Husqvarna Tracking/Neutral question

Hey,

I have a Husqvarna LZ 5227. When going full speed it pulls slightly to the left. Also, when i put it in neutral, it seems to want to creep forward still. I've seen some videos on the Toro adjustments that are a screw down by the back wheels. I haven't even looked yet to see if mine have those screws (I will when i get home today). I'm wondering if anyone knows the best way to adjust this on my mower?

I found the tracking adjustments in the manual, which is nice and easy. Still haven't found a neutral adjustment yet.

Find the model numbers on your drives. You will have to get under it. I can then find the drives manual and you can set the return to zero settings.

The tracking adjustment is the neutral adjustment
