The Honda 76181-758-L00 Blade V-Belt (LB-73) is a genuine OEM replacement designed for CD4538 and H4013 lawn tractors. Honda supersedes drive belt part numbers at production breaks, so confirm your tractor's serial number against the fitment table before ordering. As a direct Honda OEM component, this belt is manufactured to the same specification as the original, ensuring the blade engagement system operates as intended without modification.
Key Features
- OEM Belt Specification — the LB-73 profile matches the exact length, width, and cross-section Honda engineered into the CD4538 and H4013 blade drive systems, so tension and wrap angle remain within design limits
- Direct OEM Replacement — sourced from Honda's genuine parts programme under part number 76181-758-L00, this belt drops into the existing deck drive layout without alteration
- Fitment — confirmed for CD4538 and H4013 Honda lawn tractors; check your serial number against the compatibility table to ensure this is the correct belt for your production run
- Blade Drive Performance — a belt in good condition transfers power smoothly from the engine to the cutting deck, maintaining consistent blade speed; a worn, cracked, or stretched belt causes slippage, uneven cut quality, and eventual loss of blade drive
The blade V-belt is the flexible power-transmission link between the tractor's engine output and the cutting deck. It runs over drive and driven pulleys, transferring rotational force to spin the blades at the speed needed for a clean, even cut. Over time, heat, load cycles, and normal wear cause the belt to stretch, crack, or glaze — any of these conditions reduces grip on the pulleys, leading to blade slip, missed patches of grass, or a complete loss of cutting function. Replacing a worn belt with the correct Honda OEM part restores full blade engagement and consistent deck performance.
