Belt Drive System Having A Single Drive Motor For Multi-Bladed Rotary Cutting Unit For Mower

US Patent:
6389786, May 21, 2002
Filed:
Feb 18, 2000
Appl. No.:
09/507313
Inventors:
Rex R. Bergsten - Burnsville MN
Thomas F. Langworthy - Belle Plaine MN
Assignee:
The Toro Company - Minneapolis MN
International Classification:
A01D 3403
US Classification:
56 175, 56255, 56295
Abstract:
A riding mower having two side cutting units and a front cutting unit operatively connected to a traction frame. Each side cutting unit can pivot about a substantially vertical axis relative to the traction frame when impact shocks occur on the outer sides of the cutting units. A shock absorber cushions and absorbs such impact shocks, and resists the pivoting motion of the side cutting units, in a bi-directional fashion to be effective during forward or reverse motion of the traction frame. The mower also includes a front cutting unit. The cutting units, both the side cutting units and the front cutting unit, have multiple cutting blades and a single drive motor mounted on the cutting unit for driving all the cutting blades contained on that cutting unit. The drive motor is mounted coaxially on the blade spindle of one of the cutting blades and adjacent blades on the cutting unit are driven by one or more drive belts arranged in straight belt runs. The drive belts are identical in size so that common drive belts can be used on all the cutting units.
