UNB Kevlar HD Replacement V-Belt 5/8 x 106" for LANDPRIDE 816-308C (AT2660, FDR1660, FDR2560) - Aramid Cord, Heavy-Duty

The UNB Kevlar HD REPL. Belt is a heavy-duty aftermarket 5/8 x 106" aramid V-belt designed to replace LANDPRIDE 816-308C application belts on 5' finish mowers such as AT2660, FDR1660 and FDR2560.

This aftermarket replacement is built with Kevlar (aramid) cord for strength and heat resistance, sized to the outside circumference of 106 inches and compatible with the PowerDrive 5LK1060 (B103K) specification. It is not an OEM LAND PRIDE part and carries no manufacturer warranty. Colors may vary between black, blue, gray or brown; fit must be confirmed by matching your mower’s OEM part number or by measuring the old belt’s outside circumference.

How do I confirm this belt fits my LANDPRIDE mower?

Confirming fit requires either the OEM part number from your mower or measuring the outside circumference of your existing belt. Check the OEM sticker under the hood or seat of most riding mowers, and verify the number in your user manual.

• Replaceable reference: fits LANDPRIDE 816-308C applications
• Common compatible models: AT2660, FDR1660, FDR2560 (5' finish mowers)
• Match by outside circumference—this belt is 106" total length
• When in doubt, contact seller with your mower serial number

What are the key specifications and materials of this replacement belt?

This is a heavy-duty V-belt with an aramid (Kevlar) tensile cord meant for longer life and higher load resistance than standard fabric cords. Cross-section and length match PowerDrive 5LK1060 / B103K sizing conventions.

• Size: 5/8" cross-section x 106" outside circumference
• Material: Kevlar (aramid) tensile cord for strength and heat resistance
• Type: Heavy-duty V-belt, aftermarket replacement
• Equivalent spec: PowerDrive 5LK1060 (B103K)

If the belt broke, how should I measure to order the correct replacement?

All belts are determined by their outside circumference, so measure the full length of your old belt laid flat to get the correct sizing. If you only have the snapped piece, stretch it out and measure end-to-end to find the outside circumference.

• Measure the belt’s outside circumference in inches for ordering
• Compare measured length to 106" specification for this model
• Check mower pulley adjustment range—some machines require slack adjustment
• Refer to your user manual for pulley types and adjustment instructions

Are there any warranty or compatibility cautions I should know?

This is an aftermarket replacement and does not include any OEM warranty from LAND PRIDE. Some model years or serial number ranges use different belts—verify your mower’s exact OEM part number or contact us for help choosing the correct belt.

• Aftermarket product: no LAND PRIDE manufacturer warranty
• Different serial ranges can require alternate belt versions
• Before purchase, confirm model and OEM number to avoid returns
• Seller can assist if you provide mower model and serial number
