John Deere LT155 Speed control

My son bought a JD LT155. the speed controls/forward-reverse lever is on the right fender. All the LT155 I saw in the internet have the controls on the right floorboard. We don't know what year the tractor is. Did John Deere have the location of the controls as an option or did they make a middle of the year model change?



Thanks
