How to Mount a 36-Inch Mower Deck on a JD 180

When you look at the 36-inch mower deck for the John Deere 180 lawn tractor, you will see two sets of linkage bars on each side of the mower deck and a loose drive belt on top of the deck. To connect the 36-inch mower deck to your John Deere 180, you must connect the linkage bars to the pins mounted under the lawn tractor, and you must connect the drive belt on the mower deck to the drive pulley mounted under the engine. This is all part of routine maintenance for a John Deere, so the process is user-friendly.
