brings back memories of spending many hours on my dads Case 4890 in the mid 80's, pulled a 12 bottom plow, a 40' chisel plow, 80' harrow, 40' disc, and cultivator but can't remember the size of that.. i think the 4890 was around 250hp, was nice machine even had a tape deck! What i loved most about it was the options on the articulator, the crab position was the most fun to play around with but i don't remember it being that useful in the field.. he farmed just south of the Manitoba/ND border..
nice pics...
