Lawn Mower 1-653368 Belt 5/8"x154" Fits for Exmark Lazer Z HP with 52" Deck 1-653368 653368 116-3455 653368 Hustler 604711 Husqvarna 539114557, for LSZ4622 RZ5422 RZ5424 with 52" and 54" Deck

What It Is

This is a replacement drive belt for zero-turn mowers, specifically engineered for Exmark Lazer Z HP models with a 52-inch deck and compatible Husqvarna/Hustler models with 52- or 54-inch decks. It transfers engine power to the cutting deck spindles and is a wear item that needs periodic replacement.

Fitment & Compatibility

Before buying, confirm three things:

• Deck size: This belt is 5/8 inch wide and 154 inches long. It fits 52-inch decks on Exmark Lazer Z HP models (LSZ4622, RZ5422, RZ5424) and 52/54-inch decks on select Husqvarna and Hustler models.
• Model numbers: Check your mower’s model tag. Compatible OEM numbers include Exmark 1-653368, 653368, 116-3455; Hustler 604711; Husqvarna 539114557.
• Aftermarket note: This is a non-OEM belt. Measure your existing belt length and width to be sure—aftermarket belts can vary slightly in tension or groove depth. Verify the routing diagram matches your deck.

Key Things to Know

• Quality: Rated 4.4/5 from 125 reviews. Users report good durability for the price, but some note it may stretch slightly more than OEM belts during break-in.
• Installation: Moderate difficulty. You’ll need to remove the deck belt guard and possibly the idler pulley to slip the belt on. A belt tension tool helps.
• Common gotcha: Double-check the belt length—154 inches is specific. A 153- or 155-inch belt won’t tension correctly and can slip or damage pulleys.
• Lubrication: No need. Just install and check tension after the first hour of use.

Should You Buy It

If you own an Exmark Lazer Z HP with a 52-inch deck or a compatible Husqvarna/Hustler model and need a cost-effective replacement, this belt is a solid choice. It’s not OEM, but reviews suggest reliable performance for the price. Skip it if you want factory-spec fitment or have a different deck size—measure first to avoid returns.
