Abstract: A hydrostatic transmission subassembly for a vehicle includes an adapter manifold and a hydraulic pump mounted to the adapter manifold. The pump includes a pump housing and a pump porting manifold including pump porting for communicating fluid to and from the pump. The adapter manifold may include a mounting section adapted for mounting to the vehicle and a fluid interface section extending from the mounting section. The fluid interface section includes a pump interface having pump interface porting, in which the pump interface engages with the pump porting manifold to fluidly connect the pump interface porting with the pump porting. When the mounting manifold is mounted to the vehicle via the mounting section, the mounting manifold supports the hydraulic pump. The fluid interface section also includes a motor interface having motor interface porting for fluidly connecting to a motor, which enables the mounting manifold to fluidly connect the pump and motor.

Abstract: An example hydrostatic transmission includes (i) a motor section having a motor interface; (ii) a pump section configured to generate fluid flow, where the pump section comprises a pump interface having a first pump port to provide fluid flow therethrough and a second pump port to receive returning fluid flow therethrough; and (iii) an interface block coupled to the motor interface and coupled to the pump interface so as to couple the pump section to the motor section, where the interface block includes internal fluid passage to facilitate fluid communication between the pump section and the motor section.

Abstract: An integral fan and airflow guide including a hub having a frusto-conical outer surface, and a plurality of fan blades circumferentially spaced apart about the hub and radiating outwardly from the hub. The frusto-conical outer surface having a plurality of circumferentially spaced apart slots that separate inclined segments of the outer surface to define respective airflow guide surfaces. The plurality of fan blades are integral with the respective airflow guide surfaces. The inclined airflow guide surfaces cooperate with the fan blades to direct impelled air axially and radially outwardly for improving the cooling of a machine component, such as a hydrostatic transmission, that is obstructed from airflow by a pulley or other obstacle.

Abstract: A brake apparatus for a mowing machine that includes a brake gear operatively rotatable with a rotatable member and a lock assembly for meshing with the brake gear to restrict rotation of the brake gear. A guide rail assembly is fixable relative to a support for supporting the rotatable member for rotation. The guide rail assembly guides a lock assembly movable between an unlocked arrangement and a locked arrangement. An actuator plate and the guide rail assembly jointly engage the lock assembly to effect meshing and unmeshing of at least one engagement member of the lock assembly, such as a roller or a jaw member, with the brake gear. The actuator plate is selectively rotatable about an axis of rotation of the brake gear relative to the guide rail assembly, where rotation of the actuator plate effects movement of the lock assembly between the unlocked and locked arrangements.
