Probably the worst built machine I have ever came across. I want either a well built replacement or to return this disaster of a hay elevator. The Problems: 1) A blind monkey must have cut the pieces and done the welding as the two parts of the track did not line up at all causing the hay carriers to hit and get stuck. 2) Was missing chain tensioner on the inside for the chain. The chain is very loose and would require a round block to push down/up going from the larger wheel to the smaller wheel. The bottom one was missing so after it moved for a few turns it came off the track causing the motor to seize. It needed to be backed off and put back into place to move again. 3) After a short time running probably from the stress when the chain got stuck the chain came apart! while i was able to place it back together the pieces are not snug as they should be, and I know this will keep happening. 4) The rate of speed is too fast. If the prongs could catch the bales it brings them up quickly but what actually happens is they dont have time to dig in and just kick off while traveling up. Even had to raise the bottom up quite a bit just so I could get my bales in. With that you would have to put the same bale on about 6 times to get it to stick on. Extremely annoying, and tiresome when bales are 50lb each and you are working with 125+. You need to make this right!!!
