White GT-1855 Mower, Lawn and Garden Tractor Category

Original Model: Briggs Various

There were two different engines that these tractors came with and they will not interchange. The Opposed twin is no longer available. The V-twin 20 horse power is currently out of stock. We have the 18 horse power but if you use the 356447-3079 engine and you drive of the flywheel side of the engine, you will have to use your flywheel and shroud of the old engine as the 356447 series engine is about 1-3/8" wider than the 351447 series. You may have to use parts of the old engine for this to work for you. The wiring may be different but you can use your alternator and regulator of the old engine.
