Agricultural spreader

A method of controlling a rate of supply of agricultural material to at least one material spreading means of an agricultural spreader having material storage means and variable speed material conveying means operable at a variable speed for conveying said agricultural material from said material storage means to said at least one material spreading means, the method including providing said agricultural spreader with inclinometer means adapted to provide an output representative of a pitch of said agricultural spreader relative to a horizontal plane, the method further including providing said agricultural spreader with control means adapted to, in use, detect at least one input and to vary the speed of said variable speed conveying means in response to said at least one input in order to provide a required rate of supply rate of agricultural material to said at least one spreading means, wherein said at least one input includes said output from said inclinometer means.

A method of controlling a rate of supply of agricultural material to at least one material spreading means of an agricultural spreader having a material storage means, material conveying means for conveying said agricultural material from said material storage means to said at least one material spreading means and metering means including at least one aperture through which said agricultural material passes prior to or during said agricultural material being conveyed to said at least one material spreading means and operable to vary an area of said at least one aperture;

• the method including providing said agricultural spreader with inclinometer means adapted to provide an output representative of a pitch of said agricultural spreader relative to a horizontal plane, the method further including providing said agricultural spreader with control means adapted to detect at least one input and to vary the area of said at least one aperture of said metering means in response to said at least one input in order to provide a required supply rate of said agricultural material to said at least one spreading means, wherein said at least one input includes said output from said inclinometer means.

A method of controlling a rate of supply of material to at least one material spreading means of an agricultural spreader having material storage means, variable speed material conveying means operable at a variable speed for conveying said agricultural material from said material storage means to said at least one material spreading means, and metering means between said material storage means and said at least one material spreading means, said metering means including at least one aperture through which said agricultural material passes prior to or during being conveyed to said at least one material spreading means and operable to vary an area of said at least one aperture, the method including providing said agricultural spreader with inclinometer means adapted to provide an output representative of a pitch of said agricultural spreader relative to a horizontal plane, the method further including providing said agricultural spreader with control means adapted to, in use, detect at least one input and to vary one or both of the speed of said variable speed conveying means and the area of said at least one aperture of said metering means in response to said at least one input in order to provide a required rate of supply rate of agricultural material to said at least one spreading means, wherein said at least one input includes said output of said inclinometer means.
