An apparatus for removing roots from bulbs or the like corms, the apparatus comprising:
- a plurality of pairs of rollers for engaging the roots of the bulbs;
- an upper frame supporting said pairs of rollers;
- means for rotating rollers of each said pair in opposite directions for pulling off the roots of the bulbs;
- bulb supporting means positioned below said pairs of rollers, said supporting means being movable between upper and lower positions and being spaced a distance below said rollers in said upper position so as to accommodate a bulb resting upon said supporting means at a position below said rollers;
- means for moving said supporting means downwardly from said upper position to said lower position;
- and,
- means for rapidly moving said support means upwardly towards said upper position so as to throw the bulbs from said support means towards said rollers to enable the roots to be engaged and removed by said rollers.

- said other frame supporting a plurality of pairs of rollers;
- means for rotating said rollers of each said pair in opposite directions;
- said one frame including supporting means forming grooves having sloping walls for supporting the bulbs;
- abutment means for preventing said supporting means from moving towards said pairs of rollers beyond a predetermined upper position, said upper position being so selected that a bulb, resting upon said supporting means in said upper position is accommodated below said rollers;
