Abstract
A self-propelled grain combine head is transported on a wheel supported trailer having an elongated lower support bar on which is mounted a pair of slidable head support units each having a bracket supporting a repositionable support member. Each support member has peripherally spaced different support surfaces for receiving frame members of different combine heads, and each bracket and corresponding head support member have a plurality of sets of alignable holes for receiving a pair of removable cross pins. A pair of hold down units are also slidably mounted on the lower support bar, and each unit carries a manually actuated ratchet winch having a flexible hold down strap. Each strap is connected to a combine head by a hook which may also receive a claw-type hook and a cross pin.
