I've been wondering how the new/newer Case-IH Farmall A/ NH Workmaster series tractors compare to the Case-IH Farmall C/ NH Powerstar Tractors compare. I know the C/ Powerstar units are a little nicer with more options and features, but are they built better and more durable for the long haul or are they mostly just a upscale A/ Workmaster? This would be a front loader/hay baling machine.
