Slurry flushing

Slurry needs to be removed from a housing system either by manual tractor scraping or by some form of automatic system. The automatic systems either involve scrapers or, alternatively, a flush wash system.

Automatic scrapers

Automatic scrapers tend to be hydraulic, where the scraper blade sits on a saddle which moves around 1m every time the track is pushed forward by the ram. This system requires a track to be mounted on the scrape passage which can be problematic if manual scraping is required. The hydraulic scrapers also require the track to be kept clean in the summer to prevent a build-up of slurry. The slurry layer on the track will cause the saddle to disengage from the track. The track is also not particularly kind to cow's feet.
