Shopping dozers graders compaction means making one important distinction first: are you adding a miniature machine to a collection or layout, taking on a repair project, or sourcing a radiator for full-size Caterpillar equipment? These four choices span all three purposes, so the right pick depends far more on intended use than on appearance alone.
Quick take
For a new diecast display piece, the Ertl Caterpillar Cat 12G is the dedicated 1:50-scale choice with all wheels described as moving. The Norscot CAT 163H is the smaller 1:87 HO-scale grader for a layout-oriented collection. The BRUDER #0698 is expressly a repair purchase, with a broken blade defining the project. The 8N0073 radiator belongs in a separate decision: it is a new engine-compartment part identified for Caterpillar 3304 and 3306 motor grader applications, not a collectible miniature.
Listed-price comparison
The listed range runs from USD 9.95 to USD 999.00, reflecting the difference between used scale equipment, a repairable vintage toy, a new diecast model, and a radiator.
| Item | Listed price | Relative bar |
|---|---|---|
| NORSCOT #55127 Caterpillar CAT 163H Motor Grader | USD 9.95 | |
| For Repair BRUDER Caterpillar CAT Bulldozer #0698 | USD 19.99 | |

Decision matrix
- Choose the Ertl Cat 12G when you want a new, yellow diecast Caterpillar 12G model in 1:50 scale and want the listed moving-wheel feature.
- Choose the Norscot CAT 163H when a used 1:87 HO-scale motor grader suits a road scene or compact construction-vehicle display.
- Choose the BRUDER #0698 only when a broken dozer blade is acceptable because the goal is repair, parts, or a vintage 1993 piece.
- Choose the Radiator 8N0073 when the Caterpillar 3304/3306 and 120G, 12G, 130G, 140G, or 160G wording matches the equipment part you need.
Product notes
Caterpillar Cat 12G Motor Grader - Ertl 1:50 Scale Diecast Model
The Ertl Caterpillar Cat 12G Motor Grader is the clearest fit for a collector seeking a new 1:50 diecast grader rather than a project or mechanical component. Its yellow finish, CAT 12G model designation, Limited Edition attribute, and description of functioning wheels give it a focused display-model identity. Choose it when the appeal is an authentic-style Caterpillar grader replica with wheels that move. The limitation is one of format: this is a 1:50 model, not the 1:87 HO-scale grader offered by Norscot, and it is a motor grader rather than the BRUDER dozer. Its listed price is USD 85.00.
NORSCOT #55127 Caterpillar CAT 163H Motor Grader, Die-Cast, C8
Norscot's CAT 163H offers the strongest match for a smaller-scale construction scene. The 1:87 scale and HO-scale description place it squarely in layout-friendly territory, while the die-cast, plastic, and rubber construction and functioning rubber tires add specific collector-oriented details. It is described as pre-assembled and ready for roadways, making its intended setting especially clear. Pick this CAT 163H when a compact motor grader is the goal. Its tradeoff is the used condition, and the description notes that original packaging is not included. At USD 9.95, it is the lowest-listed option in this comparison.
For Repair BRUDER Caterpillar CAT Bulldozer #0698 1/16 Scale GERMANY Vintage 93
The BRUDER Caterpillar CAT Bulldozer #0698 is for a distinctly different shopper: someone comfortable with a repair-focused vintage toy. Its 1993 manufacture year, Germany origin, yellow CAT dozer format, and larger 1:16 scale make it a recognizable restoration or parts candidate. The reason to choose it is direct and specific-its title says "For Repair," so the purchase aligns with a hands-on repair project rather than a ready display model. The crucial limitation is equally direct: the description identifies a broken dozer blade. That condition should be central to the decision, despite the relatively low USD 19.99 listed price.
Radiator 8N0073 Fits Caterpillar 3304 3306 Motor Grader 120G 12G 130G 140G 160G
The Radiator 8N0073 is the practical equipment-parts choice in a group otherwise dominated by scale vehicles. It is new, includes a cap, and carries 8N0073, CA8N0073, and 8N-0073 identifiers. The title connects it with Caterpillar 3304 and 3306 motor grader applications and names 120G, 12G, 130G, 140G, and 160G models; its placement is the engine compartment. Choose this option for a radiator requirement tied to those named applications. The limitation is its specialized role and USD 999.00 listed price: it is not interchangeable in purpose with a diecast grader or a vintage toy dozer.
Final recommendation by use case
For a new collector model, select the Ertl Cat 12G. For HO-scale roadways or a compact 1:87 construction display, the Norscot CAT 163H is the focused choice. For someone specifically seeking a vintage repair challenge, the BRUDER #0698 makes sense because the broken blade is plainly part of its proposition. Reserve the Radiator 8N0073 for the named Caterpillar motor-grader and engine applications; it solves an equipment-parts need rather than a collecting need.
