Just quick question to see if anyone else has had this problem. We run a Takeuchi tl 130 great machine no mechanical problems but one side has thrown the track three times. Sometimes it will run 2 hrs before throwing, just last week it ran 25 hrs in three days and threw on the third day. The tightness was checked about 1.5 hrs before it threw the track. Could some of the inner teeth be wore down allowing it over the pulleys? The track appears in good shape all over and has about 200 hrs left in it i would guess based on our normal use. It always throws to the inside under the machine. Needless to say were getting faster at getting it back on and tightened but is there something im missing. i will probably replace with new track prematurely, but wanted to make sure its not a pulley problem. Machine has 1036 hrs total. tracks replaced last at 600 hrs. undercarraige looks to be in good shape. all around a clean machine.
