Key features

• Recommended Replacement A worn deck belt can cause blade slipping, uneven cuts, squealing, vibration, reduced blade speed, or sudden failure. Replace your 405143 / 532405143 belt when you notice cracks, frayed edges, glazing, stretching, exposed cords, or loss of tension. Built with high-strength aramid cords and a wear-resistant wrapped cover, this 1/2" x 105.75" belt helps restore stable power transfer and dependable blade performance on compatible 46-inch mower decks.
• Quality Manufacturing Built for demanding mower-deck use, this 405143 replacement belt combines high-strength aramid tensile cords with a durable wrapped fabric cover. The reinforced core helps resist stretching and maintain stable tension, while the outer layer helps protect against abrasion, pulley friction, heat, dust, grass clippings, and repeated bending around pulleys and idlers. Flexible yet tough construction supports smooth engagement, reduced slipping, and steady blade speed.
