The PTO usually has a clutch that has to be engaged so that you can select the PTO rotation setting. I had a problem like that on my tractor and all it needed was a little adjustment on the PTO clutch lever, so it could disengage the PTO gearbox properly.

The engine needs air, so be sure the air filter is clean. If it is not, replace it.
The engine needs spark. Replace the spark plug and be sure that the battery has a complete charge.
The engine needs good fuel so be sure the gas is newly purchased, not gas that has been sitting around for months.

Check there is adequate fuel to supply engine. Check there is no damage to fuel lines and that the fuel filter is not plugged. Yours is a Yanmar diesel engine withe an autobleed feature which is supposed to bleed the air out of the system automatically. It may incorporate an electric fuel pump also, but some don't. You can prime the fuel system to the injection pump with the manual lift pump if it is equipped with it. After establishing fuel to the injection pump, loosen the nuts that hold the fuel lines onto the injectors approximately1 1/2 turns. Turn the engine over until you see fuel coming from the injector nuts. Tighten the nuts to 24 inch/lbs of torque, start the engine and run at 1/3 throttle untill it runs smooth.

On some of the 4020's the starter brush dust will pile up and cause a partial short circuit. This will drain the batteries after a couple days. Short of removing the starter I don't know if there is a way to jar or blow it away.
