I've tried using the search but maybe I'm asking the wrong question. Tractor goes in and out of 4wd easily but sometimes it just drops out of 4wd, usually when you need it most. It works but sometimes you have to hold the lever in place. L3450GST
Definitely in 4wd, front wheels helping and then not.Are you sure its in 4wd after moving the lever? Mine is so hard to get in or out of 4wd that sometimes I can't do it: I have to make sure I'm on soft ground (not pavement or hard dirt), make sure tires are straight, rolling, not under power, etc. It would be nice if mine was easier, but not so easy it pops out, of course.
This seems to be the case. Got the lever to go further and it stayed in gear for the day. ThanksCheck the linkage for wear or bends.
If it doesn't flip all the way over on engagement it can pop back out.
