Turf aerating apparatus with resilient handle mount

摘要

A walk-behind turf aerating apparatus includes two pairs of tine arm assemblies, each assembly having a pair of vertically reciprocating tine arms for driving coring tines into the turf. A tine arm return mechanism includes a gear box for each pair of tine arms, the lower ends of the tine arms being connected to cranks extending from the gear box to reposition the tine arms prior to ground engagement. Stops are provided to limit the tine arm travel. A spring-loaded lifting mechanism permits manual shifting of the tine arm mechanism from a lowered ground-engaging position to a raised transport position. A belt drive with clutch and reduction drive for the wheels also drives the tine arm mechanism with automatic disengagement when the wheels are in the transport position. A handle assembly is connected to the apparatus frame through a pivotal connection including vibration damping elements for minimizing transmittal of vibrations, particularly in the vertical plane, to the handle.
