Elevate deck maintenance with the Aeagle RZT50 Spindle Assembly

Keep your mower cutting cleanly with the Aeagle RZT50 Spindle Assembly. This three‑pack is designed to replace worn spindles on many 50‑inch decks across Cub Cadet, MTD, and related brands. Rather than a rough cut, the spindle supports smooth rotation and consistent blade height, helping you maintain an even mow and reduce downtime between sessions.

Compatibility overview

The RZT50 spindle is crafted to fit a wide range of popular 50‑inch decks and functions as a direct replacement for several part families. This makes it a flexible option for many riding mowers that use a 50‑inch deck.

  • RZT50 and related 50‑inch Cub Cadet deck models in the RZT series
  • LT/LTX series including LT1050, LT1550, LT1554, LTX1050, and LTX1050 KH
  • SLT/LGT series such as SLT1550, SLTX1050, LGT1050 and LGTX1050

In addition, the 918‑04126 and 918‑04125 variants cover i1050 and ZT50 families, while 618‑04126/618‑04125 cover select MTD and Troy‑Bilt units. This broad coverage means a single three‑pack can serve several mower configurations without the need for multiple replacements.

What you get in the 3 pack

  • Three high quality spindles ready for replacement
  • Direct compatibility with a wide range of 50‑inch deck models
  • Replacement parts that align with listed 618‑04126/618‑04125 and 918‑04126/918‑04125 identifiers

Designed for straightforward installation, these spindles offer solid construction and balanced performance. Always inspect mounting hardware and safety guards during installation to ensure proper alignment and operation.
