Where is the best place to buy replacement tracks?
McLaren used to be one of our sponsors. Last time I was hunting for a set of tracks They had what was looking for, and the salesman was very helpful. I found a better price from the local dealer of the excavator brand I was working on though. Probably not the same quality as the McLaren tracks, but since the machine was only an occasional use machine and pretty near the end of its life span, the cheaper ones were what we used. The McLaren guy still calls every now and then to see if I'm looking for anything else, which a good salesman will do.
We have had good luck with Camoplast
