Installation Tips

  • Disconnect the spark plug wire before beginning work to prevent accidental starting.
  • Engage the parking brake and ensure the mower is on a level surface.

  • Ensure the new belt is properly seated within the grooves of all pulleys before reapplying tension.
  • Check the alignment of the pulleys to prevent premature wear on the replacement belt.

FAQ

This belt is designed for various Ultima Series zero-turn mowers, including Cub Cadet ZT1-42 KH, ZT1-46, ZT1-46 KH, ZT1-50 KW, ZT2-54 KW, ZT2-60 KW, and ZT3-60 KW models. It is also compatible with corresponding Craftsman, Troy-Bilt, and MTD zero-turn units that utilize this specific drive system.
This belt replaces OEM part numbers 754-05874 and 954P05874. It also cross-references with part numbers CMXGZAM501089, 490-501-C089, 490-501-F089, and 490-501-Y089.
You should inspect the belt if you notice a loss of ground speed, the mower struggling to climb inclines, or a squealing noise when engaging the drive system. Visible signs of failure include fraying, cracking, glazing on the sidewalls, or stretching that prevents the mower from moving forward or backward effectively.
Before installing the new belt, inspect the idler pulleys and the transmission input pulley for debris, rust, or bearing play. If the pulleys do not spin freely or show signs of excessive wear, they may cause the new belt to fail prematurely. Ensure the deck is clear of grass buildup, which can cause the belt to run hot.
Replacing the transmission belt on these zero-turn mowers is a moderate task. You will need basic hand tools, such as a socket set and a pry bar or belt tensioner tool to release the spring tension. It is recommended to clear the area around the transmission and pulleys thoroughly before starting. Depending on your experience level, expect the process to take approximately 45 to 90 minutes.
