Abstract
A cutting platform for use with an agricultural harvesting machine includes a plurality of platform sections. One or more of the platform sections include a cutterbar assembly which is movable in a localized manner in upwards and downwards directions. An endless belt has a leading edge. A plurality of belt guides each have a rear edge with an upper surface and a lower surface. Each lower surface partially overlies the leading edge of the endless belt. Adjacent belt guides have an overlap with a smooth upper transition and/or smooth lower transition at the overlap. A smooth upper transition has an absence of any discontinuities extending above adjacent upper surfaces, and a smooth lower transition has an absence of any discontinuities extending below adjacent lower surfaces.
