5 of 5 John Deere 757 Kawasaki motor replacement May 14, 2020
Reviewer: Bernd from Dowagiac, MI United States  
I have had this mower for 15 years and it was time for a new motor.  This was the correct motor and was very easy to swap.  Removed the old pulleys, voltage regulator, and muffler from the old motor and put on new motor.  Decided to use old starter because it still worked. Swapped the wiring harness which was super easy.  It took me about 4 hours from start to finish, which includes cleaning all the old parts.  Motor runs grreat and i didn't need to spend $13 Thousand on a new zero turn mower to use on the farm.
