The blade engagement cable on my old Noma riding lawnmower broke. The handle just flops back and forth. I see a small piece of broken cable were it is attached to the handle. There is thin wire with a spring and washer laying loose on the mower deck so it may be part of the setup. Does anyone have a diagram on this or a part number so I could get a new cable. I wasn't able to find anything online.The model # is E43T4020. Thanks
