A power and cooling assembly is disclosed for use with a vehicle having a deck for a rotatable tool such as a mowing blade. An electric motor is mounted on the deck and used to drive the blades by an output shaft. A circulating pump is connected to a housing of the electric motor and is also driven by the electric motor. The circulating pump is hydraulically connected to at least one sump on the vehicle and at least one electrical component of the vehicle to provide cooling thereto. Additional cooling pumps may be provided on the vehicle and may provide cooling to additional electrical components.

A light-weight portable hydraulic system for engagement with equipment requiring hydraulic fluid to operate. The system includes a reservoir; a pump and an oil filter engaged with each other. One or more handles are provided on the system so that the system may be carried by a single individual or may be lifted onto or off of a supporting unit upon which the system is mountable. A suitable supporting unit may be a zero-turn stand-on mower. An input shaft for the pump is operatively engaged with the engine of the mower and the pump is powered by that engine. The system is selectively connected to the equipment requiring hydraulic fluid for operation, such as a mower attachment, by way of hydraulic hoses that quick connect to ports on the pump. The system may be engaged with or disengaged from the mower in around thirty seconds and without tools.

A method and system of operating a machine harvester that presents an improved solution for preventing clogging. There is provided simultaneous measurement of at least a parameter of a base-cutting set, of at least a parameter of a chopping assembly, and of a position of at least a floating roller of a conveyance system. Based on comparisons of the parameters measured and reference values, during a pre-defined time interval, it is possible to manage a propulsion speed of the machine harvester and to manage a rotation speed of cutting disks of the base-cutting set and of billet-cutting blades of the chopping assembly.

A grounds maintenance vehicle is disclosed. A vehicle frame extends between a first end and a second end in a longitudinal direction. A prime mover is coupled to the vehicle frame. A hydraulic pump assembly is coupled to the vehicle frame, where the hydraulic pump assembly is in mechanical communication with the prime mover. A hydraulic fluid line has a first end and a second end. The first end is fluidly coupled to the hydraulic pump assembly. A drive wheel motor is fluidly coupled to the second end of the hydraulic fluid line. The first end of the hydraulic fluid line extends longitudinally outward from the hydraulic pump assembly in a direction away from the prime mover.

A cutting system for a harvester, the cutting system including a knockdown roller, at least two row dividers, at least two base cutting elements, and at least two inner base cutting discs. Each of the at least two base cutting elements is disposed in the structure of a respective one of the at least two row dividers. Each of the at least two inner base cutting discs is disposed behind the knockdown roller. The cutting system further includes two arms and a lifter roller. Each of the two base cutting elements is connected to a respective one of the two row dividers by a respective one of the two arms. Each of the two base cutting elements is positioned entirely forward of the knockdown roller and the lifter roller.
