If you are shopping for a dozer or grader model, the hardest part is choosing a scale and a budget before you fall in love with a photo. The four listings in this guide are a good cross-section: an accessory set for a 1:64 John Deere crawler, a 1:50 motor grader, a 1:50 dozer, and a 1:25 dozer. Their listed prices run from $10 to $325, so you could pick one or build a small fleet. The question is not which one is "best" - it's which one matches the space you have and the scene you want to create.
Quick take
- For a single small shelf: the $10 Ertl track set is only replacement tracks, not a full vehicle.
- For a 1:50 collection: the $115 Allis Chalmers HD-21 is a new diecast in an unopened box.
- For a grader specifically: the $50 MINIMAC Galion 850 is the only grader here.
- For a large display: the $325 First Gear International Harvester 175 is the biggest, at 1:25 scale.

Replica Track Set Ertl - John Deere Crawler 1:64 - Yellow 3D TPU
At $10, this is the most affordable item in the comparison, but it is not a complete dozer. It is a set of two replacement tracks for an Ertl 1/64 scale John Deere 850J crawler dozer, made from yellow 3D-printed TPU plastic. The description says the tracks are a close match to the OEM version and include guide tracks on the inside, with a width of 8 mm. If you have this specific crawler and need new tracks, this is a direct, low-cost fix. The limitation is that it only works for that model - you are not getting a vehicle to display.
Diecast Galion 850 Motor Grader Die Cast 1:50 Scale Made In Brazil MINIMAC
Listed at $50, this used MINIMAC model is the only grader in the group. It's a 1:50 scale Galion 850 road grader in yellow, made of die-cast material and produced in Brazil. If you're building a 1:50 construction diorama or specifically want a grader rather than a dozer, this one gives you that machine at a lower listed price than the new 1:50 dozer in this comparison. The limitation is the condition: it's marked "Used", so you should expect signs of handling or wear compared to the new items here.
Allis Chalmers HD-21 Crawler w/ Straight Blade & Drawbar Diecast 1:50
Priced at $115, this First Gear 1:50-scale diecast is orange, new, and comes with an unopened box. The features list includes the straight blade and drawbar, and the description notes it was manufactured by First Gear and is recommended for ages 15 and up. For a collector who wants a shelf-ready dozer without hunting for used pieces, this is a straightforward pick. The limitation is the scale: at 1:50, it will be noticeably smaller than the 1:25 International Harvester, and the age recommendation means it's not a toy for young children.
First Gear 40-0127 1:25 Scale Diecast International Harvester 175 Crawler/Dozer
This is the highest-priced listing at $325, and it buys the largest scale in the comparison: 1:25. It's a yellow diecast International Harvester 175 crawler/dozer, listed as new and never removed from its box. The description notes the box has mild corner wear and is "sold as is" as shown in photos. If your priority is a big, detailed centrepiece, this is the one. The limitation is that at this price, you're paying for the scale and diecast construction, and the box wear might matter if you're a mint-in-box collector.
Final recommendation by use case
- Need replacement tracks for a 1:64 Ertl John Deere crawler? Get the Replica Track Set Ertl.
- Want a grader model at a lower price? The MINIMAC Galion 850 is the one to buy.
- Want a new 1:50 dozer with an unopened box? The Allis Chalmers HD-21 from First Gear fits.
- Want the biggest scale and don't mind the highest price? The First Gear International Harvester 175 is the showpiece.
If you're still deciding, think about your display space and whether you want a complete machine or an accessory. That will push you toward one of these four faster than any list of measurements.
