I liked the pictures. I have only once baled with one of the Cat D4's, a 
very long time ago. The reason I did not do so more times was the speed 
of the tractor - not fast enough for travel between fields and areas. 
But unlike your land, this was on level fields. I noted in a past 
comment that Dean had said his father would not have liked the crawler 
in the Alfalfa fields. The interesting thing is that a Cat applies so 
little compaction that the damage level is much less than a wheel 
tractor. Your tractor has about 18 square feet of contact area from the 
tracks and that yields 5psi on the soil or hay. If it had the wide 
tracks then there is only 3psi of pressure. Compare this with a typical 
wheel tractor weighing 7000#, that unit applies between 30psi and 60psi 
usually....
