Are you speaking from firsthand ownershipIJ The cost of ownership on my 485R is less than what it was on one 9600_9610 model combine. My dealer has always had the parts I needed (onhand or in 24hrs., Cat or no Cat),which has been very few compared to the competitive models I have owned (red and green) and no compalints about service and maintenance on my part or the dealer's, its just a simply machine to service (too many people fear the perceived complexity and are very quick to judge). With the one 485R, I am achieving an avg. of 15-20% more productivity vs. the previous two models (9600 and 9610) it replaced. In ideal running conditions 15-20% can easily be 30-40%. The tracks are a tremendous feature, both operational and cost savings, not only for compaction but for ride and efficiency too (the tracks simply glide across most ground conditions, using less energy to move forward). Too often many are far to quick to judge reliability, durability, productivity simply based upon perception alone ("look at all those belts, look at all those pulleys, those tracks cost too much, an electronic nightmare") - my neighbors all said that, to my disgust. Then, two had me help finish them up, one wanting me to do all of his white corn because he couldn't seem to reduce the damage from his green machine, all the while they noticed that my daily service took an hour less than their competitive machines. Don't knock what you don't understand.
