MF 65 power steering reservoir and air inlet reservoir(?)

[CTWright]

I found a pdf of a diesel mf65 online. On page 38 it says the reservoir holds 3.5 pints of Type A ATF. On page 3 it shows the reservoir in front of the fuel tank and behind the air filter. My tractor doesn't have this reservoir. It just has a plug on the top of the pump. Anybody else have the reservoir? I also have a plastic square reservoir of some type that is connected via a hose to the air inlet hose on the right side. This reseveoir was back by the battery but I don't see it in any picture in the owners manual. Is it an oil blow by reservoir of some type? Where is it supposed to be mounted?
