Abstract
Abstract A trailer for use in transporting a harvesting machine having a laterally shiftable tongue is disclosed wherein the trailer has transversely extending loading ramps pivotally connected to the load platform of the trailer to permit the harvester to be elevated from the ground level onto the load platform. An elevating linkage interconnecting the load platform and the pivotably ramps is engageable with the harvester wheels to affect a raising of the load ramps when the harvester has been properly positioned on the trailer platform. The load ramps are articulated to compact the transport position of the load ramps, thereby minimizing the transport width of the loaded trailer. The draft connection between the loaded trailer and its prime mover is the laterally shiftable tongue of the harvester positioned on the trailer platform.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
239 words
A trailer for transporting a wheeled harvester comprising: a wheeled frame for mobile movement of said trailer over the ground along a direction of travel; a platform supported by said frame at a position elevated above the ground; ramp means pivotally connected to said platform and movable in a plane substantially perpendicular to said direction of travel between a ground engaging position and an elevated position, said ramp means permitting said wheeled harvester to be transported from the ground to said platform when in said ground engaging position, said ramp means including a pair of ramp members pivotally connected to said platform and movable in corresponding planes perpendicular to said direction of travel, each said ramp member supporting a corresponding wheel of said wheeled harvester; and elevating means supported on said platform and connected with said ramp means to be engageable with said wheeled harvester to cause a movement of said ramp means from said ground engaging position to said elevated position when said wheeled harvester has been elevated onto said platform, said elevating means including an engaging member pivotally mounted on said platform and positioned to be engageable with the harvester to effect pivotal movement thereof, said elevating means further including a connecting link interconnecting said engaging member and said ramp members to transfer pivotal movement from said engaging member to said ramp members to raise said ramp members from said ground engaging position to said elevated position.
Claim 2
Dependent Claim
239 words
A trailer for transporting a wheeled harvester comprising: a wheeled frame for mobile movement of said trailer over the ground along a direction of travel; a platform supported by said frame at a position elevated above the ground; ramp means pivotally connected to said platform and movable in a plane substantially perpendicular to said direction of travel between a ground engaging position and an elevated position, said ramp means permitting said wheeled harvester to be transported from the ground to said platform when in said ground engaging position, said ramp means including a pair of ramp members pivotally connected to said platform and movable in corresponding planes perpendicular to said direction of travel, each said ramp member supporting a corresponding wheel of said wheeled harvester; and elevating means supported on said platform and connected with said ramp means to be engageable with said wheeled harvester to cause a movement of said ramp means from said ground engaging position to said elevated position when said wheeled harvester has been elevated onto said platform, said elevating means including an engaging member pivotally mounted on said platform and positioned to be engageable with the harvester to effect pivotal movement thereof, said elevating means further including a connecting link interconnecting said engaging member and said ramp members to transfer pivotal movement from said engaging member to said ramp members to raise said ramp members from said ground engaging position to said elevated position.
Claim 3
Dependent Claim
26 words
