This week we look at an upgraded concrete pumper chassis from Mack Trucks and a rebar-bender for Bobcat loaders.The Bobcat Rebar Bender is designed to fit a Bob-Tach mount, and it is able to bend rebar up to No. 6 grade to angles up to 200°. A wired remote control allows for the operation of the rebar bender from outside the cab. The rebar bender comes with five mandrels for different sizes of rebar, and an optional bar stop is available for making repeated bends with ease. Bobcat Co.;
