Scag 451416 YOKE WLMT, CASTE

What It Is

The Scag 451416 YOKE WLMT, CASTE is a welded yoke assembly that connects the caster wheel to the front axle on Scag zero-turn mowers. It allows the front caster to pivot and steer, making it essential for maneuverability and smooth operation on commercial and residential mowers.

Fitment & Compatibility

Before buying, confirm your mower model and deck size. This yoke fits Scag zero-turn models with a 48", 52", 61", or 72" deck, including the Cheetah, Turf Tiger, Wildcat, and V-Ride series (check your serial number range). It is an OEM Scag part (not aftermarket), so it replaces the original directly. Measure the existing yoke’s bolt hole spacing (center to center) and the caster wheel spindle diameter—this yoke uses a 3/4" spindle. If your machine has a different spindle size or offset, it won’t match. Also verify the yoke’s weldment orientation (left vs. right side) as the part may be side-specific.

Key Things to Know

• Quality: OEM Scag steel weldment is durable and resists bending under heavy use, but it can crack if the caster bearings fail or if the mower hits curbs hard.
• Installation difficulty: Moderate. Requires removing the caster wheel, axle bolt, and sometimes the front axle assembly. Have a socket set, breaker bar, and penetrating oil ready for rusted bolts.
• Common gotcha: The caster wheel bearing or spindle may be worn too—replace both at the same time to avoid premature yoke wear. Check the caster fork for cracks.
• Torque spec: Tighten the axle nut to 45-55 ft-lbs (check your manual). Over-tightening can warp the yoke.

Should You Buy It

Buy this if your Scag zero-turn’s front caster is wobbling, binding, or the yoke is visibly bent or cracked. It’s a direct OEM replacement that restores steering precision and prevents further damage to the axle. Avoid if you need a complete caster assembly or if your mower uses a different spindle size—then look for the correct yoke for your model.
