Is it necessary to depress the clutch pedal before engaging the the 4WD on a L3400 HST? Second question is can you take the tractor in or out of 4WD while moving? I always stopped with my BX but was not sure.
Thanks
First question, NO you dont need to press the clutch, unless you are spinning the wheels.
Second, it is probabally advised in the manual to STOP before engaging and disengaging, but you dont have to. Since you arent changing gearing, just make sure you arent spinning when you engage. But if you are just driving/coasting along and the front wheels and back wheels are turning the same speed, no harm will be caused.
firefighter jim said:WRONG......You must be completely stopped and you must depress the clutch when shifting from 2 to 4 wheel drive and from 4 to 2 wheel drive. You might be referring to the differential lock in which case clutch does not have to be used nor does tractor have to be stopped.
