Sittler Windrow Turner Model #509, shown above, is ideal for small to med farm, municipal and industrial composting.

The Sittler 509 compost windrow turner is reliable, efficient, economical, low-maintenance, and long-lasting. Extra-hardened, replaceable steel blades are uniquely positioned on the drum to allow for complete blending right to the base of the windrow. Material from the outside is brought inward and from the bottom to the top forming a peak position, allowing the windrow to have a chimney effect for CO2/oxygen flow.

The drum is designed to aerate all the compost and create a peaked windrow allowing for maximum air flow.You can clearly see the drum reflection as the compost is turned on the ceiling of the tunnel.

Turner folds conveniently for shipping.

Rectangular box for connector-3/8x6 in front, 1/4x12 on side enclosed for protection gives more strength and stability. Low swing cylinder. 2-piece rubber flap, one on each side contain compost. 2 front scrapers keep the windrow uniform.

Hydraulics allow the tractor to fit snug against the windrow.


The blade has been redesigned to create more durability. The blades can be rotated allowing for longer life span.
