A washing device is provided for removing debris from an underside of a mower having a multi-chamber cutting deck. The device includes a mounting apparatus allowing the device to be attached to a flange of the deck. Connected to the mounting apparatus is an assembly for dispersing liquid such as water and delivering the water to all portions of the underside of the deck. To accomplish this delivery, the assembly includes first and second liquid dispersion plates attached with each other and also connecting with the mounting apparatus to allow the delivery of water therethrough. Provided in one of the plates is a channel having divided end portions which elevate water upon contact so as to lift the water over an included cutting blade. Coupled with this plate is yet another plate enabling connection of the dispersion assembly to the deck and also providing a vent between the two plates. Creation of this vent then allows an emission of water reaching across the width of each of the included chambers. Interaction between an elevated distribution of water reaching across the width of the deck together with simultaneous engagement of the blades results in a swirling effect permitting water to reach the entirety of the deck underside.

A tensioning assembly is provided for a synchronous belt drive on a mower deck. A plurality of idlers are mounted for rotation on bracket. One end of the a bracket engages an abutment surface mounted on the deck which restricts its movement, whereas a second end of the bracket is acted upon by a tensioning member which acts in substantially the same direction as the abutment surface. The bracket includes an elongated slot disposed between one of the idlers and the abutment surface, and a member fixed to the deck is engageable with the slot for confining movement of the bracket.

A fastening assembly is adapted for attaching a composite insert to a mower deck. The insert has an opening extending therethrough and a recessed portion adjacent the opening. The recessed portion has a shoulder and a first abutment surface. The assembly includes a spacer receivable in the recessed portion adjacent the shoulder. The spacer has a passage therethrough alignable with the opening in the insert, the passage having a second abutment surface. The spacer also has an outer periphery, a portion of which forms a third abutment surface alignable with the first abutment surface for non-rotatable engagement therewith. The assembly also includes a fastening member which has a head and a shank. The shank includes a threaded portion and a further portion adjacent to the head. The further portion has a fourth abutment surface engagable with the second abutment surface whereby the fastening member is non-rotatably receivable within the spacer passage and the insert opening.

A tensioning assembly is provided for a primary drive employed in supplying rotary power from a vehicle to at least one sheave associated with a blade on a mower deck which, upon being driven, creates a tight side and a backside in a belt on opposite sides of a sheave. A bracket is pivotably supported on the mower deck and carries rotatably thereon first and second idler pulleys on respective first and second portions of the bracket. The first pulley engages the tight side of the belt, and the second pulley engages the backside of the belt. A resilient member is operatively coupled to the bracket for biasing the first and second pulleys mounted thereon toward a tensioning position wherein each of the first and second pulleys effectively lengthen a path of the belt, thereby tensioning the belt.
