Models by Size<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p>Caterpillar categorises <strong>Caterpillar track excavators by size<\/strong>. Generally, the higher the model number the heavier the machine. Names and availability can change from one generation to the next, and are variable by market, so this is a map, not a catalog.<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Mini excavators:<\/strong> 300.9D, 301.5, 302, 303, 304, 305 and 306 series. Cat&#8217;s mini range starts near 2,061 lb (300.9D) and passes 21,000 lb (309 CR).<\/li>\n\n\n\n<li><strong>Small excavators:<\/strong> 313, 315, 317 and 319.<\/li>\n\n\n\n<li><strong>Medium excavators:<\/strong> 320, <a href=\"https:\/\/www.micoequipment.com\/listings\/for-sale\/track-excavators\/caterpillar-323FL\/229\">323<\/a>, 325, 326, 330 and 335.<\/li>\n\n\n\n<li><strong>Large excavators:<\/strong> 336, 340, 350, 352, 374 and 395.<\/li>\n\n\n\n<li><strong>Special-purpose:<\/strong> wheel excavators, demolition excavators and long-reach configuration.<\/li>\n<\/ul>\n\n\n\n<p>When consumers compare excavators, they are typically sorted by size, and that&#8217;s how <strong>CAT&#8217;s mini, small, medium and large excavators<\/strong> are usually classified.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"CAT_Excavator_Sizes_and_Weights_Chart\"><\/span>CAT Excavator Sizes and Weights Chart<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p>Here is a <strong>CAT excavator sizes chart<\/strong> for six common models. Figures are Caterpillar&#8217;s listed operating weights for the standard configuration of the current version.<\/p>\n\n\n\n<figure class=\"wp-block-table is-style-stripes\"><table class=\"has-fixed-layout\"><tbody><tr><td><strong>Model<\/strong><\/td><td><strong>Size class<\/strong><\/td><td><strong>Operating weight<\/strong><\/td><td><strong>Typical application<\/strong><\/td><\/tr><tr><td>CAT 301.5<\/td><td>Mini<\/td><td>3,913 lb (1,775 kg)<\/td><td>Landscaping and utility work<\/td><\/tr><tr><td>CAT 305 CR<\/td><td>Mini<\/td><td>12,688 lb (5,754 kg)<\/td><td>Compact construction<\/td><\/tr><tr><td>CAT 315<\/td><td>Small<\/td><td>34,000 lb (15,400 kg)<\/td><td>Site preparation and excavation<\/td><\/tr><tr><td>CAT 320<\/td><td>Medium<\/td><td>49,800 lb (22,600 kg)<\/td><td>General construction and earthmoving<\/td><\/tr><tr><td>CAT 336<\/td><td>Large<\/td><td>81,100 lb<\/td><td>Heavy excavation, larger projects<\/td><\/tr><tr><td>CAT 395<\/td><td>Large<\/td><td>207,400 lb (94,100 kg)<\/td><td>High-volume earthmoving, mining-related work<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<p>These <strong>CAT excavator sizes and weights<\/strong> shift with the boom, stick, track shoes, counterweight and bucket. Caterpillar&#8217;s own 2016 release listed an early Next Generation 336 at 75,800 lb, so the same model number can carry different figures. For a used machine, check the exact year and configuration.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"CAT_320_Excavator_Models_Explained\"><\/span>CAT 320 Excavator Models Explained<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p>The 320 is the one most buyers ask about, and it shows why model families matter. A family is a model line. A listing is one specific machine with its own year, hours and setup.<\/p>\n\n\n\n<p>The <a href=\"https:\/\/www.cat.com\/en_AU\/products\/new\/equipment\/excavators\/medium-excavators\/126532.html\"><strong>CAT 320 excavator specifications<\/strong><\/a> have changed across generations. The 320D3 is listed at 46,300 lb, 123 hp and a 20.8 ft maximum digging depth. The current Cat 320 is listed at 49,800 lb, 172 hp and 22 ft. Older <strong>CAT 320C<\/strong> machines sit around 48,000 lb in published spec charts.<\/p>\n\n\n\n<p><strong>CAT 320 vs 320CL<\/strong><\/p>\n\n\n\n<p>The letters carry meaning. The &#8220;C&#8221; points to the generation. The &#8220;L&#8221; generally means a long undercarriage, which gives longer tracks and a steadier base. A <strong><a href=\"https:\/\/www.micoequipment.com\/listings\/for-sale\/track-excavators\/caterpillar-320CL\/224\">CAT 320CL excavator<\/a><\/strong> will usually weigh more than a standard 320C and can handle heavier lifting. Always confirm the setup on the machine in front of you.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Old_Caterpillar_Excavator_Models_List\"><\/span>Old Caterpillar Excavator Models List<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p>The <strong>old Caterpillar excavator models list<\/strong> most buyers see on the used market includes the 312, 315, 320C and 320D, 325, 330C and 330D, 345 and 365 generations. The <a href=\"https:\/\/www.micoequipment.com\/listings\/for-sale\/track-excavators\/caterpillar-329EL\/237\">329EL<\/a> and 336EL also turn up often in the <strong>used Caterpillar excavator models list<\/strong> of dealers and auctions.<\/p>\n\n\n\n<p>Letter suffixes (C, D, E, F) mark generations. Newer &#8220;Next Generation&#8221; machines drop the letter. We are not putting production years on whole families here, because a family spans several years and the real year sits with the individual machine.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Caterpillar_Excavator_Models_by_Year\"><\/span>Caterpillar Excavator Models by Year<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p>A <strong>Caterpillar excavator models list by year<\/strong> can mislead, since model generation and build year are two separate facts. To find the year of a specific machine:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Read the <a href=\"https:\/\/www.fridayparts.com\/blog\/what-year-is-my-caterpillar\"><strong>CAT excavator year and serial number<\/strong><\/a> (the product identification number) on the frame plate.<\/li>\n\n\n\n<li>Ask the seller for machine records and paperwork.<\/li>\n\n\n\n<li>Have a Cat dealer confirm the build date from the serial number if the paperwork is thin.<\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Who_Buys_Used_CAT_Excavators_and_Where_They_Work\"><\/span>Who Buys Used CAT Excavators and Where They Work<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p>Buyers come from a few groups. Landscapers and utility crews pick mini machines for tight sites. General contractors and site developers lean toward the 315 to 330 range for trenching, foundations and road work. Quarries, mass-excavation firms and fleet managers look at the 336 and above, where volume matters more than size limits. Rental fleets buy all three.<\/p>\n\n\n\n<p>Most of them look at used machines for the same reasons: lower cash outlay, shorter wait than a factory order, and a model with a known parts supply.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"New_vs_Used_CAT_Excavators_Price_Difference\"><\/span>New vs Used CAT Excavators: Price Difference<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p>New machines cost real money. <a href=\"https:\/\/compact.miltoncat.com\/mini-excavators?hsLang=en\"><strong>Milton Cat&#8217;s mini excavator<\/strong><\/a> page lists MSRP starting at $45,535 for the 302 CR, $80,206 for the 305 CR and $93,413 for the 306 CR. Larger models are quoted on request.<\/p>\n\n\n\n<p>Used prices depend on year, hours, size, undercarriage wear and location, so there is no honest single range. A used machine has already taken the early depreciation, which is where most value loss tends to happen. Ask for a current quote on the exact unit.<\/p>\n\n\n\n<p>Mico Equipment sells its used machines as they came in. They are described as in good condition. If a buyer wants an inspection or a report, that can be requested and arranged.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"How_to_Choose_the_Right_Used_CAT_Excavator\"><\/span>How to Choose the Right Used CAT Excavator<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p>Compare machines on these points, not on model number alone:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Digging depth<\/strong> and reach for your jobs.
