The VTS system will have much more traction on slippery surfaces then any tracks over tires will. The VTS system applies more even weight distribution. With the Track over tires the tracks between the tires have no weight pushing them down on the ground so that part of the track is not as useful as the parts that are under the tires. Also when in heavy mud and hilly work the tires get wet and like to spin out inside the tracks. Then you are just stuck.:BangheadThe Loegering VTS system looks good, just emailed for a quote, i would expect them to be pretty expensive...............
But somehow i would expect the grouser bar tracks to have more traction going up slippery clayish soil......................be interesting to see what price loering come back with.
I agree totally with you on that one and have done it myself to a Cat 262 where I actually broke the bolts on the drive unit that holds on the tire. Also though with air filled tires I have blown them off the rim and turned the rim into a pretzel by getting a rock on the tracks between the tires and running over it. I just don't like tracks over tires.Warning, solid or foam filled tires and tracks can be a bad combo. If a rock get between the track and the tire, the tire has no give and the stress goes onto the axle occasionally busting that. My suggestion is to use a slime lined tire like galaxy's lined tires. Nails will not cause leaks, and you get the cushion benefit of air. Of course if you really want a track machine, a ctl is the way to go.
