With over 100 registered patents and utility models, we don't build standard machines \u2013 we develop practical solutions that make construction sites worldwide faster, more efficient, and more environmentally friendly.<\/p>\n  <\/div>\n\n  <!-- KACHEL 1: Vor 1983 -->\n  <div class=\"stehr-bento-card bento-half\">\n    <div class=\"bento-icon-header\">\n      <div class=\"bento-icon\"><i class=\"fa-solid fa-route\"><\/i><\/div>\n      <div class=\"stehr-date-badge\">Before 1983<\/div>\n    <\/div>\n    <h3>Apprenticeship and Traveling Years<\/h3>\n    <p>After completing his training as an agricultural machinery mechanic, the young J\u00fcrgen Stehr was drawn out into the world. During his traveling years, he gained valuable practical experience outside his Hessian homeland. This period shaped his inexhaustible inventive spirit and his eye for unconventional solutions that prove themselves directly in practice.<\/p>\n  <\/div>\n\n  <!-- KACHEL 2: 1983 -->\n  <div class=\"stehr-bento-card bento-half\">\n    <div class=\"content-img-wrapper\">\n      <img decoding=\"async\" src=\"https:\/\/www.stehr.com\/wp-content\/uploads\/2026\/09\/555026780_24824888517146707_6493455457642249665_n.jpg\" alt=\"Stehr Garage 1983\">\n    <\/div>\n    <div class=\"bento-icon-header\">\n      <div class=\"bento-icon\"><i class=\"fa-solid fa-warehouse\"><\/i><\/div>\n      <div class=\"stehr-date-badge\">1983<\/div>\n    <\/div>\n    <h3>Birth in the Garage<\/h3>\n    <p>J\u00fcrgen Stehr took the leap into self-employment and founded his company in a small garage in Storndorf, a district of Schwalmtal. With minimal resources but immense passion, the first prototypes were created right here.<\/p>\n  <\/div>\n\n  <!-- KACHEL 3: 1987 -->\n  <div class=\"stehr-bento-card bento-half\">\n    <div class=\"bento-icon-header\">\n      <div class=\"bento-icon\"><i class=\"fa-solid fa-hammer\"><\/i><\/div>\n      <div class=\"stehr-date-badge\">1987<\/div>\n    <\/div>\n    <h3>The Mini Excavator Breakthrough<\/h3>\n    <p>When the first mini excavators emerged at the end of the 1980s, established large corporations still ridiculed them as \"toys\" and refused to manufacture suitable attachments. J\u00fcrgen Stehr seized the initiative: without further ado, he developed robust buckets for mini excavators himself, along with the accompanying, revolutionary hydraulic breaker. A new market niche was filled.<\/p>\n  <\/div>\n\n  <!-- KACHEL 4: 1989 -->\n  <div class=\"stehr-bento-card bento-half\">\n    <div class=\"bento-icon-header\">\n      <div class=\"bento-icon\"><i class=\"fa-solid fa-layer-group\"><\/i><\/div>\n      <div class=\"stehr-date-badge\">1989<\/div>\n    <\/div>\n    <h3>Vibration-Free Add-On Compactor<\/h3>\n    <p>Stehr revolutionized compaction technology in inner-city civil engineering with the first hydraulic add-on compactor for completely vibration-free compaction. Because 100 percent of the energy is directed vertically into the ground, damage to surrounding buildings is consistently avoided. The highly efficient units are designed for flexible operation on wheel loaders, excavators, and tractors.<\/p>\n  <\/div>\n\n  <!-- KACHEL 5: Mitte der 1990er -->\n  <div class=\"stehr-bento-card bento-half\">\n    <div class=\"bento-icon-header\">\n      <div class=\"bento-icon\"><i class=\"fa-solid fa-tractor\"><\/i><\/div>\n      <div class=\"stehr-date-badge\">Mid-1990s<\/div>\n    <\/div>\n    <h3>Focus on Tractors & Fendt Vario<\/h3>\n    <p>Stehr was the first to recognize the enormous potential of agricultural tractors in construction. The key to success was the continuously variable Fendt Vario drive. J\u00fcrgen Stehr combined his heavy-duty special trenchers and compactors with this drive system. This was the only way to smoothly transfer full PTO speed to the ground at minimal, infinitely variable creep speeds. The tractor became a fully-fledged construction machine.<\/p>\n  <\/div>\n\n  <!-- KACHEL 6: 2001 -->\n  <div class=\"stehr-bento-card bento-half\">\n    <div class=\"bento-icon-header\">\n      <div class=\"bento-icon\"><i class=\"fa-solid fa-gear\"><\/i><\/div>\n      <div class=\"stehr-date-badge\">2001<\/div>\n    <\/div>\n    <h3>The Conical Manhole Cover Cutter<\/h3>\n    <p>Another stroke of genius: Stehr invented the manhole cover cutter with a globally unique conical milling head. The system enables fast, precisely fitting, and clean cutting out of manhole covers during road rehabilitation in absolute record time.<\/p>\n  <\/div>\n\n  <!-- KACHEL 7: 2012 -->\n  <div class=\"stehr-bento-card bento-half\">\n    <div class=\"bento-icon-header\">\n      <div class=\"bento-icon\"><i class=\"fa-solid fa-leaf\"><\/i><\/div>\n      <div class=\"stehr-date-badge\">2012<\/div>\n    <\/div>\n    <h3>Dust-Free Soil Stabilization<\/h3>\n    <p>Environmental and health protection came into focus: Stehr launched a groundbreaking invention for completely dust-free soil stabilization. Binders such as lime or cement are mixed directly into the soil without any dust generation \u2013 a crucial advantage for construction sites near residential areas.<\/p>\n  <\/div>\n\n  <!-- KACHEL 8: 2013 -->\n  <div class=\"stehr-bento-card bento-half\">\n    <div class=\"bento-icon-header\">\n      <div class=\"bento-icon\"><i class=\"fa-solid fa-road\"><\/i><\/div>\n      <div class=\"stehr-date-badge\">2013<\/div>\n    <\/div>\n    <h3>The All-In-One Road Maintenance System<\/h3>\n    <p>The logical next step: Stehr revolutionized road construction with an intelligent combination system on a single tractor. While the heavy rear grader blade tears up and profiles the path, the front plate compactor compacts the material in the very same pass. This eliminates the need for three separate construction machines.<\/p>\n  <\/div>\n\n  <!-- KACHEL 9: 2023 -->\n  <div class=\"stehr-bento-card bento-half\">\n    <div class=\"content-img-wrapper\">\n      <img decoding=\"async\" src=\"https:\/\/www.stehr.com\/wp-content\/uploads\/2026\/09\/IMG_9552.jpg\" alt=\"Stehr Special Machinery 2023\">\n    <\/div>\n    <div class=\"bento-icon-header\">\n      <div class=\"bento-icon\"><i class=\"fa-solid fa-award\"><\/i><\/div>\n      <div class=\"stehr-date-badge\">2023<\/div>\n    <\/div>\n    <h3>40 Years of Stehr Baumaschinen<\/h3>\n    <p>The company celebrated its 40th anniversary.
