A draper platform having a direction of travel through a field ("V") and a leading edge, comprising: an elongate frame (102, 104, 106), said frame being elongate and disposed to carry crop in a direction transverse to the direction of travel through the field; support arms pivotally coupled to the frame and extending forward therefrom; a reciprocating knife disposed at the leading edge of the draper platform and extending substantially the entire width of the draper platform; a left side conveyor disposed behind the reciprocating knife and supported on a first plurality of the support arms and having an endless belt (122, 124, 126) disposed to carry crop from the left side of the draper platform to a central region of the draper platform; a right side conveyor disposed behind the reciprocating knife and supported on a second plurality of the support arms and having an endless belt (128, 130, 132) disposed to carry crop from the right side of the draper platform to a central region of the draper platform; a center conveyor disposed between the left side conveyor and the right side conveyor, said center conveyor having an endless conveyor belt and at least two rollers on which the endless conveyor belt is supported and about which the endless conveyor belt reverses its direction of travel; characterised in that the center conveyor is supported on two adjacent support arms (246A, 246B) and wherein the center conveyor is releasable from a first support arm of the two adjacent support arms (246A, 246B) to pivot downward away from the first support arm of the two adjacent support arms a distance sufficient to slidably remove the endless conveyor belt from the center conveyor in a direction parallel to the axes. an elongate frame (102, 104, 106), said frame being elongate and disposed to carry crop in a direction transverse to the direction of travel through the field; support arms pivotally coupled to the frame and extending forward therefrom; a reciprocating knife disposed at the leading edge of the draper platform and extending substantially the entire width of the draper platform; a left side conveyor disposed behind the reciprocating knife and supported on a first plurality of the support arms and having an endless belt (122, 124, 126) disposed to carry crop from the left side of the draper platform to a central region of the draper platform; a right side conveyor disposed behind the reciprocating knife and supported on a second plurality of the support arms and having an endless belt (128, 130, 132) disposed to carry crop from the right side of the draper platform to a central region of the draper platform; a center conveyor disposed between the left side conveyor and the right side conveyor, said center conveyor having an endless conveyor belt and at least two rollers on which the endless conveyor belt is supported and about which the endless conveyor belt reverses its direction of travel; characterised in that the center conveyor is supported on two adjacent support arms (246A, 246B) and wherein the center conveyor is releasable from a first support arm of the two adjacent support arms (246A, 246B) to pivot downward away from the first support arm of the two adjacent support arms a distance sufficient to slidably remove the endless conveyor belt from the center conveyor in a direction parallel to the axes.
