Yes, all that is normal for that tractor. Typical six speed, non multi-power, live PTO, 165. All similar Massey models had straight cut transmission gears, and yes, they are a bit noisy. The hydraulic pump and PTO are both driven off the center disc of a two stage clutch, so that disc must be engaged for either of them to operate (clutch pedal half way up). Might take some getting used to, but that's the way they made it.
It's a simple, dependable tractor, but it has a few drawbacks. For one, it's light on hydraulics. If you need or plan to add anything that requires any hydraulics other than the three point, the options are limited, and not very convenient.
