I just picked up a used 48 viking hydro. It seems to be in very good shape. What wear points should I be concerned about? The hydro filter looks like it's been there awhile. Everything else seems tight. This type of mower is a first for me. Hope to get a hang of running it without mowing over something I shouldn't. I bought this mower to replace my old grasshopper 12hp 42" deck zero turn for around the house mowing. I have a 2 acre rc airfield to mow also. I'm not sure this mower could mow that area in a timely manner. I will need a sulky to try. I cannot keep up with it for that long of a period.
