SP-30 Compost Turner

The ideal entry-level compost turner.

Smaller composting operations or larger farms can benefit from having the Menart SP-30 by reusing or repurposing dairy manure, poultry products, sugar cane waste, or winery waste.

The SP-30 compost turner is the smallest model in the SP Series but packs a lot of value into its small chassis. With 30 years of experience and ongoing improvements, these machines are top of their class and are as efficient as they are effective. It works with your existing tractor and hydraulically folds for simple transport from site to site.

A reliable and efficient machine, the SP-30 can process compost windrows up to 11′ wide and 5′ 6″ tall.

Bottom line: the SP-30 is as cost-effective as it is efficient (VERY!)
