I used the John Deere red dye mentioned above in my former L3200. Half the jar worked fine & turned thing nicely visibly pink.
Oil seals in an engine or tranny are are usually pressed in & designed for practically no pressure. Any noticeable pressure could cause them to leak or pop out. If you raise or lower hydraulics it can cause a rapid change in oil levels. With a large amount of air space things can vent out with minimal pressure build up. If it's full of oil with no air you can get a massive pressure spike as the vent can't can vent oil fast enough.
Not likely but probably not a risk I'd want to take. Half an hour to drain & refill vs many hours at best & splitting the tractor at worst to replace a seal.
