I purchased a mid-50's AC D14 with a trip loader on it. I can engage the pin and pull the lever to release the cable and pin. The problem is, when I release the pin, it stays in position and the bucket falls back toward the tractor, even when loaded. The spring looks to be in good shape. I can manually tip the bucket in the dump position and put it back in place. I plan to make note of the loader model and make soon. My question is, does anyone have any thoughts on how to get the trip loader to dump the right direction when the lever is pulled? Should the pin, which appears to be spring loaded near the bucket, go back into place automatically? I'm not real familiar with trip loader buckets, but would like to get this one going for scooping cow manure. I am also working fabricating tines for the bucket right now to better scoop the straw/manure mixture I currently have going on by my barn.
