Fitment note: These are supplier-provided model-family examples. The belt fits only the compatible mower-deck and belt-routing configurations using M154958 or M110313.

John Deere X320 and X324 Fitment

On select John Deere X320 and X324 tractors equipped with a 48X mower deck with rotatable gauge wheels, the mower deck uses a two-belt system:

• M154897: Primary PTO-clutch-to-deck belt
• M154958: Secondary spindle-drive belt

This listing is for the M154958 secondary belt only. It does not include the separate M154897 primary belt.

Do not use M154958 on the X320 or X324 48X deck configuration that calls for the single long M155368 belt. Confirm the gauge-wheel configuration and original belt number before ordering.

John Deere X300, X304, X310, X340 and X360 Note

The supplier associates M154958 with select mower-deck configurations across these X300 Series models. These tractors were offered with multiple deck sizes and belt-routing arrangements.

Do not select this belt from the tractor model alone. Confirm that the original secondary deck belt is marked M154958 or M110313.

John Deere X500 Series Note

The supplier also associates this belt path with select X500, X520, X530, X534, X540, and X590 mower-deck configurations.

Not every X500 Series deck uses M154958. Match the installed mower deck, original belt number, and two-belt routing system before ordering.

Primary Belt vs. Secondary Belt

Many compatible John Deere 48-inch mower decks use two separate belts:

• The primary belt transfers power from the engine-mounted PTO clutch to the mower deck.
• The secondary belt routes through the mower-deck spindle and idler pulleys.

M154958 and M110313 are commonly used in the secondary spindle-drive position. The primary belt is a separate part and is not included with this listing.

Before ordering, trace the original belt routing and confirm which belt is being replaced.

Before Ordering

Confirm all of the following before ordering:

• The original belt number is M154958 or M110313.
• The replacement is for the mower-deck drive system.
• The supplier-listed belt size of approximately 5/8 inch by 111 inches matches the required path.
• The mower has a compatible deck configuration.
• The original belt routes through the same spindle and idler pulley arrangement.
• The belt is not being confused with the tractor traction-drive belt.
• On two-belt decks, the required belt is the secondary spindle-drive belt.
• For an X320 or X324, the deck has the compatible 48X rotatable-gauge-wheel configuration.
• The spindle pulleys, idlers, tension spring, and belt guides are in usable condition.

Do not install the belt until the replacement number, dimensions, routing position, and mower-deck configuration have been confirmed.

Common Symptoms of a Worn Secondary Deck Belt

• Primary belt moves but the mower blades do not turn correctly
• One or more blades turn slowly under mowing load
• Belt squeals when the PTO clutch engages
• Belt repeatedly jumps off an idler or spindle pulley
• Visible cracking, fraying, glazing, or burned belt surfaces
• Loose belt tension with the tension arm engaged
• Uneven blade speed across the mower deck
• Reduced grass-discharge or bagging performance
• Burning-rubber smell near the mower deck

Installation Notes

• Park the mower on a level surface and remove the ignition key.
• Disconnect the spark-plug leads before working near the mower deck.
• Photograph or sketch the existing belt routing before removal.
• Identify the primary and secondary belts before disassembly.
• Inspect all spindle pulleys and idler pulleys for bearing wear.
• Inspect the tension arm, tension spring, and belt guides.
• Confirm the V side and flat side of the belt contact the correct pulleys.
• Make sure the belt is seated completely inside every pulley groove.
• Rotate the deck pulley system manually before starting the mower.
