Help !! Front wheel drive not engaging

[MickInOhio]

Hi folks , owner of a 2019 CK3510 . My issues are as follows ,

1. Front wheel drive will not engage . The shifter pulls smoothly but no front wheel engagement .

2. Locked shifter for posi- traction on rear wheels .

I gave both a visual look but I'm like Stevie wonder ..... With tools .

Any and all tips and tricks are appreciated ! Thanks in advance and no , i don't have a manual available . i did change out the gear oil !

Can you give us some more details? Like how do you know that the front isn’t engaging, how many hours on the tractor, why did you change the gear oil….etc.
Below is some related reading, although a different tractor. Keep us posted.
