The spring that engages the deck broke. One end of the spring is connected with Deck engagement cable. so do I buy just the spring and take the cable off and put it thru the spring (one end) and the other end thru the Deck engagement cable bracket? Also, which spring shoud I buy - SKU: 732-04280A or SKU: 732-04287. Also, if I have to remove the cable, how do I do that (remove the battery casing etc).
