TENGMUJX 61-Inch Deck Mower Blades 6-Pack for Ferris Scag Bad Boy Bobcat — 21 x 2.5 x 0.203 in, 5/8" Hole

TENGMUJX 61-inch deck mower blades are a six-pack of OEM-replacement blades engineered to fit a wide range of 61" zero-turn decks from Ferris, Scag, Bad Boy, Bobcat and similar models.

These blades are made to match the critical mounting and cutting dimensions of common OEM parts so you can restore cutting performance without buying expensive factory blades. Each blade measures 21 inches long, 2-1/2 inches wide and 0.203 inches thick with a 5/8" center hole and 1" air lift, giving you the right fit for many commercial and residential 61" decks. The set replaces numerous OEM numbers and works with an extensive list of mower models, making it a practical swap for worn or damaged blades.

Will these blades fit my 61" zero-turn mower?

Most likely yes, if your machine uses the common 61" deck bolt pattern and center hole size. These blades were designed to be compatible with a broad selection of 61" decks and specific model families from Scag, Ferris, Bad Boy and Bobcat.

• Dimensions: 21" length, 2.5" width, 0.203" thickness
• Center hole: 5/8"; air lift offset: 1"
• Compatible decks: Scag SM-61, STT61 series, SWM-61 variants, Ferris 61", Bad Boy and Bobcat 61" models
• Replaces OEM part numbers including 038-6080-00, 5101755, 5020842 and others

How do these blades affect cutting performance?

Fresh, properly matched blades restore consistent lift and clean cutting action across the deck. Because these blades follow original mounting geometry and thickness, they preserve airflow and deck balance that influence striping, discharge and mulching performance.

• Correct thickness and air lift maintain deck airflow for even clipping transport
• Uniform length and balance reduce vibration and premature spindle wear
• Sharp factory-ready edges improve cut quality and reduce tearing

What should I know about installation and durability?

Installation follows standard blade-change procedures: safely raise the deck, support it, remove blade bolts, swap blades, torque to manufacturer specs and check balance. These blades are manufactured under controlled processes and inspected for fit; however, normal sharpening and periodic replacement are still required based on use.

• Follow your mower manual for safe blade removal and torque values
• Inspect spindles and mounting hardware when replacing blades
• Sharpen or replace blades regularly depending on terrain and frequency

Who is this for: Landscapers, municipal crews and homeowners with 61" zero-turn decks who need an economical, OEM-compatible replacement blade set.
