Additionally, I find that during operation the chute tends to vibrate out of position causing me to periodically reach over and rotate it back to the desired position. I looked in the manual for any instruction on adjusting the chute or other advice but there was nothing there except describing how to rotate the chute.
Right - my '90 824 does that too. I'd love to find some friction device to limit free rotation a bit.
And I agree with the previous response - backing up 2-handed would be more awkward and releasing the hand that's on the machine does stop it.
Cheers.
