Abstract: A folding frame for a drawn implement such as a hay rake is disclosed. The frame includes cushion fold cylinders, a lift cylinder, and a windrow width cylinder. The lift arms actuated by the lift cylinder lift the frame wings and engage a selector valve, providing an open circuit to either the fold cylinder or the windrow width cylinder, or both. During folding, when the cylinders reach the cushion region of their stroke, the pressure in the hydraulic circuit increases, resulting in a change in the force applied to the selector valve by the lift arm. By careful adjustment, this change in pressure will adjust the selector valve so the hydraulic circuit is open to both the fold and windrow width cylinders. Consequently, the windrow width cylinders extend, keeping the frame wings from colliding with the main frame.

Abstract: It is known that overshoot in fuel flow rate as a result of compensating for engine heat soak effects can create transient over values in desired thrust parameters. These over values may be displayed and/or utilised in other engine control systems, and although transient may create problems within the engine and apprehension with a user. By adjusting the normally calculated fuel flow rate to a fuel regulator by the introduction of a fuel flow adjustment dependent upon a variable which is related to heat soak effects it is possible to reduce the extent of overshoot as well as the transient time period of that overshoot to ongoing operational state. The variable used may be direct or indirect and will generally utilise a temperature sensor within the engine and/or other engine control procedures which may be extrapolated from such sensor values to provide a variable for heat soak compensation.
