Eric is right, the kick stands should be on the most forward loader arms. They are held in the stowed position by little safety clips.
When I bought my tractor the dealer suggested I remove the stands in case the clips fall off then the stand would fall down a puncture the tire.
I never took them off and I belive I will have better chances of winning the lotto then the clip falling out.
Look at your forward loader arms just aft of the bucket hinge and you will most likely see a couple of non threaded studs sticking out. That is where the stands would be hinge mounted. Keep following the loder arm back about three feet (or so) and you will see another stud with a small hole through it. That is the location that held the stand in the retracted position when not in use.
Bummer indeed if the prvious owner chucked them, or maybe they were stolen.
