The loader was quite a machine, not JD but I don't remember the make.
Trip dump and you had to backup while lowering bucket to reset it.
It worked well with systems here as most manure was piled outside with a litter carrier through the year although part of barn was converted for loose housing and loader just snuck in for height.
That resulted in father injuring his neck when he didn't duck one time.
Laid him up for most of a year so I got to experience much farming as a teenager before I could even legally drive.
