Sittler Introduces New 512 Drum Design

The new Sittler 512 windrow turner has an enhanced drum design improving performance. The new larger drum, with shorter, wider, reversible blades, provides even more efficient clean up to the bottom of the windrow, further preventing anaerobic layers from accumulating.

Improved turning enhances the movement of organic matter and increases aeration. With greater turning capacity, the unit is able to tackle more densely packed areas in the windrow. The enhanced turning motion creates a sharper peak with improved CO2/Oxygen flow.

The drum change was a result of positive client feedback from the new efficient 1014 performance. The change allows operators the opportunity to have similar performance to the larger 1014 model with a unit suited to a lesser volume.

The new 512 model has proven performance and client satisfaction. Operators have described the new 512 turner as having an easier turn, with less tractor resistance and engine stress, moving compost more thoroughly, forming a sharper peaked windrow that breaks down more efficiently, making a better quality compost. All Sittler turners are now enamelled with a more abrasion resistant finish and come with a 1 year warranty.


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 ideal CO2/oxygen flow.

Turner folds conveniently for shipping.
