Patent number: 8585534Abstract: A control system for use in a vehicle having left and right clutch assemblies, each including a brake mechanism and a drive mechanism. The control system includes a steering switch having multiple steering positions to actuate the corresponding brake mechanism and opposite drive mechanism and a neutral position to actuate both drive mechanisms. The system may also include an operator switch having a first position to actuate the brake mechanisms and disable the steering switch, and a second position that enables control of the brake clutch assemblies by the steering switch. The system may include a brake switch having a brake position that actuates both brake mechanisms and disables the operator and steering switches, and a drive position that passes control of both clutch assemblies to the operator switch.Type: GrantFiled: July 19, 2012Date of Patent: November 19, 2013Assignee: Hydro-Gear Limited PartnershipInventors: Raymond Hauser, Christopher K. Wyatt, Lonnie E. Holder, Scott W. Keller

Patent number: 8575800Abstract: An electric motor includes an upper housing, a lower housing including a flange for mounting the upper housing thereon and a cone-shaped portion extending away from the flange and the upper housing. The electric motor further includes a stator assembly formed of a first core having a first height and fitted into the upper housing, a rotor assembly rigidly joined to a shaft to rotate therewith within the stator assembly and formed of a second core having a second height, and a hub connected to a lower end of the shaft to rotate therewith in relation to the cone-shaped portion. The hub is configured to secure an operable implement to the electric motor. The second height is greater than the first height.Type: GrantFiled: July 20, 2012Date of Patent: November 5, 2013Assignee: Hydro-Gear Limited PartnershipInventors: Ivan E. Fox, Christopher K.
