One example provides a low-profile grinding machine for sharpening a cylindrical cutting reel of a mower unit. The grinding machine includes a grinding wheel driveable in a reciprocating fashion along a grinding axis, and a grinding platform. The grinding platform houses the grinding wheel and includes a bottom side to sit on a ground surface and an opposing upper side. The upper side includes a ramp portion sloping upwardly from the ground surface to enable the mower unit to be pushed or driven from the ground surface onto the upper surface to position the cylindrical cutting reel over the grinding wheel for sharpening, the lawn mower positioned with a rotational axis of the cylindrical cutting reel extending along the grinding axis.
