I'm not sure what your definition of "Over-Filling" is, but We ALWAYS heaped up Dad's old JD R spreader as high as we could front-to-back, depending on what the composition of the manure was. Wasn't unusual for there to be more manure ABOVE the sides of the box than was IN the box. The R was similar to the L spreader, just about 10% longer, still ground driven, and in all the years I used that thing it never gave me a second's problem. Only thing I would have liked was a WIDER spreader, like the JD #44 the neighbor I worked for had a pair of. Bet they held twice as much as our R, meaning half as many loads, half the time spent hauling. I heaped them up too, and they were both trouble-free. They were PTO driven.I have an old John Deere L and a New Holland 155. Couple of tips however, As temping as it is to overfill them don't because I've had them jam up or break a cog and unloading by hand is not a pleasant experience.
I have only had the chance to use the spreader three times, today will be the fourth. I'm very pleased with the quality, design and function of the implement. All components are very straight forward, the designers certainly did not over think the machine.Cool...please give us a report/specifics on it when you get a chance. I've seen several ABI videos and have been tempted to buy from them myself. I just haven't heard any feedback from those that had purchased from them....as for as price, build quality, customer satisfaction..etc. They sure have some compelling videos and sounds like they do things right :thumbup1gif:
