I have a T250 with 1800+ hours on it and it's on its 3rd set of tracks. The set that is on there now has about 75% life left. And before I get a "lesson" on how to turn correctly and so on and so forth, that machine has seen some very harsh terrain.
One project involved a natural 2:1 slope in chert, a weathered quartz and clay, that the only machine that would get down and back up was the CTL. If was a big job and we just had to sacrifice a set of tracks for it.
So I have averaged 500-600 hours for a set of CTL tracks
in the environments that I work in. Replaced the mini-ex tracks at 1800 hours for the first time. The tread had 30% life left but the T-bar links started popping out from the inside of the track, so we just ran it to failure, one track finally broke in 2.
I also have an older '01 Bobcat vib-roller. The only problem I have had with it is spinning the bearings out. I have replaced 1 before and have another one to replace now. The grease fittings on the older ones, like mine, is hard to access and in my situation I believe the bearing failure is due to lack of greasing and operator error (used by many, cared for by none - recently fixed that problem
). All in all a great little attachment for close quarters compaction. Mine is the padfoot version, but I have a smooth drum bolt on shell for it as well.
