Toro 140 4857 OEM Low Lift blades have a subtle curve at the end to minimize air flow. This reduced suction allows for a cleaner mowing experience, with less dust and debris for a lower liability. Compared to Hi-Flow blades, Toro's Low Flow blades cause less strain on the engine. For dryer sandier conditions and lighter grass types, the Toro OEM 140 4857 LO-FLOW Mower Blade is the preferred choice. This Mower Deck Blade was made to OEM Specifications to fit Toro Grandstand and ZMaster 3000, 4000, 5000 and 7000 series with a 52 in. Deck.

NOTE: Due to a Serial Number brake that could overlap Models, The Toro 140-4857 does require the Shaft/Blade Arbor Assembly to have a Hex Insert. Refer to the image above for an accurate Comparision. If you have an External Octogen or Round Flat shaft refer to part number 105-7795-03. Some Grandstand Model with the 36" Mower Decks will use the same Blade as the 52" Mower Decks, However Models containing the newer Hex Insert Shaft/Blade Arbor will not use the same blades between the 36" and 52" Mower Decks.
