I have an old IH rake similar to that as a back up. That one may be new enough, that like my IH rake, will also ted hay, flipping the lever to engage the drive, in another notch, 180º opposite in the raking position.
If you have any Amish in the area, they maybe interested in that horse drawn mower, if you have no use for it. A lot of people looking for them also for yard art.
That manure spreader doesn't look to be in that bad of shape, unless there is something I can't see. Most, the sheet metal will rust out in the beater area. More than likely, the apron chain is broken. Lots of people out there looking for fix'er upper stuff like that. Been there myself..!!
