Well after reading most all of the 129 posts I thought there would be some discussion on how to repair the jerky 3 point issue on the L3400. No such luck.

Can anyone tell me if the 3 point control valve on the L3400 is replaced with a Grand 3 point control valve, would that solve the problem of the jerky 3 point?

I've searched for the Grand valve swap, but cannot find any information.

I just ordered my L3400 Monday and then read about the jerky 3 point later this week.

I can tell you this. My 2005 went back to the dealer right away in 2005 and they ordered a different valve. I don't know if it was a Grand L valve. The dealer never gave me any paper work. They said they found the fix on their web site.

The results of moving the control lever up at a very slow rate were as follows:
Before: the 3PH arms at the ends would jump about one inch at a time.
After: the 3PH arms at the ends would move about 1/4 inch at a time.

This made a huge difference with a mower on the back. It is still not silky smooth like my 1910 is though.

Only the dealers that had replaced the older valves would really know the answer. There was a Rumor/story/B.S. that said the newer models had a "change" / "modification" that no longer allowed the Non-jerky valve to be used anymore.:confused2: :thumbdown: I personally don't believe it...
