John Deere 772G Vs. 670G: Which Used Grader Fits Your Job?"},"content":{"rendered":"<p><span style=\"font-weight: 400;\">Two contractors call us on the same morning. Both need a used motor grader for what sounds like the same project. One maintains county gravel roads, blading light and often, mile after mile. The other cuts road subgrade in wet clay and needs the machine to keep its footing on every pass. They should not buy the same grader.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">That is the question behind most Cat 140 vs John Deere 772 and Cat 140 vs John Deere 670 searches. The Caterpillar 140M, John Deere 670G and John Deere 772G overlap, but each makes a different trade-off between weight, power and traction.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Our short answer: a Cat 140M or John Deere 670G covers most maintenance and general site work. The 772G earns its extra cost when heavy cuts and poor traction decide your production. Configuration, condition, and ownership cost matter more than the badge on the hood.<\/span><\/p>\n<div id=\"ez-toc-container\" class=\"ez-toc-v2_0_88 counter-hierarchy ez-toc-counter ez-toc-grey

The 670G sits close to the Cat on weight but above it on torque. In more detail:<\/span><\/p>\n<p><b><a href=\"https:\/\/usedmotorgrader.com\/caterpillar-140m2awd-m9j00887\">Cat 140M<\/a>.<\/b><span style=\"font-weight: 400;\"> A lighter, tandem-drive grader with a 7.2 L engine and joystick-only steering. Optional AWD moves it into a different traction class, so an AWD unit and a non-AWD unit are not the same buying decision.<\/span><\/p>\n<p><b>John Deere 670G.<\/b><span style=\"font-weight: 400;\"> Deere&#8217;s tandem-drive grader. It weighs within about 900 lb of the 140M at base weight but has a larger 9.0 L engine with more torque and torque rise.<\/span><\/p>\n<p><b><a href=\"https:\/\/usedmotorgrader.com\/john-deere-772gp-1dw772gpplf706434\">John Deere 772G<\/a>.<\/b><span style=\"font-weight: 400;\"> The same displacement, rated about 40 hp higher in the Tier 3 tables, with a heavier mainframe (108 in\u00b3 section modulus against 88 in\u00b3 on the 670G) and six-wheel drive.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Here is the point that catches buyers out. The 670G and 772G are not a like-for-like pair. Deere&#8217;s G-Series 6WD brochure lists the 772G alongside the 672G, and<\/span><a href=\"https:\/\/www.equipmentworld.com\/john-deere-g-series-tier-4-final\" rel=\"nofollow\"> <span style=\"font-weight: 400;\">Equipment World&#8217;s G-Series coverage<\/span><\/a><span style=\"font-weight: 400;\"> identifies the 672G, 772G and 872G as the six-wheel-drive models, which leaves the 770G as the tandem-drive counterpart. Comparing the 670G with the 772G changes power, weight, and drivetrain at once. To isolate the value of six-wheel drive, compare the 670G with the 672G, or the 770G with the 772G.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">The 772G is not automatically better. It costs more to buy and move, and its extra drive hardware is more to maintain. The 670G is not a lesser machine either. It simply does not carry the heavy-cut capacity many routine jobs never use.<\/span><\/p>\n<h2><span class=\"ez-toc-section\" id=\"Which_Grader_Fits_Your_Job\"><\/span><b>Which Grader Fits Your Job?<\/b><span class=\"ez-toc-section-end\"><\/span><\/h2>\n<h3><span class=\"ez-toc-section\" id=\"County_and_gravel_road_maintenance\"><\/span><b>County and gravel road maintenance<\/b><span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p><span style=\"font-weight: 400;\">Washboard repair, shoulder work, and drainage shaping involve shallow cuts and frequent passes. The blade is rarely traction-limited, so extra drive hardware sits idle. A Cat 140M or 670G is usually the better economic fit. The 772G suits soft subgrades, steep grades, or fleets that also do rehabilitation.<\/span><\/p>\n<h3><span class=\"ez-toc-section\" id=\"Road_construction_and_heavy_cutting\"><\/span><b>Road construction and heavy cutting<\/b><span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p><span style=\"font-weight: 400;\">This is where drivetrain matters. At maximum weight, Cat&#8217;s specalog rates the 140M at 29,670 lb of blade pull, or 45,787 lb with AWD. Deere rates the 670G at 34,173 lb and the 772G at 49,500 lb. The nearest rivals are an AWD 140M and a 772G. A tandem 140M or 670G can handle moderate cuts, but expect more wheel slip in heavy, wet material. Ballast helps: Cat lists a 2,000 lb push plate counterweight, and Deere lists a 2,950 lb front push block and a 1,603 lb rear counterweight. Adding weight over the drive wheels is often cheaper than stepping up a model.<\/span><\/p>\n<h3><span class=\"ez-toc-section\" id=\"Finish_grading_and_precision_work\"><\/span><b>Finish grading and precision work<\/b><span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p><span style=\"font-weight: 400;\">Precision depends on what is fitted, not on the model name. The 140M is Grade Control Ready, with AccuGrade attachment kits optional. On the Deere side, Grade Pro (GP) units include cross slope, and the brochures list SmartGrade and Topcon- or Trimble-ready options. Deere announced<\/span> <span style=\"font-weight: 400;\">factory-integrated SmartGrade later in the G-Series run, with a field kit for existing machines. Never assume a used unit has any of it.<\/span><\/p>\n<h3><span class=\"ez-toc-section\" id=\"Site_preparation_and_subdivisions\"><\/span><b>Site preparation and subdivisions<\/b><span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p><span style=\"font-weight: 400;\">Pads, access roads and drainage profiles reward versatility and a reasonable purchase price. The Cat 140M and 670G are the balanced choices. The 772G makes sense when the same machine also cuts heavy clay or must work through wet weather.<\/span><\/p>\n<h3><span class=\"ez-toc-section\" id=\"Snow_aggregates_and_demanding_sites\"><\/span><b>Snow, aggregates and demanding sites<\/b><span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p><span style=\"font-weight: 400;\">Cat lists snow plows, wings, and blade float for the 140M. Deere lists snow-pattern radials and a snowplow light bar. Confirm wing and plow compatibility for the exact serial number. We found no head-to-head snow test, so size and power alone prove nothing. Traction, visibility, and blade float matter more than the nameplate. For aggregate yards, a grader maintains haul roads and stockpile surfaces. It is not a substitute for a dozer or loader.<\/span><\/p>\n<h2><span class=\"ez-toc-section\" id=\"Job-fit_matrix\"><\/span><b>Job-fit matrix<\/b><span class=\"ez-toc-section-end\"><\/span><\/h2>\n<table>\n<tbody>\n<tr>\n<td><b>Application<\/b><\/td>\n<td><b>Cat 140M<\/b><\/td>\n<td><b>John Deere 670G<\/b><\/td>\n<td><b>John Deere 772G<\/b><\/td>\n<\/tr>\n<tr>\n<td><b>Municipal and county road maintenance<\/b><\/td>\n<td><span style=\"font-weight: 400;\">Strong fit<\/span><\/td>\n<td><span style=\"font-weight: 400;\">Strong fit<\/span><\/td>\n<td><span style=\"font-weight: 400;\">Suitable, depending on configuration<\/span><\/td>\n<\/tr>\n<tr>\n<td><b>Gravel-road maintenance<\/b><\/td>\n<td><span style=\"font-weight: 400;\">Strong fit<\/span><\/td>\n<td><span style=\"font-weight: 400;\">Strong fit<\/span><\/td>\n<td><span style=\"font-weight: 400;\">Suitable, depending on configuration<\/span><\/td>\n<\/tr>\n<tr>\n<td><b>Road construction and heavy cutting<\/b><\/td>\n<td><span style=\"font-weight: 400;\">Suitable, depending on configuration<\/span><\/td>\n<td><span style=\"font-weight: 400;\">Suitable, depending on configuration<\/span><\/td>\n<td><span style=\"font-weight: 400;\">Strong fit<\/span><\/td>\n<\/tr>\n<tr>\n<td><b>Site preparation and subdivisions<\/b><\/td>\n<td><span style=\"font-weight: 400;\">Strong fit<\/span><\/td>\n<td><span style=\"font-weight: 400;\">Strong fit<\/span><\/td>\n<td><span style=\"font-weight: 400;\">Suitable, depending on configuration<\/span><\/td>\n<\/tr>\n<tr>\n<td><b>Finish grading<\/b><\/td>\n<td><span style=\"font-weight: 400;\">Suitable, depending on configuration<\/span><\/td>\n<td><span style=\"font-weight: 400;\">Suitable, depending on configuration<\/span><\/td>\n<td><span style=\"font-weight: 400;\">Suitable, depending on configuration<\/span><\/td>\n<\/tr>\n<tr>\n<td><b>Snow removal<\/b><\/td>\n<td><span style=\"font-weight: 400;\">Suitable, depending on configuration<\/span><\/td>\n<td><span style=\"font-weight: 400;\">Suitable, depending on configuration<\/span><\/td>\n<td><span style=\"font-weight: 400;\">Suitable, depending on configuration<\/span><\/td>\n<\/tr>\n<tr>\n<td><b>Demanding traction<\/b><\/td>\n<td><span style=\"font-weight: 400;\">Consider another configuration or machine<\/span><\/td>\n<td><span style=\"font-weight: 400;\">Consider another configuration or machine<\/span><\/td>\n<td><span style=\"font-weight: 400;\">Strong fit<\/span><\/td>\n<\/tr>\n<tr>\n<td><b>Machine-controlled grading<\/b><\/td>\n<td><span style=\"font-weight: 400;\">Suitable, depending on configuration<\/span><\/td>\n<td><span style=\"font-weight: 400;\">Suitable, depending on configuration<\/span><\/td>\n<td><span style=\"font-weight: 400;\">Suitable, depending on configuration<\/span><\/td>\n<\/tr>\n<tr>\n<td><b>General-purpose versatility<\/b><\/td>\n<td><span style=\"font-weight: 400;\">Strong fit<\/span><\/td>\n<td><span style=\"font-weight: 400;\">Strong fit<\/span><\/td>\n<td><span style=\"font-weight: 400;\">Suitable, depending on configuration<\/span><\/td>\n<\/tr>\n<tr>\n<td><b>Higher production capacity<\/b><\/td>\n<td><span style=\"font-weight: 400;\">Consider another configuration or machine<\/span><\/td>\n<td><span style=\"font-weight: 400;\">Consider another configuration or machine<\/span><\/td>\n<td><span style=\"font-weight: 400;\">Strong fit<\/span><\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<p>&nbsp;<\/p>\n<p><span style=\"font-weight: 400;\">For the Cat 140M, &#8220;another configuration&#8221; means AWD. For the 670G, it means a 672G or 772G.<\/span><\/p>\n<h2><span class=\"ez-toc-section\" id=\"Traction_Blade_Pull_and_Real-World_Productivity\"><\/span><b>Traction, Blade Pull, and Real-World Productivity<\/b><span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p><span style=\"font-weight: 400;\">Engine power is only the start. Net horsepower is measured at the flywheel. What reaches the ground depends on the gear, the weight over the driven wheels, and how much grip the surface offers. Both OEMs also tune power by gear: the 772G&#8217;s Tier 3 table runs from 220 hp in first gear to 270 hp in seventh, so quoting a single &#8220;hp&#8221; figure flatters one machine or another.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Think of four separate things: engine power, usable power at the wheels, weight over the driven wheels, and the grip the surface allows. Weight and grip cap how much of the engine&#8217;s power becomes pull. Past that limit, the wheels spin.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Driven wheels change the traction side. Cat&#8217;s specalog shows AWD lifting blade pull from 21,766 lb to 31,370 lb at base weight, about 44 percent. Deere&#8217;s 772G rates 49,500 lb against the 670G&#8217;s 34,173 lb at maximum weight, about 45 percent more. Those gaps include differences in weight and power, not just drivetrain, and they are calculated ratings, not field measurements. The AWD hardware has a cost: Cat says it raises gross engine power by up to 35 hp to offset the parasitic load, so net power holds constant.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">We found no trustworthy independent test that measures completed yards per hour for these three machines. So we cannot say a six-wheel-drive grader always finishes sooner. What we can say is that production on a light blading pass is limited by speed and pass count, while production in heavy material is limited by traction. Soil, moisture, tires, ballast, cut depth, and operator skill can outweigh a 10,000 lb difference on a spec sheet.<\/span><\/p>\n<h2><span class=\"ez-toc-section\" id=\"Operator_Controls_Precision_and_Technology\"><\/span><b>Operator Controls, Precision, and Technology<\/b><span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p><span style=\"font-weight: 400;\">The 140M puts steering, gear selection, and blade functions on two joysticks, with no steering wheel. Deere G-Series machines use a steering wheel on every model, with levers on G units and fingertip or dual-joystick controls on GP units. The Cat vs. Deere grader debate often comes down to this, and Cat&#8217;s own claim of reduced hand movement is a manufacturer comparison, not an independent test. Operators who learned on levers may need time on joysticks, and the reverse is also true. That is a practical consideration, not a documented productivity penalty.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Both brands offer shift automation: the 140M has a programmable Autoshift option, and Deere&#8217;s Auto-Shift PLUS lets operators work without the inching pedal. Technology varies by build year. The 140M carries Cat Messenger diagnostics and Product Link readiness. Deere units use a diagnostic LCD monitor and JDLink in supported countries. Grade-control kits can be retrofitted to older machines, but we have no verified retrofit pricing. Get quotes for the exact serial number before counting it as a saving.<\/span><\/p>\n<h2><span class=\"ez-toc-section\" id=\"Used_Grader_Ownership_Costs_and_Common_Buying_Risks\"><\/span><b>Used Grader Ownership Costs and Common Buying Risks<\/b><span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p><span style=\"font-weight: 400;\">Hours alone cannot tell you a machine&#8217;s remaining life. A county-owned 2009 140M offered at a platform showed about 17,970 hours with a documented powertrain repair at 13,256 hours. That record is more useful than the hour meter. Duty cycle, idle time, and maintenance quality matter more than the model badge, and we have no comparable evidence that any of the three lasts longer.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Inspect the systems that decide uptime: engine and fuel system, transmission, tandem and final drives, circle and drawbar wear, cutting edges, hydraulic pumps, cylinders and hoses, the articulation joint, front axle and wheel-lean parts, tires, and electronics. Cat&#8217;s specalog highlights a modular rear axle and top-adjust drawbar wear strips. Deere lists an optional sealed premium circle and grouped service points. Those features cut service time when intact, but we found no verified failure rankings, repair costs, or component-life figures for any of the three, and we will not invent them.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Weigh these cost components for each machine you consider:<\/span><\/p>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Purchase price and transport.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Immediate repairs: tires, cutting edges, circle and drawbar wear, hydraulic leaks.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Scheduled service and the cost of parts for that serial number.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Fuel.

Confirm your nearest dealer, parts lead times for the serial number, technician familiarity with that model year, and what an independent shop can service. Do not assume either brand has the stronger network where you work.<\/span><\/p>\n<p><b>Emissions.<\/b><span style=\"font-weight: 400;\"> The 140M&#8217;s C7 is rated Tier 3 in Cat&#8217;s specalog. Deere&#8217;s brochures show Final Tier 4 machines carrying a diesel exhaust fluid tank, while the Tier 3 and Tier 2 versions do not. EPA&#8217;s emission standards reference guide sets out the tiers, but state and local rules vary, so check your jurisdiction.<\/span><\/p>\n<p><b>Market evidence.<\/b><span style=\"font-weight: 400;\"> Completed prices we found span a wide range: a 2009 Cat 140M VHP sold for $58,000 at a platform (October 30, 2025), and a 2010 140M for $67,100 at Purple Wave (July 31, 2025). A 2018 John Deere 670G sold for $62,000 (July 3, 2025) and a 2016 for $73,000 (January 8, 2026). A 2013 John Deere 772G with 7,213 hours sold for $67,100 and a 2012 772GP with 11,179 hours for $60,500 in mid-2025, while a 2018 772G reached $155,100 that June. These are not matched pairs; hours, fees, attachments, and location differ.<\/span><\/p>\n<p><b>Resale.<\/b><span style=\"font-weight: 400;\"> Year, hours, condition, configuration, records, attachments, and local demand all move value. We found no evidence that either brand holds value better in every region, so ask local auctioneers what they see. A short contract favors a cheaper machine. A long-term fleet position favors a documented, well-supported one.<\/span><\/p>\n<h2><span class=\"ez-toc-section\" id=\"Comparing_Real_Used_Cat_140M_Buying_Options\"><\/span><b>Comparing Real Used Cat 140M Buying Options<\/b><span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p><span style=\"font-weight: 400;\">Two machines in our inventory show why you should compare condition evidence, not just model and year.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">The<\/span><a href=\"https:\/\/usedmotorgrader.com\/caterpillar-140m-b9d00263\"> <span style=\"font-weight: 400;\">2008 Caterpillar 140M<\/span><\/a><span style=\"font-weight: 400;\"> has 9,896 hours, serial number B9D00263, and a Houston, Texas location marked in transit.
