Use 60# fishing line. Put the line through the hook on the end of the spring, doubling the line back towards you. Secure the line to something which will serve as a handle to pull on. Make SURE you secure this very well. Pull the spring into position and (I hate to tell you this part): Have your bestest lady friend put the hook into the slot/hole on the mower deck. Or better yet: Just go buy a six-pack, some steaks, fire up the grill and invite your best buddy over to put the spring into the hole, then celebrate the mission completed.
