SCAG Pulley, 5.73 Od - Taper Bore Part # 483284

What It Is

This is an OEM SCAG taper-bore pulley, 5.73 inches in outer diameter, designed to drive mower blades or belt routing on SCAG commercial zero-turn mowers. It’s a direct replacement for the original part on select SCAG decks.

Fitment & Compatibility

Before buying, confirm your machine’s deck model and serial number. This pulley (part #483284) fits SCAG decks including the 48" (SD), 52" (S/N 3C0200001 and above), 61" (S/N 3C0200001 and above), and 72" (S/N 3C0200001 and above) on Cheetah, Patriot, Tiger Cat, Turf Tiger, and V-Ride models. It’s not universal—check your existing pulley’s OD (5.73”) and taper bore size. The taper bore requires a specific bushing (sold separately) for shaft fitment. If your deck uses a straight bore pulley, this won’t work. Cross-reference with your owner’s manual or SCAG’s online parts diagram to verify.

Key Things to Know

• Quality: OEM SCAG part, built for heavy commercial use with durable cast iron construction and sealed bearings. Outlasts most aftermarket alternatives.
• Installation difficulty: Moderate. You’ll need a puller to remove the old pulley and a torque wrench to tighten the taper-bore bushing bolts to spec (typically 20-25 ft-lbs). No special tools beyond that.
• Common gotcha: The taper bore requires proper alignment and bushing seating; overtightening can warp the bore. Also, check belt condition—worn belts can damage a new pulley quickly.
• Noise: Some users report a slight whine at high RPM if the bushing isn’t seated perfectly—double-check alignment during install.

Should You Buy It

Buy this if you need a direct OEM replacement for a SCAG commercial mower deck with a 5.73” taper-bore pulley, especially if you value durability and exact fit over saving a few dollars on aftermarket parts. It’s ideal for pros who can’t afford downtime from a misaligned or failing pulley. Skip it if your deck uses a straight bore or if you’re on a tight budget—aftermarket options exist but may not match OEM longevity.
