I saw a guy unload a 763 Bobcat with a set of those chains. I laughed too. It reminded me of Jacob Marley dragging his chain. Made noise and looked real, real, flimsy. The point of tracks is giving your protection and flotation. Those tracks' pads looked so thin and they ran so loose I couldn't believe they were doing anything except waiting to get hung up on something like rebar or a sharp stump.
I have a set of used Loegering trail blazers. I have had them on an 863c, 863G, s250, s300. Rebuilt a few components here and there. Replaced a few pins, a FEW broken links, and worn bolts. Tracks still do their job after nearly 7 years and thousands of hours on rock and limestone. I just took them off last month because I wanted to reduce the weight on my trailer and stop tearing up the ground so much. You CAN'T go wrong with good tracks from a good brand.
Tried a pair of grousers with replaceable pads on an S250. Ended up practically giving them back to the dealer they stunk so bad. The grade 8 bolts (2 of them) that hold the pads on sheared off in rocky terrain. The cast iron tracks were heavy, too. I like the Loegering because they are made of "magnesium?", I think. Durable, only 450 lbs. per side, and not too hard to take on or off and they only cost about $3500 new.
