International Classification:

A01D 3462

US Classification:

56249

Abstract:

A mechanism for shifting reel mower cutting units to a position whereat the undersides of the cutting units are exposed for service. A knuckle joint is provided for pivoting the cutting units as the lift arms are raised to thereby shift the cutting units to service positions. A connection point is provided between a yoke and the cutting unit which is located at the upper rear quadrant of the cutting unit's side frame for generally balancing the force distributed to the ground through the front and rear rollers during forward mowing operations.

International Classification:

F02M 35/10

Abstract:

A flexible airflow system providing customizable components for mounting, directing airflow and/or modifying airflow. The system may include a dual fan apparatus for providing heated or cooled air which is compact fit within limited spaces. The dual fan apparatus includes two axial fans on opposing sides of a thermal exchange component which operate in coordination to move air in one direction at a time through the apparatus. The dual fan apparatus increases airflow and thermal transfer efficiency through the thermal exchange component. The system may also include a flexible bracket system and/or a flexible ventilation system to facilitate custom configurations for the airflow system.
