Toro ZT Timesaver 2500 won't move

[fiddlearound]

As per title, my Toro won't move, starts and runs fine. I was mowing and it just stopped moving. Mower deck still runs.
Any ideas? Thanks.

Simple things first.
Check that the drive belt is sill there and sitting properly on all pulleys.
Check the tension pulley is spinning free and the spring is pulling the belt tight

Check the bypass valves have not accidentially turned onto bypass.

Thanks, I will check all of those factors.
