I replaced the factory pins on my loader with pull type 1" plow pins I picked up at my local tractor store. The pins don't have zerks on them since the loader arm mounts do. If your tractor supply doesn't have pins w/zerks then maybe a local snow plow supply house might. Couldn't you drill and tap the loader arm tubes for zerks after you remove your pins? I replaced my pins to allow me to remove the bucket and put on a plow blade.
