Toro Low Flow Blade | 24.5" | GrandStand / Z Master | 72" - 96" - 144" Decks | 140-4851

Toro 24.5 Inch OEM Low Flow blade. Low Flow mower blades have slightly curved ends that keep air Flow to a minimum. The lack of suction allows cut grass to exit the mower while keeping dust and debris levels down. Toro Low Flow mower blades cause less engine strain than Hi-Flow blades. This Toro blade has multiple applications. Be sure to verify model and serial number to ensure the correct part.

Hole Size: 15/16 inch (approximately 0.9375") center hole diameter. This blade typically requires a spindle shaft with a Hex Insert for proper mounting.
Blades Needed: The number of blades required depends on the deck size:
72-inch Deck: 3 blades.
96-inch Deck: 4 blades.
144-inch Deck: 6 blades.
Note: For 72-inch rear discharge models, only one 140-4851 blade is used (on the right), paired with two 140-1239 blades.
Mower Deck Fit: Fits 72-inch, 96-inch, and 144-inch side and rear discharge decks on Toro GrandStand and Z Master series mowers.
Blade Dimensions:
Length: 24.5 inches.
Width: 2.5 inches.
Thickness: 0.204 inches.
Blade Type: Low-Flow (Rotary) blade. It features slightly curved ends to minimize airflow and suction, making it ideal for dry, sandy, or dusty terrain where reduced debris blowout is desired.

Model Compatibility
The 140-4851 low-flow blade is compatible with various Toro Grandstand and Z Master series mowers with 72", 96", and 144" cutting decks. These product lines span models produced both before and after 2020. 
Current Models: The part is compatible with models in the current 2000 and 4000 series, although these current series do not have the 72", 96", and 144" deck size options that the blade fits (it fits the decks, but those decks aren't options on the current 2000/4000 models).
Older/Varied Models: It is also compatible with specific model numbers like 72096, 72076, 72947, and many others, which were released across a range of years. 
Important Fitment Note
Due to potential overlaps in models and serial numbers, it is critical to verify the specific setup of your mower's blade arbor assembly. 
The Toro part number 140-4851 requires the shaft/blade arbor assembly to have a hex insert.
If your mower has an external octagon or round flat shaft, you would need a different part number, such as 105-7712-03, instead.
