Orange part numbers are Amazon affiliate links (we may earn a commission at no cost to you). Specs, intervals and procedures come from Kubota’s manual; the problem patterns are owner-reported and are not Kubota-published causes.

Our source is the L3560/L4060/L4760/L5060/L5460/L6060 Operator’s Manual, code TD350-1958-2 (2014), the cab supplement TD350-7956-2 and Kubota’s 2020 Grand L60 brochure. Earlier versions of this page used a 200-hour oil interval and listed no capacities for the transmission or front axle; the manual gives the figures above.

• Regen indicator flashing, then staying on during regeneration
• “Raise rpm” indicator on the IntelliPanel
• Buzzer that gets faster as the warning level rises
• Reduced engine output at the higher levels

Parked regeneration (p. 26) needs: parking brake applied, HST pedal neutral (or GST/manual shuttle neutral), PTO off, engine idling, DPF-INHIBIT lamp off, implement lowered and front wheels straight. These are DPF protections, not coolant-overheat thresholds. Oil matters too: the manual specifies DPF-compatible CJ-4 oil. See our DPF regen failure guide and engine oil cross reference. Earlier versions of this page said to use the inhibit switch only in a burn ban; the manual describes the inhibit lamp but we did not find that restriction, so follow the manual’s procedure.

• Abrupt speed changes from small pedal movements (an owner-reported pattern)
• Weak drive under load
• Whine or hesitation

The HST Plus has three ranges with Hydro Dual Speed (brochure). Check the fluid level and condition first. The manual calls for the HST filter every 200 hours (HST only), the hydraulic filter and fluid every 400 hours, and Super UDT-2 (regular UDT permitted). Fresh fluid and filters are the cheap first step before blaming the transmission; if drive is still weak, have a dealer test it. See our HST transmission problems guide and HST jerking guide.

• Engine will not crank, with a message on the IntelliPanel
• “Disengage PTO” or “Set HST Pedal to Neutral” (HST)
• “Set Shuttle to Neutral” (GST/manual)
• Intermittent no-start (owner-reported)

• HST: PTO off, speed-control pedal in neutral (foot removed)
• GST/manual: PTO off and shuttle in neutral; fully depress the clutch pedal
• Parking brake set, fuel cock open

If the messages are correct but the tractor still will not start, work from the battery and grounds outward: clean and tighten terminals and ground straps, then inspect the safety switches. See our safety switch guide, ground strap guide and battery guide. Earlier versions named a Group 24 battery at 575–582 CCA and a battery-disconnect cause; we could not source either, so we removed them.

• Loader lifts slowly at low rpm (owner-reported, often below about 1,600 rpm)
• 3-point raises slowly under a heavy implement
• Improves at working rpm

• Test at working rpm before assuming a fault
• Hydraulic fluid level and condition (shared with the transmission, 42 L)
• Hydraulic filter (every 400 hours) and any air after a filter change
• Pump pressure and relief setting by a dealer if it is still weak at working rpm

See our loader won’t lift guide and 3-point hitch guide. Earlier versions quoted pump flow in gpm and dealer repair costs; we could not source them.

We found no reason for the difference, so both are shown. These are ROPS and cab weights without a loader or backhoe. A tractor this heavy at 37 gross HP will feel less lively in heavy ground work than a lighter machine. Before blaming the engine, rule out the cheap causes: a restricted air filter, a DPF at warning level 3 or 4 (50% output), and low fluid. Earlier versions quoted different weights and a 13.5 gal fuel tank; we have not re-verified the tank figure.

The manual lists DPF muffler cleaning every 3,000 hours (pp. 109–110). Kubota requires a specific cleaning device and directs dealer service rather than owner disassembly. Scheduled ash cleaning and ordinary regeneration are separate: the 3,000-hour interval is not a regeneration interval. Earlier versions listed EGR cleaning intervals, 2-year sensor-hose replacement and DPF cleaning and replacement prices; we could not source them, so they are not repeated here. See our DPF cleaning guide.

The first-service (break-in) assignment could not be read from the schedule, so we do not state one. Messick’s dealer chart prints the transmission oil as “11.1 qts”; the manual prints 42 L (11.1 US gal), so we follow the manual.

Many Amazon kits advertise TA040-93230 and the older TA040-93220 together; those are aftermarket, not Kubota approvals, and we have not linked them. We found no complete serial split, so confirm by serial at Kubota’s parts lookup or on our parts diagrams page. Earlier versions listed glow plug 19077-65510 and a Group 24 battery; neither was verified, so they are not shown.

• The reason the 2014 manual and 2020 brochure weights differ.
• Whether a DEF system exists (we made no claim either way), and the fuel tank capacity.
• The first-service job assignment, and any belt or filter serial split.
• Owner-reported patterns (surging and stalling, loader feel at low rpm, abrupt HST response), costs, EGR intervals and sensor-hose intervals from earlier versions, which we removed.
• Whether any recall applies: we found no L3560 notice at Kubota USA’s safety-notices page on Oct 24, 2026. That is a search result, not a full history.
