CA 2638951

A friction drive for an agricultural planter has a linear actuator, which may be hydraulically or pneumatically controlled, to selectively raise or lower a drive wheel into frictional engagement with a carrying wheel. A valve network is fluidly associated with the linear actuator and allows the operator or pilot to variably define the degree of frictional engagement. This allows the operator to vary the amount of frictional engagement of the drive wheel and the carrying wheel, the output of which is used by a material dispensing system to deposited planting material onto a planting surface.
