I believe 90 to be correct but took some ones word for it and never looked any further into it. I will check on that...
I use it on fairly steep hill but never really pushed taking it horizontal on the hills. It turns on a dime which is nice in areas that are semi wooded but grass areas.
Runs well. Sad to see it go but I am no longer cutting hay and could better use the money on something else.
Would love know to what you plan to use it for if you buy it
