Usually when your track starts sagging machine operators may think the track is just stretched out. So then just go buy a new track, right? WRONG! MAKE SURE YOU CHECK ALL UNDERCARRIAGE PARTS!! It's very likely that the sprocket and idler are worn out which is preventing proper tensioning. Not replacing these parts will shorten the life of the track. If you have questions about your idler give us a call and we will be more than happy to help out.
