Ariens / Gravely Lawn Mower 42" Mulch Ki vs Honda 81330-VG4-010 and 81320-VG4-010 La
Quick Verdict
The Ariens/Gravely Mulch Kit (Part# 71513900) and the Honda Fabric Bag set (Parts# 81330-VG4-010 and 81320-VG4-010) serve completely different purposes. The Ariens/Gravely is a dedicated mulching accessory for zero-turn mowers, while the Honda is a bagging attachment for a push mower. Neither is a complete mower—they are add-ons. The choice depends on whether you need to mulch clippings on a large lawn with a ZT-X mower or bag clippings on a smaller lawn with a compatible Honda walk-behind.

Where Ariens Wins
The Ariens/Gravely Mulch Kit excels for owners of ZT-X zero-turn mowers with 42-inch decks who want to eliminate bagging. It allows you to leave finely chopped clippings on the lawn, returning nutrients to the soil. This saves time and effort on large properties—no stopping to empty bags. The kit is designed for durability, handling tough grass conditions without clogging as easily as some universal kits. At $205.95, it is slightly cheaper than the Honda bag set. It also suits users who prefer a clean, mulch-only look without discharge or collection.
Where Honda Wins
The Honda Fabric Bag set is best for those who want a clean, manicured lawn free of clippings. It collects grass into a white fabric bag, which is lighter than older plastic bags and easier to empty. The bag attaches to specific Honda mowers, likely HRX or HRC series, known for reliable engines and excellent cut quality. The 4.2/5 rating from 29 reviews suggests high customer satisfaction with fit and performance. It also allows for versatile lawn care—you can bag in spring/fall and mulch or side-discharge at other times. The $227.55 price is competitive for a dedicated bagging system.
Which Should You Buy
Choose the Ariens/Gravely Mulch Kit if: You own a compatible ZT-X zero-turn mower with a 42-inch deck and primarily want to mulch clippings. Ideal for large lawns (0.5+ acres) where bagging is impractical. You prefer nutrient recycling and less frequent stops.
Choose the Honda Bag Set if: You own a compatible Honda push mower and want to bag clippings for a clean look or composting. Best for smaller lawns (under 0.75 acre) where a zero-turn is overkill. You value the flexibility to switch between bagging and mulching.
Do not buy either if you do not own the corresponding mower—these are accessories, not standalone
