Installation Tips
(1 hour15 minutes)
For the RDTH72 finish mower its best to do this while attached to the tractor to allow lifting to access the bolt heads under the mower deck when removing the large center bracket. The nut holding the idler is a bear. Air tools were not available so I used a breaker bar. Clean things up while its apart and scrape under the deck. Fairly easy job.
