This is our ST270, still working away on our farm, we have had it about 15 years,traded a  Case 2670 for this Cougar. It has been a workhorse, has about 8900 hours.

There are a few of these green Steigers around here, I see Steigers in road construction and pulling tile plows too. 

It's nice to see I am not the only one trying to wear  one of these out.   I will get a newer tractor when this one is no longer doing the job, (could be a while)
