955H 60A low serial# lever steer dry clutches and brakes. Front dipstick, just work at it cap likely is likely just rusted to tube. The other tube with breather on cap near it is the Powershift trans filler, the dipstick and filler at the rear by seat is for the Range trans. Use tdto oil in them, The power shift is 2 speed and the range is 2 speed with a neutral to allow for running a inch while not traveling. The range control has a lockout to prevent the lever moving unless the powershift is in neutral. The filter at the back is for the steering and the round cover with a pipe and hose off of it is the steering screen. Trans filter is on the side.
