Description
V-Belt A-1550 (13×8×1550 mm) for Walk-Behind Tractors and Cultivators
Reinforced A-profile V-belt (marking A-1550, brand Delux) is designed for torque transmission from the drive pulley of a gasoline or diesel engine to the driven pulley of the gearbox in heavy and medium walk-behind tractors, cultivators, and other agricultural machinery. In designs with a belt clutch (tensioner idler pulley), this belt simultaneously serves as a power drive and a friction clutch. Made of high-strength vulcanized rubber with wrapped side edges and a non-stretch polyester cord, it ensures high wear resistance during constant pulley slippage, shock loads on tillers, and operation in dusty conditions.
Key Advantages and Features:
- Oil & Heat Resistant design: A special rubber compound does not swell when exposed to fuel, engine, or transmission oil, and maintains elasticity when heated by friction from the tensioner pulley.
- Anti-Static protection: The outer fabric wrap prevents static charge buildup during high-speed operation in dry, dusty environments.
- Wrapped cord for belt clutch: Wear-resistant rubberized fabric around the wedge perimeter protects the side working surfaces from rapid abrasion against pulley grooves during engagement and disengagement.
- Stable geometry (A profile / 13×8 mm): A top width of 13 mm, a profile height of 8 mm, and a 40° wedge angle ensure a deep, tight fit in standard pulleys without the belt flipping under load.
- Reinforced tensile cord: Prevents critical belt stretching during virgin soil plowing and transporting loads with a trailer.
Compatibility and Application:
Used as a drive belt for the gearbox or for active attachments (rotary mowers, potato diggers, snow blowers, log splitters, concrete mixers) when the 1550 mm length matches:
- Walk-behind tractors and cultivators (belt drive): Neva (MB-1, MB-2), Oka, Kaskad, Tselina, Salyut, Agat, Favorit, Forte, Kentavr, Zubr, Weima, Bulat, DTZ, Motor Sich, Zarya, Dobrynya, Vityaz (belt-driven modifications for A-1550 belt).
- Industrial and construction equipment: Concrete mixers, compressors, circular saws, drilling machines, ventilation units, and grain crushers.
- Interchangeable markings and standards: A-1550 Li (internal length), A-1580 Ld / Lw (datum length), A-1600 La (outer length), A61 (inch marking 1/2" × 61"), GOST 1284.1-89 A-1550.
