not being smart, but that was your first mistake.
i wash nothing here for the winter,
water lying in things all winter isnt a good plan imo.
my gear gets blown down and i spray oil mixed with diesel (only reason for that is to thin it down ), but as also said, the trans oil will run through a good sprayer.
the schuts gun is ok, or a paint gun, but id spray about 5-7 ltrs on the baler alone, its a slow job filling a schutz gun canister for that amount.
i wash them when i take them out next year, i dont mind them being slightly dirty over the winter backed into a shed, and the bit of dust and dirt on them helps keep the oil there.
i bought a hudson sprayer off e bay a few years ago, iirc it was about €100 odd.
its the best money i ever spent, use it for loads of things, from disinfectant to oil, thinners, creosote, TFR, shutter releaseand so on.
it came with two nozzles one for thin and one for thicker stuff.
its just a metal one, but its well painted, it never missed a bat yet anyways.
this is it from usa, i dont think i got mine from there, but i cant remember.
