Excellent quality. For the past 50+ years we have used a 110 bushel New Idea ground driven spreader, designed exactly like this spreader. Exactly the same beater configuration and the same drive ratios. We have many skeleton dinosaur versions of the New Idea that have been used for parts to keep one running. Last year we purchased this spreader. I can say without a doubt that this is the best money I have ever spent on farm equipment. Quality everything. Heavy duty and I would easily have spent much more to get this quality. About the only thing I did was replace many of the grease fittings with angled one so that I could easily get to all of them. I also added a small piece of steel to cover the very back gear on the distributer bar better. We use a 60 year old Farmall 200 (25hp new) and it drives this loaded spreader like a dream. We absolutely must have the top beater bars for our manure, and none of the other brand spreaders, in this class, provided that.
