I am frustrated with track quality.....our ground in North Alabama is the worlds worst on tracks. I have sold all brands of replacement tracks and it seems lately the quality everyone is putting out sucks. My customers use to average 800 to 1200 hours on tracks.......now they are averaging 550 to 800 hours...it is driving me crazy. I am now selling Trellborg tracks. So far they have held up well....We will see. If I ever find a track that will stand up to our ground they will have my business for life.....Trellgborg has promised that we will be happy with them and have made every effort to take care of me. We will see. Should be able to tell by next spring.
