I was also wondering if the Ariens, after you start the auger and the drive system can you take one hand off the levers to change the controls, say to turn the chute. Will it still continue to go forward and blow snow.
All Ariens models 624 and larger have the control interlock you're referring to.
The 1027LE doesn't have a differential, only a remote locking and unlocking axle (locks and unlocks the left wheel for easier turning).
There is no need for a differential lockout on the 1130DLE because in locks and unlocks automatically as needed. Traction like a solid axle and the maneuverability of a differential at all times.
