Cub Cadet 46" Deck Rebuild Kit Guide – LT1045, LT1046 & LTX1045/LTX1046
Cub Cadet LT1045, LT1046, LTX1045 and LTX1046 model names look very similar, but their 46-inch mower decks can use completely different blade, spindle and belt configurations.
This guide compares the LT1045/LT1046 3-blade deck with the LTX1045/LTX1046 2-blade deck and shows the differences between Green Dade 80-DK-010, 80-DK-031, 80-KT-002 and 80-DK-013.
Important:
Do not select a rebuild kit based only on “46-inch Cub Cadet.”
The LT1045/LT1046 configuration covered here uses
3 blades and 3 spindles, while the LTX1045/LTX1046
configuration uses 2 blades and 2 spindles.
LT1045 / LT1046 vs LTX1045 / LTX1046
LT1045 / LT1046
Uses three blades: one shorter blade and two longer blades, together with three spindle assemblies.
LTX1045 / LTX1046
Uses a different two-blade and two-spindle platform with different blade, spindle and belt OEM references.
Similar Name, Different Deck
LT1046 and LTX1046 sound almost identical, but their deck components should not be treated as interchangeable.
How to Identify the Correct Deck
1
Confirm the full mower model.
Determine whether the mower is LT1045, LT1046, LTX1045,
LTX1046, LTX1046M or LTX1046VT.
2
Count the blades.
The LT configuration covered here has three blades.
The LTX configuration covered here has two.
3
Compare OEM blade and spindle numbers.
Matching the blade count is helpful, but OEM references provide
a stronger fitment confirmation.
4
Decide how complete a repair you need.
For the LT platform, Green Dade offers blades only,
blades + spindles, or a more complete deck rebuild package.
Family 1: LT1045 / LT1046 46" 3-Blade Deck
3 Blades + 3 Spindles
Selected Cub Cadet LT1045, LT1046, iT1406 and related 46-inch applications.
One of the easiest ways to recognize this deck is its unusual three-blade arrangement. It uses one shorter blade and two longer blades, all with a special 6-point star center.
The shorter blade replaces the 742-04124 / 942-04124 family. The two longer blades replace the 742-04125 / 942-04125 family.
Green Dade offers three different repair levels for this platform: 80-KT-002, 80-DK-010 and 80-DK-031.
Compare the LT1045 / LT1046 Options
| Component | 80-KT-002 | 80-DK-010 | 80-DK-031 |
|---|---|---|---|
| 3 blades | Included | Included | Included |
| 3 spindle assemblies | — | Included | Included |
| 754-04153 / 954-04153 deck belt | — | — | Included |
| 956-04129-style idler | — | — | Included |
| 756-0627D-style idler | — | — | Included |
| Best choice when | Only blades need replacement | Blades and spindles need replacement | Blades, spindles, belt and idlers need replacement |
The important difference:
80-DK-010 and 80-DK-031 use the same basic LT1045/LT1046
blade-and-spindle platform. 80-DK-031 is the more complete package
because it also includes the deck belt and two idler pulleys.
LT1045 / LT1046 Blade Configuration
1 × Shorter Blade
Approximately 14-13/16" long. Replaces 742-04124 / 942-04124 and related references.
2 × Longer Blades
Approximately 16-1/4" long. Replace 742-04125 / 942-04125 and related references.
Special 6-Point Star
The special 6-point star blade center is another useful fitment check for this deck configuration.
Family 2: LTX1045 / LTX1046 46" 2-Blade Deck
Different 2-Blade Platform
Selected LTX1045, LTX1046, LTX1046M and LTX1046VT applications.
Green Dade 80-DK-013 is not simply another completeness level of the LT1045/LT1046 kits. It belongs to a different deck configuration.
It uses two spindle assemblies replacing the 618-04636 / 918-04636 / 918-04865 family, along with two approximately 23-1/4" blades.
The blades replace references including 742-04290 / 942-04290, while the belt replaces 754-04219 / 954-04219.
It also includes two idler pulleys in the 756-04129 / 956-04129 family.
LT Platform vs LTX Platform
| Feature | LT1045 / LT1046 | LTX1045 / LTX1046 |
|---|---|---|
| Blade count | 3 | 2 |
| Spindle count | 3 | 2 |
| Blade arrangement | 1 shorter + 2 longer | 2 × approx. 23-1/4" |
| Blade OEM family | 742-04124 + 742-04125 | 742-04290 / 942-04290 |
| Spindle family | 618-0660 / 918-0660 / 618-04137 family | 618-04636 / 918-04636 / 918-04865 family |
| Deck belt | 754-04153 / 954-04153 | 754-04219 / 954-04219 |
| Green Dade products | 80-KT-002 / 80-DK-010 / 80-DK-031 | 80-DK-013 |
Easy mistake to avoid:
LT1046 and LTX1046 sound almost identical, but the configurations
covered here use different blade counts, spindle counts, spindle
families and belt OEM numbers.
Which Product Should You Choose?
A
LT1045/LT1046 and only the three blades need replacement.
Choose 80-KT-002.
B
LT1045/LT1046 and you need blades plus the three spindles.
Choose 80-DK-010.
C
LT1045/LT1046 and you also need the belt and idler pulleys.
Choose the more complete 80-DK-031.
D
LTX1045/LTX1046 with the two-blade configuration.
Check 80-DK-013 and verify all listed OEM
numbers against your mower.
Common Signs Your Deck Needs Service
Uneven Cut
Bent blades, worn spindle bearings or excessive spindle play can contribute to an uneven cut.
Grinding or Bearing Noise
Worn spindle or idler bearings may produce grinding, rumbling or squealing noises.
Belt Slipping
Inspect the belt, idlers, pulleys and belt routing rather than automatically replacing only the belt.
Excessive Vibration
Damaged blades, worn spindles and pulley problems can all contribute to deck vibration.
Damaged Blades
Replace blades that are bent, cracked, heavily worn or unable to maintain a proper cutting edge.
Multiple Worn Components
If several parts are worn at the same time, a rebuild kit may be more practical than purchasing components individually.

Frequently Asked Questions
Do LT1045 and LTX1045 use the same 46" deck rebuild kit?
No. The configurations covered here use different blade counts, spindle families and belts. Always confirm whether your mower is an LT or LTX model.
Do LT1046 and LTX1046 use the same deck parts?
No. Their names are similar, but the deck configurations covered here differ significantly.
What is the difference between 80-DK-010 and 80-DK-031?
Both use the same LT1045/LT1046 three-blade platform. 80-DK-010 contains the three spindles and three blades. 80-DK-031 adds the deck belt and two idler pulleys.
What is 80-KT-002?
It is the three-blade replacement set for the compatible LT1045/LT1046 configuration and does not include spindles, belt or idler pulleys.
What does 80-DK-031 include?
It includes three spindle assemblies, three blades, one 754-04153/954-04153-style deck belt and two idler pulleys.
What does 80-DK-013 fit?
It is intended for the separate two-blade configuration used on selected LTX1045, LTX1046, LTX1046M and LTX1046VT applications, as well as other listed compatible models.
Can I use 80-DK-013 on an LT1045 or LT1046?
Do not assume so. 80-DK-013 uses a different two-spindle, two-blade platform. Verify the complete mower model and OEM references before ordering.
Is a 46-inch deck size enough to confirm compatibility?
No. Deck width alone does not determine fitment. Blade count, spindle design, belt and OEM numbers must also be checked.
How many blades does the LT1045/LT1046 configuration use?
Three blades: one shorter 742-04124-style blade and two longer 742-04125-style blades.
What information should I check before ordering?
Confirm the complete mower model, blade count and OEM numbers from the blades, spindles, belt and pulleys whenever possible.
Still Not Sure Which Cub Cadet 46" Deck You Have?
Start by confirming whether your mower is an LT or LTX model, then count the blades and compare your OEM part numbers.
