1450 mower

I can't keep my mower attached to the mule drive or carrier it comes unhooked almost immediatley when I start mowing, is the bail supposed to be up or down to lock it in?

Jim,
Bail should be up to lock the subframe in place, down to remove or install it. The bail is normally spring loaded to the up or locked position, but if the springs are broken or missing, you may need to secure the bail in the up position someway.

Thanks Paul, the springs must be broken I will wire it up for now
