The Mackeral Water Remover allows you to quickly remove standing water from wet clay courts after a rain. The Mackeral absorbs the water on your court rather than pushing it off the court, causing as little disturbance to the soft court surface as possible. Water is stored in the 7-gallon holding tank within the drum for rapid off-court disposal. The Mackeral is a must-have for courts that tend to puddle in low areas and court owners that need to dry their courts off quickly after a rain. Capacity = 7 gallons. 15" Diameter.
