Abstract
A front loader arrangement includes a hydraulically sprung lift cylinder arrangement coupled between opposite loader arm sides and respectively mounting masts. In order to permit the masts to pivot freely about their pivotal connections with the loader arm sides to aid the coupling of the masts to respective mounting frames fixed to a carrying vehicle, the hydraulic system in which the lift cylinder arrangement is incorporated includes a device, including a shut-off valve and an accumulator arrangement for establishing a float condition in the lift cylinder arrangement after a source of hydraulic fluid and associated control valve is decoupled by separating a hydraulic quick coupler.
