Kubota G1700, G1800, G1900, G2000 Workshop Manual – 422 Pages of Factory Meat

You bought a Kubota G1700 or one of its siblings because they’re built to run. But when the engine won’t start, the transmission grinds, or the brake pedal goes to the floor, guesswork costs you time and money. I’ve seen guys split the case on a G1900 because they thought the noise was in the rear axle, only to find a failed PTO bearing they could have fixed without pulling the whole drivetrain. That’s why you need this Kubota G1700, G1800, G1900, G2000 Workshop Manual – 422 pages of factory procedure, not aftermarket fluff. Every spec came off the same line as your machine. No rewrites, no guesswork.

Engine Section: D950 and D1105 – What’s Inside

The ENGINE chapter covers both the D950 and D1105 diesels used across these models. You get the piston ring gaps, valve clearances, injector pump timing, and the exact head bolt torque sequence. The manual tells you to check the valve recess before you reinstall the head – skip that step and you’ll be back in the shop before the mower finishes one lawn. Need the compression pressure spec? It’s listed right there. This isn’t a generic Chilton book; this is the same document the dealer techs used in 1989.

If you’re working on a G1800 with a weird knock, the troubleshooting tree in the ENGINE section will walk you through cylinder cutout tests and bearing clearance inspections. I’ve used it myself to isolate a wrist pin noise in under an hour.

Transmission and Rear Axle: Splitting the Case the Right Way

The TRANSMISSION AND REAR AXLE chapter is where most DIY guys mess up. The manual gives you the factory procedure for removing the differential carrier, setting the ring gear backlash, and torquing the axle housing bolts. The shim selection chart is printed in the book – don’t try to reuse old shims without measuring. The section also includes a thorough explanation of the hydrostatic transmission for models that have it. You’ll find the charge pressure spec and the troubleshooting for slippage. This is not the place to use an aftermarket PDF that might have the wrong bearing preload.

For those new to transmissions, the manual also explains the gear train layout – it’s like having a schematic for a Manual Transmission right in your hands.

Brake System: Factory Adjustment Procedure

The BRAKE chapter covers both the mechanical drum brakes and the hydraulic brake system used on later models. The adjustment specs are given for pedal free travel and lining thickness. You’ll also see the bleeding procedure – it’s not the same as a car. The manual warns you to check the brake drum runout with a dial indicator before you reinstall the wheel. I’ve seen guys skip that, and then wonder why the pedal pulses. The factory brake shoe arc grind spec is in there too – you won’t find that in a Haynes manual.

This chapter is short – maybe 15 pages – but every page is necessary. Don’t skip the section on brake linkage adjustment; it will save you from pulling the whole dash apart later.

Electrical System: Tracing the Harness Without Burning It Down

ELECTRICAL SYSTEM is the one chapter I see people ignore until the mower won’t crank. The manual includes wiring diagrams for the G1700, G1800, G1900, and G2000 – separate diagrams, not one generic mess. You get the starter circuit, charging system, safety interlock switches, and PTO solenoid wiring. I’ve fixed a no-start on a G2000 by following the voltage drop test procedure from this book. The fuse location and amperage are listed. If you’re adding aftermarket lights or a hour meter, the manual shows you where to tap in without messing up the factory harness. Trust me, an electrical short on a diesel mower can kill the ECU (if equipped) or fry the alternator. This book keeps you safe.

Source Authenticity: OEM Kubota, Not a Copy

This is an original OEM workshop manual, part number 9789710835, printed August 1989. It’s the same document that came with the mower when it was new – not a scanned version with missing pages, not a third-party rewrite that guessed the torque values. The copyright is Kubota Corporation 1990. I’ve bought aftermarket manuals that list the wrong transmission oil capacity, and you know what that costs you? A fried transmission. This one is correct because it came from the factory. If you want to fix your Kubota right, you start with the factory book.

Is This Manual Worth 422 Pages?

Short answer: yes. The book is divided into two main parts – MECHANISM and DISASSEMBLING AND SERVICING. The mechanism section explains how each system functions before you touch a wrench. The servicing section gives you the factory tolerances, torque specs, and step-by-step procedures. Every section includes troubleshooting charts, removal and installation sequences, and special tool lists. The page count is 422 because every spec is printed – not because the publisher added fluff.

If you’re comfortable with a service manual and have basic mechanic skills, this book will get you through a full engine rebuild, transmission overhaul, or brake job. If you’re a beginner, the mechanism section teaches you how the thing works first. I wouldn’t recommend this for someone who’s never turned a wrench, but if you’ve done an oil change and can read a torque wrench, you’re good.

The manual covers the G1700, G1800, G1900, and G2000 mower models. It does NOT cover the older G-series with different engines – verify your model number before buying.

FAQ – Four Questions You’ll Ask

Does this manual cover the G1800 diesel model?

Yes. The ENGINE section includes the D1105 engine used in the G1800, with all injection pump and valve specs. The G1800 is listed on the cover.

What torque values are listed for the front axle?

The FRONT AXLE chapter gives the kingpin preload torque and the wheel bearing nut adjustment. I don’t have the page number memorized, but it’s in the servicing spec table at the start of that chapter.

Are wiring diagrams included for all four models?

Yes, the ELECTRICAL SYSTEM chapter has separate wiring diagrams for the G1700, G1800, G1900, and G2000. They are not simplified – they show every wire color and connector. I used the G1900 diagram to trace a faulty safety switch on a friend’s mower and had it running in 20 minutes.

Is this the full factory manual or a summary?

This is the complete workshop manual, 422 pages, as published by Kubota in 1989. It includes both mechanism theory and detailed disassembly/servicing procedures. No pages are missing. The part number is 9789710835.

You’ve got the mower. Now get the factory specs and stop wasting time on forums. Access the Factory Manual from AutoRepairManuals and keep it on your workbench. I’ve seen too many good machines ruined by wrong torque values and missing steps. This book is your insurance.
