PROBLEM TO BE SOLVED: To provide a rotary lawn mower having a frame supported by a plurality of wheels for movement over the ground and a rotary cutting deck assembly. SOLUTION: The invention relates to a swing out arm for rear rotary deck wherein a support bracket assembly is pivotally coupled to the frame for movement around an approximately vertical axis. A telescoping arm is pivotally coupled between a support bracket assembly and the rotary cutting deck assembly and is adjustable into at least two lengths. A driving part is pivotally coupled between the support bracket assembly and the telescoping arm and is operable to move the rotary cutting deck assembly between a non-cutting position and a cutting position and further capable of retracting the telescoping arm between the at least two lengths to permit the rotary cutting deck assembly to be swung to a side of the frame for easy inspection, maintenance, and adjustment.
