An agricultural planter has a chassis with a tool bar and at least one row unit. Each row unit is carried by the tool bar and has a fluid actuator and a linkage assembly connecting it to the tool bar. The linkage assembly and fluid actuator allows the row unit to be raised and lowered. A control module is operable to individually raise and lower each row unit on the agricultural planter using the fluid actuator in response to either a manual input, an automatically determined requirement or condition of the at least one row unit, or an automatically determined operating condition of the agricultural planter. The control module is further operable to prevent the raising or lowering of an individual row unit on the agricultural planter based on either a configuration of the agricultural planter or the potential occurrence of an undesirable weight or drag distribution.
