We used to pull a 1000 gallon 120' wheel boom with a 4255 and at the same time my uncle had a 1000 gallon 90' suspended boom on a 4450. The suspended just required more watch when going through ditches because you tended to run faster through them than with the wheel boom. 4255 handled that big wheel boom sprayer just fine. No power problems and the sprayer transfered enough weight to the tractor. When it got muddy we did put the 7810 with duals on it..
