109-4199 Mule Drive Belt Fits Exmark Lazer Z XS Diesel 5/8 x 123 Aramid

What You Are Getting

One new aftermarket replacement drive belt built to replace Exmark 109-4199, which Exmark later superseded to 109-4199-SL. This is the engine-to-deck mule drive belt. It carries power from the engine pulley down to the cutting deck drive on Kubota diesel powered Lazer Z XS and Lazer Z DS-Series zero-turn mowers.

Built to Take Commercial Diesel Duty

The belt uses an aramid cord core inside a wrapped and molded body with a double cover. Aramid holds up to the heat, stretch, and shock load that a diesel zero-turn throws at a drive belt, so it keeps proper tension longer than a standard belt and stands up to daily commercial cutting.

Specifications

- Top width: 5/8 in (16 mm)

- Outside length: about 123 in (3124 mm)

- Section: wrapped and molded V-belt (HB)

- Core: aramid cord, double cover

- Job: engine-to-deck mule drive (clutching)

- Sold as a single belt

Fitment

Fits Kubota diesel powered Exmark Lazer Z XS and Lazer Z DS-Series zero-turn mowers with 60, 66, and 72 in decks (25 hp Kubota diesel). Gas-engine Lazer Z models use a different belt. Always match your model and serial number before ordering, since Exmark changed belt routing across build dates.

Replaces

Exmark 109-4199, Exmark 109-4199-SL, Ferris 5103907, Rotary 13255. If your current belt is cracked, glazed, frayed, or slipping, swapping it brings back full blade engagement and a clean, even cut.
