Abstract
The modular drive wheel for log processors includes a tubular midsection sandwiched between a pair of annular rings mounted concentrically on opposite ends of the midsection. The midsection has a resilient outer surface extending around the midsection. The pair of annular rings each have a radially spaced apart array of notches therearound. The notches in the radially spaced apart arrays of notches are sized to snugly receive in releasable locking engagement therein links on opposite ends of chain segments extending between the pair of annular rings. The drive wheel further includes means mounted between the pair of annular rings for selectively forcing apart the pair of annular rings along a longitudinal axis of symmetry of the midsection.
