A control system for a personnel carrier attached to a boom which is displaceable by pressure fluid. The control system comprises at least one hand operable controlled handle axially rotatable in a limited clockwise or counter-clockwise direction to cause the boom to be elevated or lowered, respectively. A control valve is associated with the control handle and has at least one adjustable pressure fluid control component therein to control the displacement of the boom. A movable linkage is secured at one end to the control handle and at an opposed end to the fluid control component whereby rotation of the control handle causes displacement of the control component to regulate the pressure fluid which in turn controls the displacement of the boom.

The apparatus comprises a delumper-sifter and a mixer used to prepare a mixture of peat and water which is placed in storage; the mixture is then passed to a forming device, is extruded in the form of continuous cylinder and is covered with a sheet of degradable paper; the covered product is cut up by means of a rotating spiral cutter, the rotational speed of which is synchronized with the speed at which the mixture emerges from the forming device, thus making it possible to obtain cylindrical extrusions of a predetermined length; the cut extrusions pass to a conveyor-distributor which arranges them in rows and then allows them to fall, in a vertical position, onto a supporting conveyor above which a drum, equipped with cylindrical protuberances, produces in the extrusions cavities in which seeds are subsequently placed and covered with sand; the final operation carried out by the apparatus is to group the seedling tubes thus produced and to wrap them in packages.
