Exact-fit replacement belt

The Stens 265-137 is a new OEM replacement belt built for Exmark Lazer Z mowers equipped with 52, 60 or 72 inch decks carrying serial numbers 369 999 and lower. It replaces Exmark part numbers 1-633173 and 633173 and arrives in a branded sleeve ready for installation.

5/8 inch covered mule-drive belt

This belt is a covered type measuring 5/8 inch wide and 111 1/2 inches long, designed specifically for the mule-drive application on the listed decks. The width and length combination is the single specification that determines whether the belt will seat and track correctly on your machine.

Handles three deck sizes with one part

One belt covers the 52, 60 and 72 inch deck range on Lazer Z models up to the stated serial break, simplifying inventory for fleets and owners with multiple units. It will not fit decks outside that width range or machines with serial numbers above 369 999, so verify both measurements before ordering.

Questions about this item

How does the 111 1/2" length work once the belt is routed around the mule-drive pulleys on a Lazer Z?

The 111 1/2" length is the installed circumference that matches the factory routing on 52", 60" and 72" decks up to serial 369,999.

What does the 5/8" width mean for pulley compatibility on the Exmark mule drive?

The 5/8" covered width fits the OEM mule-drive groove profile used on Exmark 1-633173 without shims or adapters.

What physical clearance does the covered belt need to mount on a Lazer Z deck?

The covered construction sits in the standard mule-drive channel on 52", 60" and 72" decks; no extra bracket or tensioner modification is required.
