This unit is in excellent shape and works as it should. 

The head gate is a few years older than the rest of the set up but works perfect. 

Can be modified to fit into many different locations. 

Access to both sides of the animal. 

Worth $6000 new plus the extras I have with it 

$5150 obo 

Can help load on to a trailer with skid steer. But you will need to bring help for disassembly.
