Tom H - and other GearHeads with Manual Lift on Quiet Line tractors (and even other wide frames)- I do see page 30 of the QL Operator Manual has a chart listing options, and shows and "X" (meaning it is an option) on the line for the Float Lockout Pins across all the Quiet Line models, including all the gear drive units. This has to be only when a gear drive has an electric lift. The parts list pages for a 1200, in my TC-157 Parts Catalog, only shows the float lockout pin available under the electric lift parts section. It is not shown in the parts list page for the manual lift section. The way the right hand "Lift Arm Assembly" for the manual lift is set up, if you installed a float lockout pin it wouldn't do anything except be attached to the right arm assembly. The right arm assembly on the manual lift tractor does not have a "Clevis Float Assembly". The Clevis Float Assembly is shown as a part only under the electric lift parts section. The Float Lockout Pin locks the Clevis Float Assembly of an electric lift to the right hand arm assembly. Maybe someone can post the parts diagram of the manual lift and the electric lift used on QL Gear Drive tractors so everyone can see the Clevis Float Assembly that is not used on a Manual Lift assembly. I guess IH should have put a footnote * next to the X in the options table to indicate "only with electric lift".
Frank C - the parts diagram you listed is for hydraulic lifts on hydro tractors.
