Compact Class<\/strong> The caterpillar mini excavator lineup, including the CAT 304 and CAT 305, covers the smallest working sizes in the range. These machines fit through gates, work in tight urban lots, and handle utility trenching, landscaping, and small demolition without tearing up the surrounding ground.<\/p>\n\n\n\n<p><strong>2. Mid-Size Class<\/strong> This is where most general construction work happens. The 320C Caterpillar excavator and its successors, along with the Caterpillar 323 excavator, fall into this class. You&#8217;ll see these on road jobs, commercial site prep, and pipeline work, versatile enough for digging, grading, and material handling in one package.<\/p>\n\n\n\n<p><strong>3. Large Class<\/strong> This includes CAT 329 and CAT 330 families sit here. A CAT 329 excavator for sale is generally used by a buyer who needs heavier lifting, deeper excavation, or bigger bucket capacity for mass earthmoving, mining support, or large demolition work. Exact operating weight varies by configuration and attachment.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Popular_Caterpillar_Excavator_Models\"><\/span><strong>Popular Caterpillar Excavator Models<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p>These CAT models are commonly encountered in the used equipment market and cover several of the size classes most buyers look for.<\/p>\n\n\n\n<ol start=\"1\" class=\"wp-block-list\">\n<li><a href=\"https:\/\/www.micoequipment.com\/listings\/for-sale\/track-excavators\/caterpillar-304E-CR\/134\" type=\"link\" id=\"https:\/\/www.micoequipment.com\/listings\/for-sale\/track-excavators\/caterpillar-304E-CR\/134\"><strong>CAT 304 Excavator<\/strong>:<\/a> the go-to compact option for operators who need mobility and maneuverability over raw digging power.<\/li>\n\n\n\n<li><strong><a href=\"https:\/\/www.micoequipment.com\/listings\/for-sale\/track-excavators\/caterpillar-320CL\/224\" type=\"link\" id=\"https:\/\/www.micoequipment.com\/listings\/for-sale\/track-excavators\/caterpillar-320CL\/224\">CAT 320 Series (320C \/ 320D)<\/a><\/strong>: a construction industry depend for decades, backed by CAT&#8217;s established dealer and parts network.<\/li>\n\n\n\n<li><strong><a href=\"https:\/\/www.micoequipment.com\/listings\/for-sale\/track-excavators\/caterpillar-323FL\/229\" type=\"link\" id=\"https:\/\/www.micoequipment.com\/listings\/for-sale\/track-excavators\/caterpillar-323FL\/229\">Caterpillar 323 Excavator<\/a><\/strong>: it builds on the 320 with improved hydraulic efficiency and cab comfort.<\/li>\n\n\n\n<li><strong><a href=\"https:\/\/www.micoequipment.com\/listings\/for-sale\/track-excavators\/caterpillar-329EL\/237\" type=\"link\" id=\"https:\/\/www.micoequipment.com\/listings\/for-sale\/track-excavators\/caterpillar-329EL\/237\">CAT 329 Series (329D \/ 329E \/ 329F)<\/a><\/strong>: it\u2019s the workhorse choice when a job needs more digging depth and lift capacity without stepping up to mining scale equipment.<\/li>\n<\/ol>\n\n\n\n<p>Between them, these four groups cover most of what contractors actually buy on the used market.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Why_Choose_a_CAT_Excavator_for_Your_Job\"><\/span><strong>Why Choose a CAT Excavator for Your Job<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p>Caterpillar excavators are widely used in construction, and a few practical factors explain why buyers keep coming back to the brand.<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>CAT&#8217;s established dealer and parts network can make sourcing replacement parts and service support easier, especially in the US.<\/li>\n\n\n\n<li>Hydraulic systems are generally straightforward to service, which matters when a machine is running hard on a tight schedule.<\/li>\n\n\n\n<li>CAT resale value tends to hold up reasonably well for well maintained units, which matters when the machine eventually gets traded or sold.<\/li>\n<\/ul>\n\n\n\n<p><\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"What_to_actually_inspect_on_a_Used_Caterpillar_Excavator\"><\/span><strong>What to actually inspect on a Used Caterpillar Excavator<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p>Before committing to any <a href=\"https:\/\/www.micoequipment.com\/listings\/for-sale\/track-excavators\" type=\"link\" id=\"https:\/\/www.micoequipment.com\/listings\/for-sale\/track-excavators\">used CAT excavator for sale<\/a>, walk the machine yourself or have someone who knows excavators do it for you.

A machine with 8,000 hours that&#8217;s been serviced on schedule can outlast a 4,000 hour machine that sat neglected. What actually matters is how those hours were accumulated, the application it worked, how consistently it was maintained, and the condition of the undercarriage and hydraulics today. Use hours to narrow down your shortlist, then let the physical inspection and maintenance records make the final call.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"How_Much_Does_a_Used_Caterpillar_Excavator_Cost\"><\/span><strong>How Much Does a Used Caterpillar Excavator Cost?<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p>Prices for <a href=\"https:\/\/www.micoequipment.com\/listings\/for-sale\/track-excavators\" type=\"link\" id=\"https:\/\/www.micoequipment.com\/listings\/for-sale\/track-excavators\">used CAT excavators<\/a> can be change based on these handful of factors:<\/p>\n\n\n\n<ol start=\"1\" class=\"wp-block-list\">\n<li><strong>Model and size class<\/strong> compact, mid-size, and large excavators sit in different price tiers.<\/li>\n\n\n\n<li><strong>Year and hours<\/strong> \u2014 newer, lower-hour units command a premium.<\/li>\n\n\n\n<li><strong>Undercarriage condition<\/strong> \u2014 a worn undercarriage can knock thousands off the asking price, or add thousands to your first-year costs.<\/li>\n\n\n\n<li><strong>Attachments included<\/strong> \u2014 buckets, thumbs, and quick couplers add value if they&#8217;re part of the deal.<\/li>\n\n\n\n<li><strong>Location and transport<\/strong> \u2014 moving heavy equipment isn&#8217;t cheap, and distance from the seller affects the total cost.<\/li>\n<\/ol>\n\n\n\n<p>Based on current inventory and listings available on Mico Euipments, compact models like the CAT 304 have generally sold between $34,000 to $40,000, mid-size 320-series and 323-series machines from the high $58,000s into the $90,000s, and larger 329-series units anywhere from the mid $75,000s to well over $100,000 depending on year and hours. These figures shift as inventory turns over, so treat them as a starting reference and get quotes on comparable units before assuming any single price is fair.<br><br><strong>Where to Buy Used CAT Excavators<\/strong><\/p>\n\n\n\n<p>Buyers looking for used excavators for sale have more options than ever as auctions, dealer lots, and online marketplaces all move inventory, but not all of them inspect equipment the same way. Working with a dealer who inspects, services, and stands behind what they sell cuts down on the risk of buying equipment sight unseen. If you&#8217;re buying from out of state or arranging an export shipment, working with a dealer that can provide detailed machine information and documentation matters even more, since you can&#8217;t walk the lot yourself before buying.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Used_Caterpillar_Excavators_Available_at_Mico_Equipment\"><\/span><strong>Used Caterpillar Excavators Available at Mico Equipment<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p>Mico&#8217;s inventory has recently included used CAT track excavators models such as the 304E CR, 320CL, 323FL, and 329EL, with pricing and hours varying by unit.<\/p>\n\n\n\n<p>Check the full <a href=\"https:\/\/www.micoequipment.com\/listings\/for-sale\/track-excavators\" type=\"link\" id=\"https:\/\/www.micoequipment.com\/listings\/for-sale\/track-excavators\">track excavators<\/a> listing page for current availability and pricing, or contact the team directly.
