Hydraulic sickle knife drive on a combine header

A sickle knife drive for a cutter bar on a header of an agricultural combine, the sickle knife drive comprising:

• a hydraulic drive manifold having a plurality of connections comprising a first pump connection, a first motor connection, a second motor connection, a combine connection, and a manifold case drain connection, the combine connection being configured for connecting to the combine, the manifold case drain connection being configured to connect to the combine;
• a first pump in fluid connection with the first pump connection and configured to mechanically couple to a power transmission device, the first pump comprising a first pump case drain being configured to connect to the combine, the first pump creating at least one system state comprising at least one of a forward state, a reverse state, and a neutral state, the hydraulic drive manifold comprising a forward position during the forward state, a reverse position during the reverse state, and either the forward position or the reverse position during the neutral state;
• a first motor in fluid connection with the first motor connection and configured to drive a sickle knife gear box, the first motor comprising a first motor case drain being configured to connect to the combine, the first motor operating in a reverse direction when in the reverse state with a reverse flow through the first motor;
• and
• a second motor in fluid connection with the second motor connection, the second motor providing a flow that supplements fluid in a circuit between the first pump and the first motor in the forward state and no flow during the reverse state, the second motor not supplementing the reverse flow,
• wherein the hydraulic drive manifold is configured to divert a low flow supplied to the second motor during the forward state to the first motor during the reverse state.
