One valve control

"My Precious" embodied in a test sample. Just one - not classical two - usual cartridge type proportional pressure reducer (regulator) controls conventional sectional distributor in fully proportional mode, for example, 3-way & 4-position spools with "true", i.e. physically middle neutral position: 

floating << lowering < neutral > lifting

The solution is tested as on a test bed in a laboratory as on a real front loader in real working conditions (building of a new factory).
