by the time you figure rops AND ps upgrade.. I bet you that you are in for 1500-2000$
might be cheaper to find a machine with all that stuff already.
if you don't want to loose any HP.. you will have to step up to a 4xxx+ model in the 3 cyl series.. or a 8xx/4000 4 cyl witht hat stuf already attached.
look thru the adds and see what the prices of loader tractors with rops and ps are then compair.
