Description

Greenworks Commercial OptimusZ 72" Mulch Kit with Blades is a mower accessory identified as model MK721 and product code 7517402. The supplied product listing describes this package as an OptimusZ 72-inch ZTR mulch kit with blades, intended for use with a 72-inch OptimusZ mower deck. A mulch kit is designed to support mulching applications by combining the kit components with the included blades, making it a practical accessory for operators who want a dedicated setup for their compatible OptimusZ equipment.

Product Overview

This Greenworks Commercial kit is listed as a combination of a mulch kit and blades for 72-inch OptimusZ decks. The product identity and intended application are based on the supplied product listing. The MK721 designation and product code 7517402 should be checked against the mower and deck identification before ordering, particularly because this specific variant is not currently listed in the Greenworks Commercial manufacturer catalogue supplied for verification.

Key Features

Mulch kit supplied with blades, according to the product listing.
Intended for a 72-inch OptimusZ mower deck.
Supplied variant designation: MK721.
Product code: 7517402.

Application

The supplied listing identifies this product as an OptimusZ 72-inch ZTR mulch kit with blades. It is intended for use with a compatible 72-inch OptimusZ deck. Confirm the mower model, deck configuration, and existing accessory requirements before purchase or installation. Compatibility with individual mower models beyond the supplied 72-inch OptimusZ deck description has not been independently verified for product code 7517402.

Important Compatibility Information

Greenworks Commercial’s current catalogue separately lists an accessory identified as CZ72MB3, SKU 7517302, described as an OPTIMUS 72-inch Mulch Blade Set that fits the OZ972R mower. That catalogue item is a different product and has not been merged with this MK721 listing. The related OZ972R mower is identified as a Series 9 72-inch rear-discharge OptimusZ ride-on ZTR, SKU 7421002. Because the manufacturer catalogue variant for product code 7517402 was not confirmed, the CZ72MB3 specifications and OZ972R fitment should not be treated as confirmed compatibility for this product.
