LEYURISE mower deck belt for Kubota RCK60 & BX tractors — 1.18" x 120" 2-band, aramid-core heat-resistant

LEYURISE's MID-Mower Deck 2-band belt is a heavy-duty 1.18" x 120" replacement belt engineered to restore reliable power transfer on compatible Kubota mower decks and compact tractors.

This replacement belt fits a wide range of Kubota RCK60 mower decks and many BX/B-series compact tractors, matching OEM part numbers such as K5763-34710, K5371-34710 and K5763-34712. Built from thickened, heat- and corrosion-resistant rubber with aramid core cords and a grooved profile, the belt is made to maintain stable engagement with deck pulleys, dissipate heat, and resist deformation under tension. The following details help you confirm fitment, understand performance features, and walk through quick deck inspection steps that help maximize belt life.

How do I confirm this belt fits my Kubota mower deck?

Verify compatibility by checking your deck model and existing part number. This belt is intended for RCK60 series decks (including several RCK60B and RCK60D variants) and many BX and B-series tractors that use a 1.18" x 120" mid-mower deck belt.

• Compare your current belt length (1.18" x 120") and band count (2-band).
• Match OEM references: K5763-34710, K5371-34710, K5763-34712 and related numbers.
• Consult your mower deck model (RCK60 family) or tractor model list for fitment.

What performance advantages does the LEYURISE belt offer?

The belt combines a thickened rubber jacket with high-elastic aramid core wires and a grooved design to improve engagement, longevity, and heat management. These construction choices reduce the chance of permanent stretching while maintaining steady power transmission under load.

• Thickened rubber for heat and corrosion resistance during heavy use.
• Aramid core cords provide high elasticity and impact resistance.
• Grooved profile accelerates air cooling and ensures accurate pulley engagement.

How should I inspect the deck and pulleys before installing the belt?

A quick inspection prevents premature belt wear and slipping. Look for bearing drag, pulley damage, debris in grooves and weakened springs—addressing these issues before installation preserves belt life and cutter performance.

• Rotate pulleys by hand; replace if bearings are rough or noisy.
• Remove rust, burrs or sharp edges to avoid cutting the belt.
• Clear grime and vegetation from pulley grooves so the belt seats properly.
• Test deck tension springs; weak springs can cause slipping and heat buildup.

What installation tips improve lifespan and reliability?

Install with correct routing and tension, and avoid forcing the belt over damaged pulleys. Allow new belts a short break-in period under light load to seat the cords and reduce early stretching.

• Follow your mower’s routing diagram and torque specs for idlers and tensioners.
• Replace worn pulleys, clips or fasteners when fitting a new belt.
• Run the deck briefly without heavy cutting to let the belt bed in.

Who is this for: This replacement belt is for owners and technicians of Kubota RCK60 mower decks and compatible BX/B-series compact tractors who need a direct-fit, robust mid-mower deck belt.
