Hey all,

My 2010 3320 E-hydro with Cab has recently developed a speed loss in forward gear. On the road the other day and in Hi gear and throttled up to 2k rpm it would get up to about 5 mph. simultaneous to the low speed I got an error code 07. Checked the owner's manual and it is vague that the cruise control switch is held or stuck on. Checked the switch, it is off. Cleared the code, but the forward power is not what it should be (Reverse seems to have full power). On the display there is a tractor icon with a line and arrow under it. I don't recall seeing that before as I have never used the cruise. I'm guessing it is the cruise icon. Hydraulic fluid level is good. I have ordered the TECH/Service manual so hopefully it will have some trouble shooting procedures. In the mean time, Anyone got any suggestions. Thanks!!!

Either your cruise switch has failed in the on position, or the wires have shorted, or the input to the TCU has failed.
Hopefully it's the switch. Get out a multimeter and start checking.
