200 Hydraulic Level

I have not got the brakes fixed yet on the 200 yet. I had a leaking lift cylinder that i replaced, as a result i was low on fluid. Its a 22 quart fill if i remember right, and i have put 5 gals in since replacing . My issue is that when i do my pre flight check i cant seem to find the fluid on the dipstick. I add fluid every time, but it is pretty clear oil. So where could it be going, or have i just not filled it enough? Its not getting into the engine oil pan because its level doesn't change. Haven't noticed any issues with steering, the power director might grab a bit more in neutral but that seems to go away when it warms up, and when i checked the left hand brake has oil in tis housing. The only other thing i can think about is that its leaking out of the implements. Chisel plow has a small leak, and the hay mower had bad seals in it so it squirted out the smallest amount of oil. Any ideas on possible issues or am i just being paranoid?

If hydraulic fluid is coming out in  the brakes, It's transferring into the rear end through the seal on the PTO shaft.
