Our acreage picks
UDC Parts 532187256 54 in High Lift Mower Blades (3-Pack)
High-lift 3-blade set for 54 in Husqvarna zero-turn decks with a 5-point star center hole.
Who it's for: Husqvarna zero-turn owners with 54 in decks who want a high-lift 3-pack with stated support.
Who should skip it: owners of other brands or deck sizes, where the fitment does not apply.
Read the full review
The UDC Parts set replaces Husqvarna 532187256 and a long list of OEM numbers for 54 in decks, with an 18-1/2 in length, 2-1/2 in width, 5-point star center hole and 1-3/8 in air lift. The blades are high-strength steel, pre-sharpened, with a safety coating that wears off in initial use, and the listing says the edge can be resharpened.
It is the only pick here to state any warranty or support term: 1-year product support for manufacturing defects. The spec table lists 6.08 lb without clarifying whether that is per blade or per set.
Pros
- High-lift blades for 54 in Husqvarna zero-turn decks
- 5-point star center hole with full OEM cross-reference
- Pre-sharpened; listing says the edge can be resharpened
- 1-year product support stated for manufacturing defects
Cons
- Fits Husqvarna and Craftsman 54 in decks only
- No hardness figure stated for the steel
- Spec table lists 6.08 lb without saying per blade or per set
- Safety coating wears off, so the bare edge needs care in storage
Grasscool ZT1 54 High Lift Mower Blades for Cub Cadet 54 in
High-lift blade set for 54 in Cub Cadet, Troy-Bilt and Craftsman decks with a 6-point star center hole.
Who it's for: Cub Cadet, Troy-Bilt and Craftsman owners with 54 in decks who bag clippings and want stated hardness.
Who should skip it: anyone whose spindle is not a 6-point star, or who wants a stated warranty.
Read the full review
The Grasscool set is the spec-sheet leader: 40MnB steel at 42-47 HRC with tensile strength over 1,100 MPa, a cutting edge hardened to 50 HRC or more, and a high-lift wing for bagging or side discharge. Dimensions are 18-1/2 in long, 2-3/8 in wide, 5/32 in thick, with a 6-point star center hole and 1-7/32 in air lift.
The spec table contradicts the bullets on weight and item count, listing 3.2 ounces and 5 items; trust the bullets' blade-set description. No warranty term is stated, and the listing warns the 6-point star will not fit S-shaped spindles or 2021-and-newer models in some lines.
Pros
- High-lift wing design for bagging and collection systems
- 40MnB steel at 42-47 HRC with edge hardened to 50 HRC or more
- 2-in-1 blades for bagging or side discharge
- Fits Cub Cadet, Troy-Bilt and Craftsman 54 in decks
Cons
- No warranty term stated on the listing
- Does not fit mowers with an S-shaped center hole, per the listing
- Spec table lists 3.2 ounces, which cannot be right for steel blades
- Heaviest spec detail here, but no support term to back it
MowerPartsGroup Bad Boy 60 in Zero Turn Mower Blades (3-Pack)
Hi-lift 3-blade set for 60 in Bad Boy zero-turn decks, made in USA.
Who it's for: Bad Boy owners with 60 in decks who want thick USA-made hi-lift blades.
Who should skip it: anyone with a different brand or deck size.
Read the full review
The MowerPartsGroup 60 in set is three USA-made Reaper blades at 20-1/2 in long, 2-1/2 in wide and .250 in thick, the thickest in this group, with a 5/8 in center hole and hi-lift design. The powder-coated red finish and a long OEM cross-reference cover Bad Boy ZT, CZT, Maverick and Pup 60 in decks.
No warranty term is stated. The spec table lists 9 lb without clarifying per blade or per set, and the listing asks buyers to verify model, serial and part numbers before purchase.
Pros
- Hi-lift 3-blade set for 60 in Bad Boy decks
- Thickest blades here at .250 in
- Made in USA with powder-coated finish
- Wide OEM cross-reference for 60 in decks
Cons
- No warranty term stated on the listing
- Fits Bad Boy 60 in decks only
- Spec table lists 9 lb without saying per blade or per set
- Listing asks buyers to double-check fitment before purchase
GICOOL 42 in Blades for Toro TimeCutter Zero Turn Mowers (2-Pack)
Medium-lift 2-blade set in 40MnB steel for Toro 42 in TimeCutter zero-turn decks.
Who it's for: Toro TimeCutter owners with 42 in decks who want a dimensioned, coated medium-lift set.
Who should skip it: bagger users who want high lift, or owners of other brands.
Read the full review
The GICOOL set is a 2-pack of medium-lift blades for Toro 42 in TimeCutter decks: 21-9/16 in long, 2-1/4 in wide, 5/32 in thick, with a 5/8 in circle center hole and 7/8 in air lift. The 40MnB steel carries a rust-resistant coating on the cutting edge that wears off in use, and the listing gives every dimension in both inches and millimeters.
No warranty term is stated, and the 4.4 lb spec table weight is not broken out per blade or per set. Fitment covers the Toro TimeCutter 42 in models listed, plus Exmark cross-reference with a 5/8 in circle hole.
Pros
- Medium-lift 2-blade set for Toro 42 in TimeCutter decks
- 40MnB steel with rust-resistant coating on the cutting edge
- Full dimensions stated in inches and millimeters
- Fits a wide list of Toro 42 in models
Cons
- No warranty term stated on the listing
- 2-blade set only, for 42 in decks
- Medium lift, not the high lift baggers prefer
- Spec table lists 4.4 lb without saying per blade or per set
MowerPartsGroup Bad Boy 54 in Zero Turn Mower Blades (3-Pack)
Standard-replacement 3-blade set for Bad Boy 54 in zero-turn decks, made in USA.
Who it's for: Bad Boy owners with 54 in decks who want a like-for-like standard replacement.
Who should skip it: bagger users who want high lift, or owners of other brands.
Read the full review
The MowerPartsGroup 54 in set is three USA-made Reaper blades at 18-3/4 in long, 2-1/2 in wide and .204 in thick with a 5/8 in center hole, a standard replacement for Bad Boy 54 in decks from the MZ Magnum to the Outlaw lines. The powder-coated red finish matches its 60 in sibling.
No warranty term is stated, and the listing asks buyers to verify model, serial and part numbers before purchase. At .204 in it is the thinnest blade here, which suits standard replacement rather than heavy bagging duty.
Pros
- Standard-replacement 3-blade set for Bad Boy 54 in decks
- Made in USA with powder-coated finish
- Broad model fitment across Bad Boy 54 in lines
- Straightforward like-for-like replacement
Cons
- No warranty term stated on the listing
- Standard lift only, not high lift for bagging
- Thinnest blades here at .204 in
- Listing asks buyers to double-check fitment before purchase

Buying guide: the best mower blades for zero turn mowers
Match the deck and the center hole first
Nothing else matters if the blade does not fit. The UDC Parts set fits 54 in Husqvarna decks with a 5-point star center hole. The Grasscool set fits 54 in Cub Cadet, Troy-Bilt and Craftsman decks with a 6-point star center hole, and its listing warns it does not fit mowers with an S-shaped center hole. The two MowerPartsGroup sets use a 5/8 in center hole for Bad Boy 60 in and 54 in decks respectively. The GICOOL set uses a 5/8 in circle center hole for Toro 42 in TimeCutter decks. Check the OEM part number on your old blade; the listings here cross-reference dozens of them.
High lift, medium lift or standard
Lift is the wing at the blade’s trailing edge that stands grass up and moves clippings. The UDC Parts and Grasscool sets are high lift, and the Grasscool listing describes a high-lift wing that pushes clippings into a bagger. The MowerPartsGroup 60 in set is hi-lift, the GICOOL set is medium lift, and the MowerPartsGroup 54 in set is a standard replacement. If you bag clippings, high lift helps; see do zero turn mowers have baggers. For side discharge on weekly cuts, medium lift and standard blades do fine.
Steel and hardness
Two listings state their steel in detail. The GICOOL blades are 40MnB steel with a rust-resistant coating on the cutting edge. The Grasscool blades are heavy-duty 40MnB steel at 42-47 HRC with tensile strength exceeding 1,100 MPa, and the cutting edge is hardened to 50 HRC or more. The UDC Parts blades are described as premium high-strength steel, pre-sharpened with a safety coating that wears off in use. Harder edges hold sharpness longer; the tradeoff is that all blades dull eventually and need resharpening or replacement.
Sets of three vs sets of two
Zero-turn decks run multiple blades, and the listings sell them as sets. The UDC Parts, MowerPartsGroup 60 in and MowerPartsGroup 54 in listings are 3-blade sets; the GICOOL listing is a 2-blade set for 42 in decks. Replacing all blades at once keeps the cut even and the deck balanced. The UDC Parts listing notes the cutting edge can be resharpened to extend blade life.
When to replace
Replace blades when the cutting edge is rounded, nicked or bent, or when the sail (the lift wing) is worn thin. A blade that vibrates or cuts unevenly after hitting a rock or stump should come off for inspection. Keep a spare set on the shelf; see best type of mower blades for the blade styles and best mower blade sharpener for lawn tractors if you sharpen your own.
Lawn size, deck width and speed in; minutes per mow out. Or work backward from the time you want to spend.
Zero-turns steer and brake through the rear wheels, so they can lose traction on slopes, wet grass and near ponds, ditches and drop-offs. Stay within the slope rating in your manual, keep well back from water and edges, use the ROPS and seat belt, never carry passengers, keep children and pets out of the yard, and disengage the blades before reversing. Refuel only with the engine off and cool. See CPSC riding lawnmower safety. Read our Safety Disclaimer.
Matching It to Your Property
- 54 in decks: the UDC Parts set (5-point star, Husqvarna) and the Grasscool set (6-point star, Cub Cadet, Troy-Bilt, Craftsman) cover the common 54 in zero-turn decks.
- 60 in decks: the MowerPartsGroup 60 in set is the only 60 in pick here, in a hi-lift 3-blade set for Bad Boy decks.
- 42 in decks: the GICOOL 2-pack fits Toro 42 in TimeCutter decks, a match for smaller properties and tighter gates.
- Bagging setups: the high-lift UDC Parts and Grasscool sets suit baggers and collection systems; confirm your bagger’s fit with the deck.
- Storage: blades are steel and take little room; keep the spare set dry and keep the OEM part number with it so the next order is easy.
The Acre Score explained
The Acre Score weighs five factors: performance (cut quality and lift), build quality (steel and stated hardness), value (what the set includes for the deck it fits), safety and warranty.
| Product | Acre Score | Perf. /35 | Build /25 | Value /25 | Safety /10 | Warranty /5 |
|---|---|---|---|---|---|---|
| UDC Parts 532187256 | 9.6 | 29 | 21 | 20 | n/a | 3 |
| Grasscool ZT1 54 | 9.6 | 32 | 22 | 20 | n/a | 0 |
| MowerPartsGroup 60 in | 9.6 | 30 | 22 | 19 | n/a | 0 |
| GICOOL Toro 42 in | 9.6 | 29 | 20 | 20 | n/a | 0 |
| MowerPartsGroup 54 in | 9.6 | 28 | 21 | 19 | n/a | 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. Safety counts only for powered gear or where the listing states safety features; where it does not apply, the score is taken over the remaining 90 points.
FAQ: mowing large lots
How do I know my zero-turn blades need replacing?
Ragged or brown-tipped grass after mowing, stragglers left standing, and new vibration from the deck are the signs. Pull the blades and look for a rounded or nicked cutting edge and a worn lift wing.
What does the center hole shape mean?
It is how the blade keys to the spindle. These listings show three types: a 5-point star (UDC Parts, for Husqvarna), a 6-point star (Grasscool, for Cub Cadet and others), and a 5/8 in circle (both MowerPartsGroup sets and the GICOOL set). The shape must match your spindle; a star blade will not seat on a round-hole spindle.
High lift vs medium lift blades?
High-lift blades move more air, standing grass up for a cleaner cut and pushing clippings into a bagger. Medium-lift blades are the middle ground for side discharge. Two picks here are high lift, one is hi-lift, one is medium lift and one is a standard replacement.
Can I sharpen mower blades myself?
Yes, and the UDC Parts listing notes its blades can be resharpened to extend blade life. Keep the factory angle, remove equal material from both ends, and check the listings’ specs for your blade’s dimensions. A dedicated sharpener keeps the angle consistent; see the best mower blade sharpener for lawn tractors.
Will these blades fit my mower?
Only if the deck size, center hole and OEM part number match. Each listing cross-references OEM numbers: 532187256 for the UDC Parts set, 038-0005-00 and 038-0001-00 for the MowerPartsGroup 54 in set, 110-6568-03 for the GICOOL set, and 942-05056A for the Grasscool set. When in doubt, pull an old blade and compare.
