LEKORD 732-06226 Extension Spring Compatible with CUB Cadet Ultima ZT1 ZT2 Series 50" 54" 60" 46" 42" Mowers (1 Pack)

What It Is

The LEKORD 732-06226 Extension Spring is a replacement tension spring for the mower deck belt system on Cub Cadet Ultima ZT1 and ZT2 zero-turn mowers. It provides the necessary pull to keep the deck drive belt tight and engaged during operation.

Fitment & Compatibility

This spring is designed for Cub Cadet Ultima ZT1 and ZT2 series mowers with 50", 54", 60", 46", and 42" decks. Before buying, verify your mower’s model number (found on the frame or engine shroud) and confirm it uses the OEM part 732-06226. This is an aftermarket replacement, not a genuine Cub Cadet part. Measure the spring’s overall length (uncompressed) and coil diameter—OEM specs are roughly 3.5" long with a 0.5" coil diameter. If your spring is stretched, corroded, or broken, this will match. It will not fit non-Ultima series or older Cub Cadet models without checking your parts diagram.

Key Things to Know

• Quality: Aftermarket spring; reviews are limited (2 ratings), but it’s made from steel with a zinc finish. May be slightly less durable than OEM over time.
• Installation: Easy—remove old spring with pliers, hook new spring into the frame bracket and deck idler arm. No special tools needed. Takes 5–10 minutes.
• Gotcha: Ensure the spring hooks are fully seated; a loose hook can pop off under vibration. If your belt is worn or misaligned, replace it simultaneously.
• Gotcha: This is a single spring pack. If your deck uses two springs (some 54" and 60" models do), you’ll need two.

Should You Buy It

If you need a quick, low-cost fix for a sagging or broken deck belt spring on a Cub Cadet Ultima ZT1 or ZT2, this is a practical choice. It’s easy to install and fits the listed deck sizes, but with only two reviews, it’s best for a temporary or non-critical repair. For a long-term replacement, consider a genuine Cub Cadet spring.
