Apparatus for filling drainage channels in greens

摘要

Apparatus for filling drainage channels in a green includes a tractor unit (4) with a hopper for gravel (6) at the front and a hopper for sand (8) at the rear. Control unit (10) operates control devices (46) and (76) on the respective hoppers for controlling the release of gravel and sand from the hoppers (6) and (8). The front hopper is vertically movable and is pivotable about a vertical axis so as in use to follow the previously cut drainage channel. Scrapers (14) scrape excess sand into the channel, and compaction of the sand and gravel in the channel is achieved by wheels (12) which run in the channel and a trailing drum-shaped wheel (58) which bridges the channel.
