OJB manure spreaders are designed, tested and fine-tuned on our own farm. They are designed to handle a super wide range of solid to semi-solid manure types. With an OJB spreader you can spread cattle manure, cow pack, poultry manure, compost and sand-laden manure. The fully integrated running gear and box design has some unique advantages. All models have a high volume and payload with a relatively low loading height. All spreaders have a wide wheel base which gives enormous stability.
