Hi Guys, I've got a 763 with the Goodyear Trackman Tracks, a ott rubber track. Need em, love, can't live without them! They were on the machine when I bought it , now up to 1000 hrs and no problems at all. Will say they are better on flat mud than muddy slopes, but they have given me more hours of work after rain than I would have had with a tired machine. Have been pondering the steel ott chain type for the spring this year, but only for new construction sites, has anyone seen the type I'm referring to? They are on ebay for $500.00 and have a little video that is pretty impressive.
