Patent number: 11040591Abstract: A wheeled work vehicle (1) comprises a forward chassis part (4) and a rearward chassis part (5) pivotally connected about a substantially vertically extending primary pivot axis (7) for steering thereof. A pair of forward ground engaging wheels (29) are carried on a forward suspension unit (32), and a pair of rearward ground engaging wheels (30) are carried on a rearward suspension unit (33). The forward suspension unit (32) is pivotally connected to the forward chassis part (4) by a pair of main forward transverse pivot shafts (63) pivotally coupled to the forward chassis part (4) by corresponding main forward pivot mountings (65). The main forward transverse pivot shafts (63) defines a main forward transverse pivot axis (59) about which the forward suspension unit (32) is pivotal relative to the forward chassis part (4).Type: GrantFiled: December 7, 2016Date of Patent: June 22, 2021Assignee: MULTIHOG R&D LIMITEDInventors: James McAdam, Gerard McHugh, Anthony Duff, Dallan McHugh, Daniel McElchar, Samuel Hampshire

Patent number: 10953739Abstract: A work vehicle (1) comprising a forward part (3) and a rearward part (7) pivotally coupled about a main vertical pivot axis (10) for steering thereof. A power take-off shaft (29) is located adjacent a forward end (31) of the forward part (3) and is mechanically driven from a main output drive shaft (15) of an engine (14) located in the rearward part (7). A step-up gearbox (20) steps up the speed from the main output drive shaft (15) onto first and second output shafts (23, 24) for driving first and second hydraulic pumps (27, 28) which provide hydraulic supplies for motive power and for operating attachments attached to the forward end (31) of the forward part (3). A step-down gearbox (30) receives drive directly from the main output drive shaft (15) of the engine (14) and produces a stepped-down drive on an output shaft (33) of the step-down gearbox (30) with a gear ratio of 2:1.Type: GrantFiled: November 3, 2016Date of Patent: March 23, 2021Assignee: MULTIHOG R&D LIMITEDInventors: James Mcadam, Gerard Mchugh, Anthony Duff, Dallan Mchugh, Daniel Mcelchar, Samuel Hampshire

Patent number: 10939602Abstract: A work vehicle (1) comprises a coupling apparatus (18) for coupling an attachment to the forward end (8) of the work vehicle (1). The coupling apparatus (18) comprises a three point linkage mechanism having a pair of lower coupling elements (19) and an upper coupling element (25). A first carrier element (22) is pivotally coupled to a forward chassis part (14) of the work vehicle (1) by a pair of main transverse pivot shafts (35) which define a main transverse pivot axis (33). A second carrier element (23) carries the lower coupling elements (19) and is pivotally coupled to the forward chassis part (14) about the main transverse pivot axis (33) and about a main longitudinal pivot axis (45).Type: GrantFiled: December 7, 2016Date of Patent: March 9, 2021Assignee: MULTIHOG R&D LIMITEDInventors: James McAdam, Gerard McHugh, Anthony Duff, Dallan McHugh, Daniel McElchar, Samuel Hampshire
