Pro-Parts 193214 21546076 Drive Belt for Craftsman Husqvarna LT125 LTH1538 YT120 YT125 Replace 105372 120302X 125907X 193214 1/2"x90"

What It Is

This is a replacement drive belt for select Craftsman and Husqvarna lawn tractors, transferring power from the engine pulley to the transmission. It fits models like the LT125, LTH1538, and YT120/YT125, and is a direct replacement for OEM part numbers 105372, 120302X, 125907X, and 193214.

Fitment & Compatibility

Before buying, confirm your mower’s model number (not just series name) and deck size. This belt is 1/2” wide and 90” long, so measure your old belt or check your owner’s manual for these exact specs. It works on 42” and 46” decks, but not all Craftsman/Husqvarna models—verify compatibility with LT125, LTH1538, YT120, or YT125 specifically. It’s an aftermarket alternative to OEM belts, so expect slight differences in rubber compound but identical dimensions.

Key Things to Know

• Quality: Users report decent durability for the price, but some note it may wear faster than OEM belts under heavy use (e.g., thick grass or frequent mowing).
• Installation: Moderate difficulty—requires removing the deck or belt guard and routing around pulleys. A belt routing diagram (often under the hood or in the manual) is essential.
• Common gotchas: Double-check belt length with a tape measure; “90” can vary by brand. The 1/2” width must match your pulley grooves—too thick or thin causes slipping.
• Warranty: No manufacturer warranty noted; inspect for defects before installation.

Should You Buy It

If you need a budget-friendly replacement for a Craftsman LT125 or Husqvarna YT125 and don’t mind slightly shorter lifespan than OEM, this belt does the job. It’s ideal for occasional or light-duty mowing. For heavy commercial use or critical fit, stick with an OEM belt.
