The file 'Ryobi 48v Zero Turn Control Arm Replacement 3D Printer Model' is (stl) file type, size is 75.6KB.
Breaking the Control Arm Handle (PN#HM-997144001 and/or HM-997145001) means replacing the entire $160+ assembly as the individual Control Arm attachment is not available for purchase.
It's quite easy to access, and easily disassembled, so I printed a replacement.
