John T.

Patent number: 7546964Abstract: An improved feed roller assembly wherein the feed roller provides a force perpendicular to the feed direction of the brush material. In a first embodiment, cleats that are not parallel to an axis of rotation of the feed roller are affixed to a periphery of the feed roller. When the feed roller is oriented with its axis of rotation in a substantially vertical position, each cleat is arranged with its upper end ahead of its lower end, in a direction of rotation. This configuration provides a downward force on the logs or brush being fed into the chipper, thereby reducing the occurrence of bucking. In an additional embodiment, the axes of rotation of the feed rollers lean toward the outfeed end of the brush chipper.Type: GrantFiled: May 4, 2007Date of Patent: June 16, 2009Assignee: Vermeer Manufacturing Co.Inventor: John T.

Patent number: 7543767Abstract: A mechanical control mechanism for the feed of a brush chipper is disclosed. The feed control bar has four positions: (1) forward or feed, (2) neutral, (3) reverse, and (4) stop. The hydraulic control valve has the three usual positions: (1) forward or feed, (2) neutral, (3) reverse. A function of the feed control bar is to provide the three function of the hydraulic control valve, plus the fourth in a fashion amenable to emergency situations. To these ends, the control bar has an extreme rearward position wherein the feed mechanism is stopped. The only permissible change to the stopped condition of the feed mechanism is to reverse the feed. Until a reset lever is manipulated, the hydraulic control valve cannot be put into a forward feed position.Type: GrantFiled: June 30, 2005Date of Patent: June 9, 2009Assignee: Vermeer Manufacturing Co.Inventors: John T.

Patent number: 7181900Abstract: A baler having an inlet area for receiving netwrap wherein it is a short distance between the drum roller and the closest belt roller. The netwrap guide at bottom of baler includes a feed pan having flexible net guides that are narrower than the bale forming belts. This netwrap guide has supporting cross members underneath it but there are no cross members in close vicinity to the lower belt roller to keep excess crop from accumulating there. There is also a netwrap guide at front of the baler for feeding netwrap material into contact with the periphery of a formed bale, including a guide positioned generally above the pickup for directing crop material previously inserted into the bale formation chamber and the netwrap material away from the pickup. The baler also has a novel netwrap feeding and cutting mechanism.Type: GrantFiled: November 21, 2003Date of Patent: February 27, 2007Assignee: Vermeer Manufacturing Co.Inventors: William A.

Patent number: 7086214Abstract: A suspension system for a tractor-drawn mower used for crops for agricultural purposes is made up of parallel links, connected at a first end to a frame and to a mowing unit at a second end. A torsion spring assembly, similar to that used for torsion axles, is used to bear a portion of the weight of the mowing unit when the mowing unit is in a lower, mowing position. All torsional stress is removed from the torsion spring when the mowing unit is in a transport position. During mowing, the weight of the mowing unit is divided up between the torsion spring and the surface of the ground. The ratio of the weight supported by the ground to that supported by the torsion spring is adjustable by an operator.Type: GrantFiled: April 27, 2005Date of Patent: August 8, 2006Assignee: Vermeer Manufacturing Co.Inventors: Kent L.

Patent number: 5822967Abstract: An apparatus for forming and wrapping round bales includes a baler, arm structure, a cradle, and moving structure. The baler is for taking in a crop material, forming the crop material into a bale, and ejecting the bale. The arm structure is connected to the baler. The cradle is pivotably supported by the arm structure and is for holding the ejected bale. The cradle includes rotating structure for rotating the bale about a central axis of the bale. Moving structure is for providing relative movement between the baler and the cradle. Wrapping structure is supported by the baler and is adapted for holding wrapping material.
