Any suggestions for helping prevent getting numb hands from doing alot of trimming? My hands tend go numb and weak, and I get the shakes for a few hours after trimming. Then the next day my wrists are sore when I wake up. Any suggestions? I was thinking maybe a padded grip, or padded gloves. Anything short of getting a different trimmer? Does any body make a trimmer with vibration reduction features? Mine is a JD straight shaft, can't think of the model#.
