Originally published by Kubota and delivered here as an instant PDF download you can read on any device or print for the bench.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eModels covered:\u003c\/strong\u003e Kubota AT55 walk-behind tiller\u003c\/p\u003e\n\u003ch3\u003eAbout the Kubota AT55\u003c\/h3\u003e\n\u003cp\u003eThe AT55 is a walk-behind rotary tiller powered by the Kubota GS200-2T — a forced air-cooled, four-cycle, single-cylinder, side-valve gasoline engine of 201 cc (12.3 cu. in.) with a 69 × 54 mm bore and stroke, rated at 3.8 HP continuous at 1800 rpm and 5.2 HP maximum. The engine carries a maintenance-free, transistor-controlled, pointless magneto ignition system, a cyclone-type air cleaner, a horizontal butterfly-valve carburetor, a centrifugal flywheel governor, splash lubrication, and a recoil starter.\u003c\/p\u003e\n\u003cp\u003ePower runs through a pulley-and-V-belt drive to a four-speed forward, two-speed reverse auxiliary transmission (shifted by relocating the V belt on the pulleys) and a gear-and-chain main transmission (shifted by lever), with a belt-tension main clutch controlled by a deadman grip. The rotor spins 24 tines at 360 mm (14 in.) diameter for a tilling width of 660 mm (26 in.) or 920 mm (36 in.) and a maximum tilling depth of 180 mm (7 in.). These machines earned their keep on small farms and market gardens, and a great many remain in active service — which is exactly why a complete factory service reference still matters when a repair goes past routine maintenance.\u003c\/p\u003e\n\u003ch3\u003eWhat This Manual Covers\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecifications \u0026amp; dimensions:\u003c\/strong\u003e Full engine, power-transmitting-system, tiller, and rotor specifications, plus dimensioned drawings for the machine, PTO, rear hitch, and axle.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEngine mechanism:\u003c\/strong\u003e Features of the GS200-2T, intake and exhaust (cyclone air cleaner and muffler), fuel system (carburetor main and slow circuits, governor), and ignition system (magneto ignition, high-voltage generation principle, transistor magneto ignition principle, engine stop switch).\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTransmission mechanism:\u003c\/strong\u003e Construction and function of the auxiliary transmission and main transmission.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHandlebar mechanism:\u003c\/strong\u003e Handlebar and lockout device construction and function.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGeneral service section:\u003c\/strong\u003e Tiller identification, general precautions, lubricants, tightening torques, maintenance check list, check and maintenance, and special tools.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeparation:\u003c\/strong\u003e Draining transmission oil and separating the engine and transmission case for disassembly and assembling.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEngine servicing:\u003c\/strong\u003e Troubleshooting, servicing specifications, tightening torques, and checking\/disassembling\/servicing of the engine body, fuel system, ignition system, and recoil starter.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTransmission servicing:\u003c\/strong\u003e Troubleshooting, servicing specifications, and checking\/disassembling\/servicing of the auxiliary and main transmissions.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eWhy This Manual Matters\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eComponent-level repair, not just operation.\u003c\/strong\u003e This is a workshop service manual — it walks through separating the engine from the transmission case and tearing down the engine body, fuel system, ignition, recoil starter, and both transmissions.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThe reference data the job depends on.\u003c\/strong\u003e Servicing specifications, factory specifications with allowable limits, and tightening torques are included, so you can reassemble to spec rather than guess.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCarburetor and ignition detail you won't find elsewhere.\u003c\/strong\u003e The manual documents the carburetor's main and slow circuits jet by jet, and explains the transistor-controlled pointless magneto ignition — the model-specific detail generic guides don't carry.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMechanism-first structure.\u003c\/strong\u003e Each section explains construction and function before service, so you understand the system before you open it up.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLong service life, scarce documentation.\u003c\/strong\u003e These walk-behind tillers are still working machines, but factory literature is increasingly hard to find — this searchable, restored PDF puts the complete manual back in your hands.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eManual Code:\u003c\/strong\u003e 606020\u003c\/p\u003e\n\u003chr\u003e\n\u003ch3\u003eCustomers Also Bought\u003c\/h3\u003e\n\u003c!-- TODO: swap placeholder hrefs for live agmanuals.com product\/collection URLs --\u003e\n\u003cul\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/agmanuals.com\/collections\/kubota-manuals\" title=\"Kubota Manuals\"\u003eKubota Manuals\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"#\"\u003eKubota AT55 Operator's Manual\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"#\"\u003eKubota AT55 Specifications (Specs Page)\u003c\/a\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c!-- REVIEW CHECKLIST:\n1) Production years for the AT55 not stated in the manual — omitted from the H2 and About section (manual is dated Dec.
