Abstract: A controller for hydraulic system of a work machine is provided. The controller is configured to perform a worktool disconnect routine to reduce pressure in a first worktool line and a second worktool line of the hydraulic system. The hydraulic system comprises a spool valve, a first worktool port connected to the spool valve by the first worktool line, a second worktool port connected to the spool valve by the second worktool line, a high pressure flow source of hydraulic fluid connected to the spool valve by a high pressure line and a low pressure tank line connected to the spool valve, the low pressure tank line at a lower pressure than a pressure of the high pressure line.

Abstract: A hose deployment device (1) including a base (3, 300) having sides (4, 400) which in a contracted configuration secure together to define a space to receive a hose (10, 100). The sides (4, 400) in an expanded configuration extend outwardly away from each outer to provide an opening through which the hose (10, 100) can move. Fastening means secure a hose inlet valve and a hose outlet nozzle (27) to the device. Strap means secure a hose to the base in the contracted configuration. Upon application of a fluid pressure to the inlet valve the hose expands urging the strap means to release the hose from the base.
