I have a 09 L3940 cab HST with BH92 back hoe and LA724 loader. I've got 350 on the meter, and have generally been pleased with tractor. The BH92 has had some issues with the o-rings in the main valves on the BH. Dealer says it's due to a rear remote they connected to a front grapple bucket (pressure surges from the grapple remote, blowing o-rings in the backhoe). They haven't offered a solution yet, other than disconnecting the backhoe (hydraulic lines) when I use the front grapple. That is not convenient as I use both often in the same day. I will make a another post once I have a solution and/or costs to fix. Of the 3940, loader and BH, the back hoe is very strong. Controls (and obviously o-rings) seem to have a design issue.... Hope that helps.
