The Difference Between Belt Driven Machine And Gear Driven Machine

     The 170 belt driven machine is different from the 171 and 186 gear driven machine 171 and 186 are rotated by gears,and 170 is driven by the chain-belt.There will be a belt running outside the belt driven machine,so there will be a protective cover outside.Wheels with two slots can be covered with a full or half wrapped protective cover.And then the three-slot is so big that you can only use a half-pack of protective covers.
