I used the 10 HP Troy-Bilt chipper yesterday to chip up my brush pile. Just as I finished, it started vibrating badly, shut it down, took it to the shop for repairs. found a broken "flail" . Ordered a new one @ $20.50, should be here Friday. Since I have it apart, thought it would be easier to service, fresh oil change & clean air filter. Noticed the brace on the back of the muffler was broken loose, took it off. The inside Torx bolt was a bear to get to, but fortunately wasn't overly tight! Welded the brace back on & re-installed the muffler. Noticed the rubber breather tube was pulled out of the air cleaner box, put it back & cleaned the dirt out of the box!
Now, just wait for the new "flail" to arrive! ~~ Lowell
