Patent number: 10071610Abstract: A method for providing improved ride control for a work vehicle when transporting a drawn implement may include monitoring a load applied through a drawbar-related component(s) of the work vehicle while the drawn implement is being transported, wherein the drawn implement is located at a transport position relative to a driving surface of the work vehicle such that a ground engaging tool of the drawn implement is located above the driving surface. The method may also include detecting a variation in the monitored load over time, comparing the detected load variation in the monitored load to a predetermined load variance threshold and controlling an operation of at least one of an implement suspension system of the drawn implement or a vehicle suspension system of the work vehicle so as to reduce the detected load variation in the monitored load when the load variation exceeds the predetermined load variance threshold.Type: GrantFiled: October 30, 2015Date of Patent: September 11, 2018Assignee: CNH Industrial America LLCInventor: Thomas B. Tuttle

Patent number: 9033094Abstract: An engine mount assembly is provided for mounting an engine to a vehicle frame. The engine mount assembly includes an elastomeric material snubber element having a generally elongated configuration with axial end faces and a coaxial bolt passage defined therethrough. A tubular sleeve has an inner shape sized for sliding receipt of the snubber element therein. The tubular sleeve has a longitudinal cross-sectional profile such that a bottom longitudinal cross-sectional portion of the tubular sleeve extends axially beyond the end faces of the snubber element and defines an enlarged attachment footprint for the tubular sleeve to a vehicle frame flange.Type: GrantFiled: July 29, 2013Date of Patent: May 19, 2015Assignee: CNH Industrial America LLCInventors: Dayalbhai R. Patel, Thomas B. Tuttle, Suresh P. Pai

Patent number: 8991274Abstract: A mounting surface of an agricultural work vehicle power takeoff system. In one example, an agricultural vehicle includes a power takeoff (PTO) device. The PTO device includes a drive shaft and a mounting surface. Furthermore, the mounting surface includes a plurality of threaded apertures for coupling an auxiliary system to the PTO device, and a pilot configured to engage with a complimentary pilot of the auxiliary system to facilitate alignment of the PTO device with the auxiliary system. The mounting surface and the auxiliary system have the same mounting configuration.Type: GrantFiled: June 26, 2013Date of Patent: March 31, 2015Assignee: CNH Industrial America LLCInventor: Thomas B. Tuttle

Patent number: 8939241Abstract: A drive system for an agricultural work vehicle. The drive system includes a front power takeoff device configured to extend from a front portion of the agricultural work vehicle and to be driven by an engine. The drive system also includes a first gearbox and a second gearbox positioned between the engine and the front power takeoff device. The first gearbox is configured to be driven by the engine and to provide power to drive the second gearbox. The second gearbox is configured to be driven by the first gearbox and to provide power to drive the front power takeoff device. The first gearbox and the second gearbox each provide a vertical shift between a respective driven input and a respective driving output.Type: GrantFiled: April 3, 2012Date of Patent: January 27, 2015Assignee: CNH Industrial America LLCInventors: Thomas B. Tuttle, Edmund R. Henkel, Benjamin L. McCash

Patent number: 6234508Abstract: A load sensor is provided on a tractor to sense a load in the upper link of a three point hitch. The load sensor is fixed to the upper link, rather than the tractor to move with the upper link rather than the tractor. This arrangement permits the load sensor to always indicate the longitudinal load placed on the upper link.Type: GrantFiled: September 3, 1999Date of Patent: May 22, 2001Assignee: Case CorporationInventors: Thomas B. Tuttle, William L. Schubert, Michael Stelzle
