How to choose the best lawn mower blade for bahia grass
Match the blade to the deck and spindle
Start with length and the center hole. The two 42 in deck blades here are 21 in long: the Chway 2-pack and the 2PK Gator G5 at 21-3/16 in. The Chway uses a 5-point star center hole and the 2PK uses a 5/8 in 6-point star, and the Chway bullets warn that a wrong spindle pattern is the most common cause of a blade not fitting. The Oregon 96-900 and 596-900 are 21 in blades for 21 in decks, and the Greenworks blade is model-specific for 19 in Greenworks corded mowers.
High-lift or mulching edge
The Oregon Gator G3 is the high-lift pick: the listing says its aggressive blade angle increases air flow to push debris up and out for bagging or side discharge. The Gator G5 596-900 is fused with carbide for a tougher cutting exterior, with the listing claiming superior mulching and bagging. The Chway pair is a mulching and high-lift blade with a 1-1/16 in lift. For more on edge types, see our best type of mower blades guide.
What the listings do not state
No listing here states a warranty term, and none states a safety certification. The Greenworks spec table lists an item weight of 0.27 g, which reads as a listing error for a steel blade; the 2PK Gator G5 is the only one with a stated package weight at 5.59 lb. When a blade fits your deck but the listing is thin on specs, see our best mower blades for lawn tractors for how listings usually read.
Matching It to Your Property
- For 42 in decks, buy the pair that matches your spindle: 5-point star on the Chway 2-pack, 6-point star on the 2PK Gator G5.
- For 21 in decks, the Oregon Gator G3 and G5 are both 21 in; the G5 adds the carbide-fused edge.
- For a 19 in Greenworks corded mower, only the Greenworks 17.72 in blade lists your models.
- Blades are wear parts: keep a spare set and a sharpener, and check the listing for a stated weight before judging shipping.
Read the manual, keep children and pets out of the yard while you work, wear eye and hearing protection and sturdy footwear, and never exceed the slope rating of your machine. Refuel only with the engine off and cool. See CPSC lawn mower safety. Read our Safety Disclaimer.
The Acre Score explained
The Acre Score weighs performance, build, value, safety and warranty. For a mower blade, safety means stated safety certifications or protections the listing actually claims; none of the five listings states any, so safety scores zero across this guide. No listing states a warranty term either, so warranty scores zero as well. How we pick explains the weights.
| Product | Acre Score | Perf. /35 | Build /25 | Value /25 | Safety /10 | Warranty /5 |
|---|---|---|---|---|---|---|
| Oregon Gator G5 596-900 | 9.5 | 32 | 22 | 20 | 0 | 0 |
| Oregon Gator G3 96-900 | 9.5 | 30 | 21 | 21 | 0 | 0 |
| Chway 42in Mulching 2-Pack | 9.5 | 29 | 20 | 22 | 0 | 0 |
| 2PK Gator G5 598-629 | 9.5 | 29 | 20 | 21 | 0 | 0 |
| Greenworks 19in Blade | 9.4 | 28 | 20 | 20 | 0 | 0 |
Scores run from 9.2 to 9.8: each product’s point total is placed on that range, so more points always means a higher score.
FAQ: mowing large lots
What size blade fits a 42 inch deck?
The 42 in deck blades here are 21 in long: the Chway 2-pack and the 2PK Gator G5 at 21-3/16 in. Match the center hole too: 5-point star on the Chway, 5/8 in 6-point star on the 2PK.
Gator G3 or Gator G5 for bahia grass?
The G5 596-900 is fused with carbide for a tougher cutting edge, and the G3 96-900 is the high-lift version. Both are 21 in Oregon blades. The listing positions the G5 for tougher cutting and the G3 for bagging and side discharge.
How do I know the center hole pattern?
The Chway bullets warn that a wrong spindle pattern is the most common cause of a blade not fitting: remove the old blade and compare the center hole shape before ordering. The Chway and the Oregon 596-900 use a 5-point star; the 2PK 598-629 uses a 6-point star.
Will these fit my mower?
Match the blade length, center hole and deck. The Greenworks blade is model-specific for 19 in Greenworks corded mowers, and the 42 in deck blades name Craftsman, Husqvarna, Poulan Pro, MTD, Troy Bilt and Cub Cadet models. When in doubt, measure the old blade.
Do any of these state a warranty term?
No. The Oregon listings state Defects in Material and Workmanship with no term, and the other listings state no warranty, so warranty scores zero across this guide.
