Starting with PTO Engaged

[Dave M7040]

Forgive me if this has been covered elsewhere.

My Kubota L3010 HST is doing something that seems different to me. Yesterday I tried to restart the tractor (thought I had the clutch pushed in) and it was dead. I noticed that the PTO lever was engaged, so I disengaged it and the tractor started normally.

My question is this: Should the tractor start if the PTO lever is engaged and the clutch is pushed in?

You learned the trick to minimize theft all by yourself

The Kubota keys, unlike a car or truck, are not unique to your tractor. Your key will work on most in your series if not more.

Owners leaving their tractor unprotected, often leave the pto engaged, when they walk away. In the dark, or with some kid, this is enough to prevent it from starting for the thief.

Ebay have a set of keys that will start almost every tractor on the market, a thiefs delight for about $50, when I bought the BX the salesman said all keys were individual, I had no reason not to believe him until they came and took it away for a warranty problem and used their own key to move it.

Why would you want to be able to start the machine in a dangerous configuration of the pro or drivetrain in operation .

Why would you want to start the machine in the dangerous configuration of spinning shafts and movement .

A bit different scenario, but:
I couldn't find the one I'm thinking of, but there's several videos out there of people "pull starting" their tractors by wrapping a strap around the pto shaft of the attachment (rotary mower, etc..) and using the family sedan to pull it, thus starting the tractor.
Can this be done on hydros? PTO is direct drive right?
Why not just jump the tractor battery with the sedan? - Useful if the starter is bad I suppose.
Useful method if the attachment or FEL was lowered to the ground and you can't easily roll /pull/pop start tractor, or a hydro.
I wonder if leverage/gearing allows one to grab and spin mower blade to start like starting a propeller plane? Probably not.

So you can start when PTO is engaged, you just can't use the starter...to start.

The safety interlocks typically prevent the starter from engaging. So if you are pull starting or the like, just turning the key to on should open up the fuel shutoff solenoid.

You can't "pull start" a HST by rotating tires. But you should be able to do the PTO tricks as long as the PTO was manually engaged, not electrically or hydraulically.

Typically 540rpm PTO speed is around 2000-2500rpm engine speed. So the PTO is at a mechanical disadvantage to the engine.
