Mikeiwest: >>Creeper Gear does exist. If a creeper gear exists it should mentioned in the operators manual and have parts in the parts manual to impement it. Below are pointers to the owners and parts manual for the Simplicity Pro P1628E 1695305. I could not find any mention of it in the owners manual or parts to get the gears to invoke a low speed function other than the friction disk movement.

Other than marketing literature where does it exist? What factory model number machines have this feature?
