This ski slope snow groomer was originally made under the Thiokol name until the company was sold to John Delorean.  Later when the Delorean name was tarnished, it was changed to Logan Machine Works.  The machines were 300 hp and turbocharged.   Most were full hydraulic drive and used our Torque Hub planetary wheel drives.  A few were mechanical using a patented steering differential.  Fairfield designed and made all  of the drive components.
