Motor grader

01

Keep gear, drive mode and equipment with the rating

The Cat 140 sheet gives net power at the flywheel with fan, air cleaner, muffler and alternator fitted. Its VHP Plus forward-gear chart runs from 132 kW in first to 186 kW in eighth; the AWD-on column runs from 147 to 201 kW. Do not combine the first value from one column with the last from another. [1]

The same sheet lists “Typically Equipped” total mass of 19,198 kg for the tandem machine and 20,236 kg for AWD. Its equipment basis includes full fluids, operator, push block, transmission guard, rear ripper/scarifier and the specified tyres and rims, among other equipment. These are not bare-machine weights. [1]

Deere’s 670G/GP Final Tier 4/Stage V chart lists 134 kW in first gear and 175 kW in eighth. Its Tier 3/Tier 2 column reaches 172 kW in eighth instead. Identify the engine/emissions version with each quotation. [3]

02

Treat blade pull as a conditional specification

Komatsu’s GD655-7 brochure lists blade pull of 12,607 kg at base gross vehicle mass with ripper and 14,697 kg at maximum gross vehicle mass with ripper. These are the brochure’s published units and labels. Its calculation assumes a 0.9 traction coefficient under no-slip conditions; it does not measure the available pull on the proposed site. [2]

Deere lists 15,501 kg blade pull at maximum operating weight for the 670G/GP. Its maximum operating weight is 24,948 kg. Do not attach that pull figure to the lighter base configuration. [3]

03

Retain the differing Komatsu weight publications

The linked Australia/New Zealand GD655-7 brochure states approximately 19,730 kg with rear ripper, front push plate, full fuel, lubricants and coolant, on its specified tyres and rims. The current Australian product webpage states operating weight of 20,200 kg. Both are retained here because the publications differ; the webpage does not reconcile its basis with that brochure. Confirm the offered configuration and weight with Komatsu or the supplying dealer. [2] [5]

Deere’s Final Tier 4 base-machine figure is 16,000 kg with its stated fluids, operator, moldboard, cutting edge and tyres. Its “Typically Equipped” figure is 19,230 kg, including front push block, rear ripper/scarifier and other equipment. A cross-brand power-to-weight ranking using unmatched configurations would conceal these differences. [3]

04

Use the engine compliance basis, not a gear net-power figure

The cited emissions rule addresses nonroad diesel engines and distinguishes transient and steady-state requirements. Its power categories and engine applicability cannot be established by taking a machine’s gear-dependent net flywheel rating alone. Obtain the engine family, maximum-engine-power classification and applicable certificate for the offered machine. [4] [6]

The earlier blanket numerical emissions-limit summary is omitted: the rule includes applicability and averaging/banking/trading provisions that a single unqualified comparison row would conceal. Read the applicable provisions and certificate for the actual engine. [4] [6]

05

Compare complete configurations before ranking machines

Read the power chart, mass footnote and blade-pull condition together. These specifications describe different measurement or calculation bases; they are not a measured ranking of grading output. [1] [2] [3]

06

Define the machine and attachment arrangement

The cited brochures distinguish drive arrangements and optional work equipment. State whether the quotation includes ripper, scarifier, front push equipment and the requested grade-control provision. A cabin, blade or replacement chain is outside this complete-machine scope. [1] [2]

07

Check the work equipment as an installed assembly

Confirm the moldboard, circle, drawbar, hydraulic controls and supplied attachments against the selected configuration. Obtain the applicable dimensional drawing and operating instructions for the offered arrangement. The brochures’ dimensions and capacities do not establish that every option is fitted. [2] [3]

08

Give the supplier the configuration and operating duty

Provide the intended grading work, material, terrain, attachment list, transport constraints, engine compliance requirement and service location. Request the exact machine configuration, power chart and weight statement with the quotation.
