HQPASFY Blade Spindle Kit, Compatible with 42" Deck Cub Cadet ZT1 ZTS1-42, MTD, Troy Bilt, Craftsman Z5200, Mustang Z42 Zero Turn Lawn Mower, Spindles 618-09260, Low Lift Blades 742P05177-L

What It Is

This blade spindle kit is a direct replacement assembly for 42-inch zero-turn mowers, combining the spindle housing, bearings, shaft, and low-lift blades into one ready-to-install unit. It’s designed for residential mowing on Cub Cadet ZT1, ZTS1-42, Troy-Bilt, Craftsman Z5200, and Mustang Z42 models with a 42-inch deck.

Fitment & Compatibility

Before buying, verify three things:

• Deck size – Only fits 42-inch decks. Measure your deck width edge-to-edge.
• Model exact match – Works with Cub Cadet ZT1 (42"), ZTS1-42, Craftsman Z5200, and Mustang Z42. Also fits MTD and Troy-Bilt 42" zero-turn models using spindle 618-09260.
• OEM vs aftermarket – This is an aftermarket kit, not OEM Cub Cadet. It replaces OEM part numbers 618-09260 (spindle) and 742P05177-L (low-lift blades). If your mower uses a different spindle or blade part, it won’t fit.

Check your old spindle’s bolt pattern and shaft diameter (typically 5/8-inch hex) before ordering.

Key Things to Know

• Includes blades – The kit comes with low-lift blades (742P05177-L) pre-mounted on the spindle, saving a separate purchase. Low-lift blades are best for dry, flat lawns—not thick or wet grass.
• Installation difficulty – Moderate. You’ll need a jack, socket set, and torque wrench. Expect 30-60 minutes per spindle. Watch for stripped bolts on older decks.
• Common gotcha – The spindle housing may use different bolt hole spacing than some OEM units. Measure center-to-center hole distance (usually 3.5 inches) on your deck before installing.
• No warranty info – With only one review, long-term reliability is unproven. Inspect bearings for smooth rotation before mounting.

Should You Buy It

If you own a 42-inch Cub Cadet ZT1, ZTS1-42, Craftsman Z5200, or Mustang Z42 and need a complete spindle-and-blade replacement for a worn or damaged assembly, this kit saves time and money over buying OEM parts separately. But with only one review, it’s a gamble for heavy commercial use—stick to OEM if you need guaranteed durability.
