FLOOR JACK THIS IS A MUST HAVE IN ANY BIKE SHOP. IT ALLOWS EASY DISMOUNT OF THE ENGINE THAT CAN THEN BE ROLLED AROUND TO ANY LOCATION. IT ALSO MAKES IT EASY FOR THE ENGINE HOIST TO ATTACH TO. THIS ONE IS THE SEARS MODEL AND SELLS FOR ABOUT $169.00. THE CHEAPER RED SEARS MODEL IS JUNK SO SPEND A LITTLE MORE FOR THE YELLOW ONE SHOWN HERE.
