Yesterday while using my YM1700 doing some bush hogging, I was going up a steep place and it hit some soft sand on one side. As the right wheel was spinning I thought that was a good place to finally try out my Trans Lock. So I stopped and pushed the lock down. Worked just great, came right on up out of it. But when I let off of it, I thought it was suppose to come back up, by its self. But it didn't, I had to lift it up with my heel, to get it it back up. Is this the way they are suppose to work, or do I have a problem?
