For what its worth farm equipment is delivered on open flat bed trucks
and the equipment is not tarped to protect it.
The farm equipment is exposed to all the weather, dirt, dust and occasional
pebble or rock that is kicked up by the traffic ahead or alongside the trailer.
Peeling stickers happen due to poor quality glue and or improper installation where
isopropyl alcohol is not used to clean the surface where the sticker will be placed.
As long as it works and you can obtain some degree of service from the seller is all
that matters.
Fortunately the needed repair parts are SAE and standard sizes for roller chain, JIC
hydraulic fittings and the bearings are obtainable locally.
