BM 2-speed motor shift circuit
BN Balances fluid flow from flow
divider/combiner valve BM to flow
divider/combiner valves BO and BP
BO Controls flow to non-steer end drive
motors in forward and reverse
BP Controls flow to steer end drive
motors in forward and reverse
BQ Controls fluid flow to flow
divider/combiner valves BO and BP in
forward and reverse
