LT1000 mowing deck pulley brakes

[Cusser]

I have a Sears lawn tractor LT1000, Model 917.275371 serial number 013105A002361. I would just like to confirm/further my understanding. Question: when one moves the mowing belt engagement lever even with the engine off, should the pulley brakes move away from the pulleys? Thanks.

Of course, They are brakes.

Thanks. I should be getting this lawn tractor up on the tractor jack next week.
