If you're shopping around grader equipment, the first thing to sort out is what kind of purchase you actually need. Are you looking for a display collectible, a reference manual for real equipment, or machine control hardware for a working motor grader? Listed prices here run from $50.00 to $5,299.00, so the right pick depends more on your role than on brand preference.
Quick Take
The four items split into three purposes: diecast collectibles (MiniMac Galion 850, Motorart Volvo G740B), a reference manual (John Deere 770G Parts Catalog), and machine control hardware (Trimble Earthworks TD540-W & EC520-W). The table below shows the stated prices and how they compare.
Listed Prices at a Glance

Product Notes
Diecast Galion 850 Motor Grader Die Cast 1:50 Scale Made In Brazil MINIMAC
The MiniMac Galion 850 is a die-cast replica of a Galion motor grader, finished in yellow and made in Brazil. It is the least expensive option in this set, so it works well if you want a low-commitment collectible or a gift for someone who likes road grader equipment. The model is used, which is the main factor to weigh before choosing it. For display purposes, the die-cast build gives it a solid feel, but used condition means it may show signs of handling. If you need a factory-fresh piece, this one may not satisfy that requirement.
Motorart 13152 1:50 Volvo G740B Motor Grader EX
The Motorart Volvo G740B is a branded Volvo grader model aimed at ages 17 and up. The Volvo name is the clear draw here, giving it a different personality from the MiniMac Galion. It is used, and the shell has small paint chips; the original box and instruction manual are not included. That combination makes it a good choice for a collector who focuses on the machine itself rather than packaging, but a poor fit if you want a mint-in-box piece. The visual appeal of the grader still carries the model, even if the extras are missing.
John Deere 770G Motor Grader Parts Catalog Manual - PC15374
The John Deere 770G Parts Catalog is a brand-new, sealed reference manual with 880 pages and serial number coverage listed as ALL. If you maintain a 770G motor grader, this is the practical answer for parts identification. The limitation is scope: it is a parts catalog, not a technical/service manual, so it will not give you step-by-step repair procedures. Choose it when your project involves finding the right parts, not full service guidance. For anyone who works on these machines, the manual is far more useful than a display model.
TRIMBLE EARTHWORKS TD540-W & EC520-W MOTOR GRADER LIC TD520 639-0559 200435-10
The Trimble Earthworks package combines a TD540-W display and EC520-W control module, and the title connects it to motor grader license TD520. For someone working in the field, this is the only option here built for machine control on a real grader. The model numbers in the title are specific enough to match against existing equipment. The trade-offs are the high price and the fact that cables are not included. Treat this as a significant investment, not an add-on collectible. If your need is operational rather than decorative, this is the product that addresses that job directly.
Final Recommendation by Use Case
Match the purchase to the job: the MiniMac Galion 850 if you want an affordable display model; the Motorart Volvo G740B if you accept used wear in exchange for a Volvo-branded grader; the John Deere 770G Parts Catalog if you need parts information for real equipment; and the Trimble Earthworks TD540-W & EC520-W if you need on-machine control hardware for a motor grader. The products do not directly compete with each other, so use case should drive your decision.
