Like most AG machinery. A Beaver for instance after landing on most AG strips if you hold the yoke full back you will get damagae to the mass/aerodynamic balancers on the end of the elevators from rocks. Likes of Thrush are weighted so the stick goes forward, gets very heavy if you hold the stick back all the time, heavy braking being an exception. Using reverse is another, unless the tails planted firmly reverse will exacerbate any movement. Usually you land in right spot so you don't have to brake heavily. Even empty an 802 goes over 3 ton, with an 8 usually once the tailwheels settled there's just no need to hold full back.
As I said before, yes "Usually" stick back in most aircraft.
