A rotary cutter lifting apparatus comprising:
- a table plate having an upper surface, a lower surface and an opening extending from the upper surface to the lower surface;
- a carriage disposed beneath the table plate and adapted for supporting the rotary cutter;
- an adjustment mechanism positioned entirely below the table plate upper surface and operable through the opening;
- a first gear of the adjustment mechanism having a splined outer surface;
- and
- a second gear of the adjustment mechanism having a splined outer surface which rotationally engages the splined outer surface of the first gear;
- wherein rotation of the first gear causes rotation of the second gear;
- which causes vertical movement of the carriage relative to the table plate.
