For a tidy seeding or planting bed, loosening up the soil and introducing oxygen into it, rotary and reverse rotary hoes are the appropriate tools for the job. Especially when creating green spaces, they prevent soil sealing by loosening the soil, thus allowing surface water to seep in. Nutrients can thus be better stored and released to the lawn plants.
The AT20/21 series side-shiftable rotary hoe has been specially developed for operation with compact and municipal tractors with up to 50 hp. Thanks to the lateral shift option, it is ideal for use in viticulture and orchards. But also in municipal undertakings, in gardening and landscaping, in tree nurseries and in greenhouses, the AT20/21 rotary hoe has proven its worth.
At a glance
Extremely smooth running thanks to spirally arranged blades
In order to achieve smooth running during operation of the hoe, the angled blades are arranged in a spiral around the blade shaft. High convenience is thus achieved with a low power requirement, resulting in convincingly clean milling performance.
Simple operation with maintenance-free chain drive
The blade shaft is driven by a maintenance-free chain in an oil bath. An automatic chain tensioner ensures optimal fitting of the chain. The rear protection hood with integrated levelling rail which can be adjusted via a chain removes any unevenness.
Flexibility on difficult terrain
The lateral displacement of the rotary hoe guarantees maximum flexibility on variable terrain with obstacles. Users in vineyards or orchards will particularly value this flexibility.
