Hello i have a david bradley super 5.6 garden tractor. It has the locking differential but it will not lock. One wheel spins the other dosent move and it goes no where fast. It used to always work and it drove fine but the other day i was using it to plow snow and i left it overnight and the next day it wouldnt lock. It always has been a little loose, one wheel would spin a little then both would engage and it had plenty of traction . I checked the cable and it seems to be fine. The lever on the handle works and when i move it it moves the part on the transaxle but still only one tire moves. Anyone know about this and how to fix it? Also I was wondering how much it is worth? I have the tractor, the seat trailer, the snowplow, the mowing deck, the dirt plow, 3 sets of discs, and some sort of cultivator thing. It runs pretty good. At the moment everything works except the locking diff and the reverse (i need to get a belt for it).

I've never worked on the locking differential, but if I had to guess I'd say something got wet & froze. Try warming it up, maybe?

It's possible that the roll pin that connects the shift fork to the shaft going into the trans-axle could be sheared off. Also, there are two small springs that hold the the shift fork in the locked position. If these are broken it causes it to disengage, especially if the tractor is leaned heavily to right.

We would all like to see some pics.

My first guess was water too, but maybe something froze and while trying to get it to work, a weak spring or pin has given up.
If mine, I would warm it up as much as I could without direct flame and see if it works correctly then. If so, drain oil and maybe even flush with kerosene before refilling. Keep in mind, it will take a long time to get the heat all the way thru. Dad used to keep one of the old tractors limber by covering with an old blanket and putting a 100 watt lightbulb under there... Won't work with the new cfl or led lamps tho
