🔧 Product Highlights

• Direct OEM Replacement — Bobcat 6667987 / Nippon Denso 228000-5740 12V 10T 1.4kW CW OSGR Starter for Bobcat Kubota D722 / D1005 Powered Skid Steers and Mini Track Loaders: Drop-in fit for Bobcat 453, 463, 553, 653, 751, S70 skid steer loaders and MT50, MT52, MT55 mini track loaders — matching original Bobcat 6667987 / Denso 228000-5740 12V 10T 1.4kW clockwise OSGR starter specifications for the Kubota D722D / D1005B small diesel engine platform
• OSGR (Offset Gear Reduction) Starter Design — High Cranking Torque for Reliable Cold-Weather Starting in the Kubota D722 / D1005 Small Diesel Engine: The Bobcat 6667987 uses an OSGR (Offset Gear Reduction) starter design — the gear reduction mechanism increases cranking torque output relative to direct-drive starters of equivalent size, enabling reliable engine cranking under cold-weather conditions and high-load starts. OSGR starters are the standard design for small diesel engines in the sub-25HP class, including the Kubota D722 and D1005 used across Bobcat compact and mini equipment. Key specifications: 10-tooth pinion, 38.4mm / 1.512 inch pinion OD, 11.0mm unthreaded mounting holes (both), DE housing reference 228400-5740
• Bobcat 453 / 463 / S70 — The World’s Most Compact Skid Steers and the Standard Choice for Confined-Space Landscaping, Nursery, and Urban Access Work: The Bobcat 453, 463, and S70 are Bobcat’s smallest skid steer loaders — designed for access in confined spaces where larger skid steers and track loaders cannot operate. These compact Bobcat skid steers are the go-to machines for landscaping contractors, nurseries, greenhouse operators, urban construction in tight sites, and interior demolition work. Their compact footprint and Kubota diesel power make them indispensable in the rental fleet and owner-operator compact equipment segment
• Bobcat MT50 / MT52 / MT55 — Bobcat’s Mini Track Loaders for Ultra-Confined Landscape and Hardscape Access: The Bobcat MT50, MT52, and MT55 are Bobcat’s mini track loader lineup — ultra-compact rubber-tracked machines designed for the tightest-access landscaping, hardscaping, and residential construction applications. Mini track loaders are the fastest-growing segment of the compact equipment market in North America — driven by demand from landscaping contractors, pavers, and residential builders who need tracked traction and zero-turn manoeuvrability in confined back-garden, courtyard, and urban site conditions. The MT-series machines use the Kubota D722 / D1005 diesel, requiring the same Bobcat 6667987 starter as the larger skid steer models
• Kubota D722 / D1005 in Bobcat Equipment — Kubota’s Sub-25HP Small Diesel Platform as Bobcat’s OEM Engine of Choice for Compact and Mini Equipment: Bobcat selected Kubota’s D722 and D1005 small-displacement diesel engines as the OEM power unit for its most compact skid steer and mini track loader models — leveraging Kubota’s proven reliability, compact dimensions, and cold-start capability in the demanding high-cycle duty of compact equipment rental and owner-operator use. This OEM engine relationship between Bobcat and Kubota means Bobcat 6667987 starters cross-reference directly to Nippon Denso 228000-5740 / 228000-5741, simplifying parts identification across both Bobcat and Kubota dealer channels
• Bobcat — The World’s Most Recognised Skid Steer Brand and the Original Inventor of the Modern Skid Steer Loader: Bobcat (now Doosan Bobcat, a Doosan Infracore / HD Hyundai company) is the brand that invented and commercialised the modern skid steer loader in the 1960s — and remains the most recognised and widely owned skid steer brand in the world. Bobcat skid steers and compact track loaders are the dominant choice for landscaping, construction, agriculture, and rental applications across North America, Europe, and Australia, with an enormous global installed base driving sustained demand for OEM and aftermarket replacement parts including starters
