I have a 720 w/rear PTO and w/3 point. Also heavier front steering parts.
What would be the Model number for this one?

If it has a shifter lockout knob, it would be a late model 720. You can look at the tag on the right side of your frame to see what the product no. and serial number is and then match up with the chart I posted.
