Ya know.....one of the older L245's I work on had this issue (the owner called and said it was stuck.....panicked needing help)......
Well.....
It turned out that the rear 3-point attachment hydraulic system had been positioned in full up, and this had locked up the hydraulics for some reason.....yep, I moved the lever down about 1/2 way, and presto.....he thought I was a genius.
Now.....for one-upping that one: (wish I could have been consulted on this one!!!!!)
My son's girlfriends parents have a older Ford Ranger.
They said it was going slow, and the motor is "sounding weird"
Took it to the dealership
PAID $200 to find out.........wait for it.........
It was in 4 low
