Generac Belt OEM #407471

Keep your Generac DR CRT rear tine tiller operating in reverse with the genuine OEM Power-Rated Drive Belt (Part #407471). Officially designated BELT-PWR RTD 3LXP755 CRT TILLER (REV), this factory-original belt is the dedicated reverse drive power transmission belt for the CRT (Counter-Rotating Tine) tiller platform — transferring engine power to the tine drive system specifically when the reverse function is engaged.

This is a Power-Rated (PWR RTD) belt, meaning it is manufactured to a higher load capacity than standard V-belts — built to handle the full torque demands of a tiller working through hard, compacted, or rocky soil in reverse. When this belt wears, stretches, cracks, or breaks, reverse tine engagement becomes impossible, making it difficult or unsafe to back the tiller out of tight rows, hard ground, or established garden beds.

Also Known As:

• Belt-Pwr RTD 3LXP755 CRT Tiller Rev
• Belt Drive Pwr Rtd 3LXP755 CRT DR Tiller
• DR Power Part 407471

Belt Specifications:

• Belt Type: Power-Rated Drive Belt (PWR RTD)
• Belt Size: 3LXP755
• Application: CRT Tiller — Reverse Drive (REV)

Key Features:

• Genuine OEM Power-Rated Drive Belt — Manufactured to exact factory specifications for the CRT Tiller’s reverse drive system, ensuring correct length, width, cross-section, and power rating for safe, reliable reverse tine engagement
• Power-Rated (PWR RTD) Construction — Unlike standard V-belts, Power-Rated belts are engineered to carry significantly higher loads, resisting the heat, tension, and shock loading generated when counter-rotating tines work through dense, compacted soil
• Dedicated Reverse Drive Function — This belt specifically drives the tines in reverse (REV) rotation — the counter-rotating direction that makes the CRT tiller so effective at aggressive soil breaking, weed burial, and working in established beds
• Engineered to Withstand Heavy Use — Designed to withstand the rigors of heavy tilling use while providing optimal power transfer and durability, keeping the tiller running smoothly and efficiently season after season
• Exact Size 3LXP755 — The “3L” designates a fractional-horsepower belt cross-section; “XP” indicates extra-power / cogged construction for improved flex and heat dissipation; “755” denotes the effective length — all critical to correct pulley engagement and belt life
• Direct-Fit OEM Replacement — Manufactured to the same dimensional tolerances as the original for drop-in installation without modification

Most Common Reasons to Replace:

• Belt slipping, squealing, or failing to engage reverse tines fully
• Visible cracking, fraying, glazing, or missing cog sections on the belt
• Belt has snapped or come off the pulleys during operation
• Reduced or inconsistent reverse tine power
• Scheduled replacement as part of seasonal tiller maintenance

Why Genuine OEM Belts Matter on Tillers: Tiller drive belts operate under some of the most demanding conditions in outdoor power equipment — continuous high-torque loads, abrupt engagement and disengagement, and exposure to soil dust, heat, and vibration. A belt that differs in cross-section dimensions, effective length, or power rating from the original will slip under load, wear pulleys unevenly, run hot, and fail prematurely. The 3LXP755 size designation is precise — even a belt that appears similar but differs by a few millimeters in length or width will not track correctly on the original pulleys, reducing tine engagement force and belt life. Only a genuine Generac OEM belt restores the factory-spec power transmission performance your CRT tiller was designed to deliver.
