Installing 72" Deck Model 4115 on John Deere 2520

This is a step-by-step, hands-on walkthrough of reinstalling a Scag 72" mower deck (Model 4115) on a John Deere 2520, filmed by an owner doing the actual work. It covers aligning rock shaft arms, drill pins and locking rings, remounting the front wheel and spring tensioner, spacer placement, deck leveling, and the tricky belt reinstall. Useful for 2520 owners who already have this deck and need a practical reference for remounting it themselves.
