Season's Greetings to All
Just had a JD TRS-21 snow thrower in my shop with a few problems, one of which was worn rubber paddles on the auger. JD only sells the complete auger assembly for $200.00 plus, so I figured I should be able to do better than that. A little research showed this unit was actually built by Murray and Stens carries replacement rubber for Murray for around $80.00 retail. Long story short, drilled out all the rivets and secured new Stens 780-340 rubber paddle set to auger with ¼" x ¾" carriage bolts and flange lock nuts with a drop of medium strength thread locker on each bolt just in case.
Net result, customer had all new rubber on his snow thrower for less than 2/3 the price of new auger from JD which would have required labour to install on top of that. Merry Christmas and all the best,
