CUB CADET 734-06305A 5" Deck Wheel RZT-SX46 XT1 XT2 GT54 LT42 LT46 LT50 ST54 Tractors

What It Is

The Cub Cadet 734-06305A is a 5-inch diameter deck wheel designed to support the mower deck on Cub Cadet zero-turn, lawn tractor, and garden tractor models. It prevents scalping and stabilizes the deck during mowing on uneven terrain.

Fitment & Compatibility

Before buying, confirm your mower’s model and deck size. This wheel fits Cub Cadet RZT-SX46, XT1, XT2, GT54, LT42, LT46, LT50, and ST54 tractors with 46-54 inch decks. It is an OEM replacement (part number 734-06305A) and directly replaces the original wheel. Measure the existing wheel’s diameter (must be exactly 5 inches) and verify the axle hole size (typically 1/2 inch). Check that your deck has a single-bolt mounting flange; some older decks may use a different bracket. Not compatible with non-Cub Cadet brands without adapter kits.

Key Things to Buy

• Quality: OEM design ensures exact fit and durability; aftermarket alternatives may vary in plastic hardness and bearing quality.
• Installation: Simple—remove the old wheel by unscrewing the center bolt, then bolt on the new one. No special tools required.
• Common Gotcha: The wheel may rub against the deck if the mounting bracket is bent or if the wheel is overtightened. Leave a small gap (1-2mm) for free rotation.
• Wear Check: Inspect the existing wheel for cracks or flat spots; replacing in pairs (both front or both rear) prevents uneven deck height.

Should You Buy It

Buy this if you own a compatible Cub Cadet tractor listed above and need a direct OEM replacement that matches original specs. It’s a solid choice for maintaining deck leveling and preventing scalping, especially if your current wheel is worn or missing. Skip it if you have a non-Cub Cadet mower or need a different diameter or mounting style.
