Tracking Adjustment On Hustler Raptor SD.....

If mower veers to left on level ground go CW half turn with front nut on left hydro to speed up that side.
If mower veers to right on level ground go half turn CW with front nut on right hydro too speed up right side.
You can also slow opposite side down to correct tracking but you might lose some speed.
Remember,the mower will never track 100% straight if on a slope unless you steer it straight with controls,thats a skill you need to learn over time.
