Abstract:
1. A ride-on lawn mower comprising: a vehicle frame coupled to at least two wheels and configured to support an operator in an operator position; a front-mounted cutting deck comprising a first cutting blade housed in a first cutter housing and arranged for rotation about a first vertical axle, a second cutting blade housed in a second cutter housing and arranged for rotation about a second vertical axle, and a third cutting blade housed in a third cutter housing and arranged for rotation about a third vertical axle; a first electric motor coupled to the first cutting blade to drive rotation of the first cutting blade; a second electric motor coupled to the second cutting blade to drive rotation of the second cutting blade; and a movable arm coupling the front-mounted cutting deck to the vehicle frame, wherein the movable arm is operably coupled to only the third cutting housing of the first, second, and third cutting housings of the front-mounted cutting deck, wherein the first vertical axle and the second vertical axle are spaced apart from each other by a transversal distance measured perpendicular to a longitudinal axis of the ride-on lawn mower, wherein the first cutter housing is rotatably coupled relative to the movable arm via a first support arm to enable rotation of the first cutter housing in a plane, the first support arm being pivotally hinged relative to the third cutter housing to enable movement of the first cutter housing out of the plane, wherein the second cutter housing is rotatably coupled relative to the movable arm via a second support arm to enable rotation of the second cutter housing in the plane, the second support arm being pivotally hinged relative to the third cutter housing to enable movement of the second cutter housing out of the plane, wherein the first vertical axle and the second vertical axle are coupled to the movable arm such that the transversal distance between the first vertical axle and the second vertical axle can be adjusted by the operator to increase or decrease, wherein the front-mounted cutting deck is raisable to a substantially upright position via the movable arm to assist with servicing or storage of the cutting deck, and wherein the first electric motor and the second electric motor move with the first vertical axle and the second vertical axle, respectively, when the transversal distance is increased or decreased.
