A lift system and method for transporting agricultural implements. The lift system includes a pair of lower linkage arms, an upper link, and at least four carriage wheels for transporting the lift system along carriage guide rails of a trailer frame. A load lift assembly is mounted on the trailer and is movable between lowered, loading position, a raised position, and a transport position. It is capable of connecting to a load having a three-point hitch. A gas strut may optionally be equipped to aid in the lifting process. A telescoping light bar may be included to increase safety while in transport.

1. A system for placing a load on a vehicle including a vehicle frame, which load-placing system comprises: a load lift assembly having a first, lowered position for connecting to a load, a second, raised position with said load lifted above a level of said vehicle frame, and a third, transport position with said load positioned over and connected to said vehicle frame;a lift actuator connected to said load lift assembly and configured for moving said load lift assembly between its lowered and raised positions;a transfer actuator connected to said load lift assembly and configured for moving said load lift assembly between its raised and transport positions axially along said vehicle frame;said load lift assembly including a lower linkage assembly including a pair of lift arms configured for connecting to two points of said three-point hitch;said load lift assembly including a top link configured for connecting to a third point of said three-point hitch;said top link being pivotally pinned to a pair of mounting brackets affixed to said load lift assembly;a hydraulic reservoir assembly configured to operate said lift actuator and said transfer actuator;a motor assembly configured to provide power to said hydraulic reservoir assembly;a control assembly configured to send control signals to said hydraulic reservoir assembly;a first hydraulic arm connected to a front end of said vehicle frame, said hydraulic arm configured for moving said load lift assembly between said second, raised position in proximity to a rear end of said vehicle frame and said third, transport position in proximity to said front end of said vehicle frame; anda second hydraulic arm configured to pivot said lower linkage assembly about said lift arm weldment. 2. The load-placing system according to claim 1 wherein said load includes a three-point hitch and said system includes: said lower linkage assembly including a lift arm weldment, said pair of lift arms affixed to said lift arm weldment; andsaid lift arm weldment pivotally engaging at least one mounting bracket affixed to said load lift assembly. 3. The load-placing system of claim 1, which includes: a pair of carriage guides mounted on said vehicle frame in proximity to a respective side of said vehicle frame;said carriage including a pair of carriage wheels each rollingly engaging a respective carriage guide; andsaid pair of carriage guides configured to guide said load lift assembly longitudinally along said vehicle frame between said first, transport position and said second, raised position. 4. The load-placing system of claim 1, which includes: a stabilizer arm assembly connected to said frame and adapted for stabilizing said frame while said load is in said raised and transport positions by interlocking with a weldment receiver mounted to said lower linkage assembly; andsaid stabilizer assembly being movable between a locked position engaging a stabilizer arm receiver, and a disengaged position disengaged from the stabilizer arm receiver.
