Another way could be using the motor for rotation, then adding a small cylinder that would push a pin through a hole on a round plate full of holes. This cylinder would lock the blade in position.
A crossover relief valve could be added to the motor in case you forgot to lock the blade, so it would just let go before causing any damage.
If you're limited by number of remotes, a diverter valve could be used to switch the control valve between motor and cylinder.
This way does require "finding" the right position so the pins goes in the hole but still better than leaving the tractor all the time to adjust the blade in my opinion.
Also, I say small cylinder, as in small diameter, so it doesn't have enough force to bend stuff if the pin is not aligned with the hole.
