we have a mx215 with 380 duals on the rear and 380 singles on the front that we use to pull a 24 row 20 inch planter 40 foot. we use to pull the planter with an mx200 with 320's duals on the rear single on the front. liquid fertilizer on the planter non ccs. i think the 380 tires are a better match for this planter. if went with a bigger planter i would go with tripples on the rear.
