The engine starts up fine, when I go to press the gas pedal forward or backward it won’t move either direction. Does it have to have time to warm up first before it moves? I also have the blade deck off the tractor to restore it.

Sounds like a safety switch somehow tied in with the deck blade engagement.

my family’s husqvarna had the same issue a while back. we think it was coordinated with an alan wrench looking switch/lever in the back near the hitch, I’m not sure if the hitch is stock but the switch itself is in the back
