Looking up parts for your Kubota L355SS? This 225-page factory parts catalog (OEM #12066) maps every component on the tractor to its exact Kubota part number, from crankcase internals to the 3-point hitch linkage. The engine coverage runs 56 pages of exploded views: injection pump assemblies, nozzle holders, the governor, dynamo, and oil hydraulic pump sections. Drivetrain diagrams fill another 36 pages across the differential, rear axle, and all five shift mechanisms. Exploded views and part numbers cover the full oil hydraulic circuit, and a complete wiring diagram is included. Every parts page carries REF.No., part number, quantity, and serial-number applicability columns, with country cross-references for USA, Canada, France, and Australia. It's the same data your Kubota dealer reads off the counter screen, so you can stop calling just to get a number. Bookmarked throughout, it opens on any device.

Kubota L355SS Common Problems This Manual Covers
Kubota L355SS tractor clicks and shuts off, need fuel shutoff solenoid part number p. 37
Check the Engine Stop Lever exploded view on page 37, where the idle apparatus assembly (fuel shutoff solenoid) is itemized with its part number. The assembly weighs 0.025 kgf, so confirm that figure matches your unit. Fitment varies by serial range, so verify yours in the index first.
Manual Section: Engine Stop LeverStarter solenoid or relay part number needed, tractor won't crank when key is turned p. 29
Open the Starter Section Parts on page 29. The SWITCH,MAGNET (starter solenoid) sits there at 1.29 kgf. To tell the solenoid from the relay on the same circuit, check it against the Wiring Diagram on page 131, then match part numbers to your serial range before ordering.
Manual Section: Starter Section PartsCan't identify correct fuse or fusible link part number after electrical fault p. 125
Turn to the Regulator section on page 125, where fuses (0.001 kgf each) are listed by circuit. The LINK,FUSIBLE (0.005 kgf) sits separately in the Wiring Diagram section on page 131. Work out which circuit failed first, then trace it on the wiring diagram to pull the right part number.
Manual Section: RegulatorKey switch part number needed for no-start condition, ignition unresponsive when turned p. 123
Find the Hour Meter and Switch section on page 123. The SWITCH,STARTER (key switch, 0.275 kgf) is itemized there with its part number. The Panel section on page 121 lists related switch and connector parts, so glance at it before ordering to see if you need any. Confirm serial range compatibility in the parts index.
Manual Section: Hour Meter and SwitchShuttle lever and pushpull cable part numbers for forward-only, no reverse condition p. 103
Head to the Shuttle Lever section on page 103. Both the LEVER,SHUTTLE (0.57 kgf) and CABLE,PUSHPULL (0.265 kgf) are listed there. Page 105, the Differential System section, shows whether any drivetrain parts are also at play, so review it before you order and match every part number to your serial range.
Manual Section: Shuttle LeverBattery cable and earth strap part numbers needed after no-crank diagnosis p. 127
Pull up the Battery section on page 127. The CORD,BATTERY (0.25 kgf) and CORD,EARTH (0.19 kgf) are both itemized there. The Wiring Diagram on page 131 confirms terminal type and routing. Decide whether you need the positive cord, the earth strap, or both before placing the order.
Manual Section: BatteryFrequently Asked Questions
My Kubota L355SS won't crank when I turn the key, does this manual help me find the starter solenoid part number?
Yes. The Starter Section Parts on page 29 itemize the SWITCH,MAGNET (starter solenoid) with its part number. To tell the solenoid apart from the relay on the same circuit, cross-check it against the Wiring Diagram on page 131, then match part numbers to your serial range before ordering.
My L355SS goes forward but has no reverse, what does this manual cover for the shuttle linkage?
The Shuttle Lever section on page 103 lists both the LEVER,SHUTTLE and the CABLE,PUSHPULL with their part numbers, which is where a forward-only/no-reverse fault usually traces back to. The Differential System section on page 105 shows whether any drivetrain parts are also involved, so review it before ordering and match every part number to your serial range.
After an electrical fault, can I identify the right fuse or fusible link in this L355SS manual?
Yes. The Regulator section on page 125 lists the fuses by circuit, and the fusible link (LINK,FUSIBLE) is shown separately in the Wiring Diagram section on page 131. Work out which circuit failed first, then trace it on the wiring diagram to pull the correct part number.
Where do I find the key switch part number for a no-start, unresponsive-ignition condition on the L355SS?
The Hour Meter and Switch section on page 123 itemizes the SWITCH,STARTER (key switch) with its part number, which is the part to check for an ignition that does nothing when turned. The Panel section on page 121 lists related switch and connector parts, so glance at it before ordering, and confirm serial-range compatibility in the parts index.
What format is this Kubota L355SS manual in?
