Kubota F3990 Rear Axle Alignment Issue

[action125]

Looking for some advice on my recently purchased 2017 Kubota F3990. My rear tires seem to be out of alignment. When looking at the mower from behind the rear tires look pigeon toed (but facing out instead of in). Nothing seems to be loose or broken on either side and it seems to drive okay, but it sure doesn't look right. Does anyone know if there is a way to adjust them back to being square? Thanks in advance for your help!
