Snap-In (Snap-End) Ledger Remove & Replace on John Deere 350 & 450 Sickle Mowers 

Here's a quick tutorial and confidence booster on how to Remove & Replace Ledger Plates in the Rock Guards of the John Deere 350 & 450 Sickle Mowers that use Snap-In (Snap-End) ledger plates. The John Deere part number for the Deere Ledger Plates is H31813
After removing the ledgers, I cleaned the cavity that receives the new ledgers so rust and debris did not interfere with a good seating/fit.
My rock guards appear white/grey because I touched them with Rustoleum Rust Reformer.
