Question for 98J

I remember your posts on Red power and ACMOC
and that you farmed with a D5 .
I am looking at a used D5B LGP 1981 that is set at ( 180 hp?) .
Question is will this unit pull a 30foot field cultivator in near flat black
midwest soil ?
Am currently running it with 4wd with about 250 drawbar hp which it
pulls well at 6 mph.
Since your part of the country had a large # of these , what is
one worth there asking $17,500.00 ?
Like new bottom, 2hyd , Cab A/C
Thanks
JB
