It has 3 groups of 6 gears and everything is shifted with buttons instead of levers. The biggest advantage is that it automatically shifts to the next faster gear when shifting groups where the powerquad requires you to move 2 levers to match speeds. Most 60 and TM series tractors are 25 MPH but you might find the odd 18 MPH.
