From what we read and were told the 3600 was more prone to have the frame snap from the liquid/weight, a 3650 was heavier built and better, but we really wanted a 3660 and finally found one. Took a while. It had the 2 300 gal tanks in the center and we added 2 200 gal wing tanks. Still won't go down the road with anything in the center tanks and we fill in the field. To me just seems like with liquid, especially if the planter boxes are full of seed, that's a lot of weight and stress on the pivot components. Happy with the 3660 and glad we settled on one. |
