20080245045 | Mower quick release and attachment apparatus for mowing deck - An underbelly mower has a cutting deck suspended beneath a frame by a height adjustment mechanism. The deck is adjusted between different cutting heights by extendable mechanical advantage device such as an electric screw and hydraulic ram operating in cooperation with the height adjustment mechanism. The mechanical advantage device also operably moves the deck between a cutting configuration and a maintenance configuration. A deck quick release and attachment mechanism, including hook members, operably allows a user to quickly and easily disconnect and reconnect a rear of deck to the frame when moving between cutting and maintenance configurations. | 10-09-2008 |
20090031688 | MOWER DECK ENHANCEMENT - A multiblade lawn mower has a mower deck with a downwardly directed interior opening. At least two rotary blades are disposed within the opening. A generally circular wraparound baffle is adapted to surround each rotary blade. The wraparound baffle has a throat area opening generally towards one of the walls at an acute angle and/or an opening in the mower deck. The wraparound baffle also has a sloped wall portion adapted to decrease in height gradually from the height of the wraparound baffle to an edge terminating in the throat area. A collar is attached to the top wall and extends downward to a position adjacent the rotary blade. The collar surrounds a spindle attached to the rotary blade to prevent grass buildup created by movement of the rotary blades in a vortex area proximate the spindle. | 02-05-2009 |

20090001805 | HYDRAULIC BY-WIRE BRAKE SYSTEM - A hydraulic circuit is provided for a by-wire brake system. There is a need for such a circuit which permits independent left and right brake operation and which has redundancy. The circuit includes left and right brake control valves, a left brake line communicated with a left brake, a right brake line communicated with a right brake, and a left-right cross-over valve operable to open and close communication between the left and right brake lines. The hydraulic circuit also includes a left shutoff valve between an outlet of the left brake valve and the left brake line, and a right shutoff valve between an outlet of the right brake valve and the right brake line. | 01-01-2009 |
20100201191 | Power Supply For By-Wire System - The invention relates to an electric power supply system for a by-wire vehicle system. There is a need for a power supply system which allows the integrity of the battery and alternator to be monitored. A vehicle electric power supply system includes a battery, an alternator, a key operated switch and at least two electronic control units (ECUs). A battery line is connected to the battery, to the second ECU, and to the key switch. An alternator line connects the alternator to the first ECU and to the key switch. A relay includes a relay switch which opens and closes a connection between the battery line and the alternator line. A relay coil is energizable to cause the relay switch to connect the battery line to the alternator line. Energization of the relay coil is controlled by one of the ECUs. This ECU causes the relay coil to move the switch element disconnect the alternator line from the battery line so that voltage from the alternator and battery can be independently tested. | 08-12-2010 |
20110024601 | Suspension System Having Active Compensation for Vibration - A suspension system for a seat of a vehicle comprises a base, a linkage, and a seat attached to the base via the linkage. A pneumatic shock absorber provides a respective resistance level against movement of the seat with respect to the base based on a corresponding pressure level of air or gas within the pneumatic shock absorber. A set of cylindrical members are spaced apart beneath the seat. A tension member is arranged to engage the cylindrical members. The tension member is attached to the seat via a bracket. An electric motor is capable of driving one of the cylindrical members. A first sensor is arranged to detect first sensor data associated with an instantaneous position of the seat versus time. A controller generates a first control signal for the electric motor to change a height of the seat in opposition to a change in the instantaneous position of the seat and a second control signal to change the pressure level. | 02-03-2011 |
20110316327 | Brake Control System For Dual Mode Vehicle - A brake control system is provided for a utility vehicle having manned and unmanned operational modes. The brake control system includes a hydraulically operated brake. A manually operated brake circuit and an electro-hydraulic (E-H) brake circuit are connected to the brake. The E-H brake circuit includes a pump, a solenoid operated inlet valve, an accumulator, and first and second solenoid operated brake valve connected between the brake and the inlet valve. A first CPU is operatively connected to the inlet valve and to the first brake valve. A second CPU is operatively connected to the inlet valve and to the second brake valve. An accumulator pressure sensor senses the accumulator pressure. A brake pressure sensor senses brake pressure. The first and second CPUs control the inlet valve and the brake valves as a function of the sensed accumulator pressure and brake pressure. | 12-29-2011 |
