Ken: those TracksPlus tracks look pretty skookum. Why are the McLaren so much heavier? More pad area? Thicker all the way around? Do you anticipate them last longer than the TracksPlus? Why is their double weight a + or -, depending on app? (A reference to heavier lasting longer?) The snow packing happened w/ which brand of tracks? Sorry for all the questions! john
McLaren use more pads for a given wheel base and the pads weigh more, but they have less ground surface contact area. Which makes them really punch into the ground, that gives great traction but is hard on the surface (especially if its grass)
McLaren tracks run smoother on hard surfaces because there are more pads.
More weight is good and bad depending on the applications. The heavy track counterweights the machine and lowers the center of gravity so for some jobs thats a plus.
It also sinks you more on soft ground, so there its a minus. They are harder to wrestle onto the machine and do up. So if you remove and install your tracks often its a minus. (also conside how many flat tires you have a year when thinking about this, though tracks should prevent some flat by protecting the tire, more so with the Tracks plus as they cover the tire more with the bigger pad)
You have to use the tool supplied with McLaren tracks as they are just too heavy to man handle. The tool works farely well provided you keep the dirt off the thread, which is not easy to do when field installing dirty tracks. Tracks plus are lite enough a 1" ratchet strap is all you need to pull them together. Having acces to a air compressor and deflating the rear tire until they are done up helps with either brand.
Less weight and a larger pad is = to more floatation on soft ground. Tracks plus in theory also consumes less hp and fuel to operate as the engine has to carry the extra weight around. The diffence is not huge though.
Tracks plus also uses a 5/8" pivot pin where McLaren is @ 9/16" (must be metric) Tracks plus floats the pin in both the pad and the side link, it is free to turn in either piece.
Mclaren locks their pin to the pad isolating the wear in the side link. So the pad does not wear at the pivot point but the side link wears twice as fast as it must take all the pivoting in one spot.
As for life expectancy the jury is still out, hopefully the more expensive McLaren last long enough to justify the extra price with more hours of life. But in the end I think its more prudent to buy the track that suits your needs the best.
