Sorry,I wouldn,t know what your tr99 is worth there are none over here in Ireland,Did get a look around a cx860 at a machinery show in Dublin last week.It certainly looks the part and has what I would guess is the best cab on the market, but in terms of physical size it is alot bigger than the tx64+ and two lexions we run at the minute.I hope to get a demo drive in a cx sometime during 2003 harvest and see how she stacks up against our new Claas 470R.
