Looking for anyone who owns a drum mower for quite a while now and what your thoughts are on them? Do they hold up well? Pro? Cons? Brands? We've used a IH 1190 mower/conditioner for years now, we mow a little over 50 acres a years and it's slow going, farming is not our day job and it starting to weigh down on us taking 4 or 5 hours to mow a field.
