Toro Z Master control arm neutral position return ?

[Cosmoe]

Thanks for the help in advance !!
I just got a zmaster 286E and have a question. The control arms are auto returning to neutral from the reverse position when let go of but not the forward position, they just stay where ever they are and mower keeps moving forward. Like cruise control. Is this normal. Or do I need to check something. I already replaced the dampers. Thanks again.

That sounds like a normal operation to me. You need to reference the operator's manual for clarification.
