Kubota Tractor Service
Kubota diesel tractors work every day—tilling, mowing, baling, loading, and pulling. We keep them productive with test-first diagnostics, OE-spec parts/fluids, and documentation your operation can trust.
Diagnostics & common repairs
- Aftertreatment & emissions: frequent regens, DPF/DOC/SCR service, EGR coolers/valves, NOx/DPF differential pressure/EGT sensors, dosing and wiring faults.
- Fuel & power: hard starts/derates, air-in-fuel, water contamination, rail-pressure control (Denso SCV), injector balance/return, HP pump testing.
- Air & cooling: turbo and charge-air leaks, radiator/CAC cleaning, viscous/fan-drive faults, overheating under load.
- Driveline & chassis: 4WD front-axle seals/kingpins, hub bearings, steering play, brake service, vibration under tow.
- Hydraulics & PTO: slow loader/remotes, hitch drift, draft control, remote valve leakage, PTO clutch packs and speed sensors.
- Electrical/CANBUS: intermittent no-crank/no-start, ECU/ CCM ground issues, ISOBUS connector power, harness rub-through and connector pin fit.
- Cab & HVAC: heater/AC performance, blower speeds, charge and leak checks.
Models & engines we see often
- L/MX Series: L2501–L6060, MX4800–MX6000 (V1505/V2403/V3307).
- M Series: M5/M6 (V3800/V6108), M7-1/M7-2/M7-3 (KVT/Powershift with V6108), specialty/orchard variants.
- Articulated & heavy utility: M6-XX, M7-XX with loaders and hay gear.
- Engines: Kubota V1505, V2403, V3307, V3800, V5009, V6108—plus support for Cummins B6.7 on M8 where applicable.
Major repairs — engine
- Compression/leak-down, injector return, rail-pressure and boost testing to confirm failure before parts.
- EGR cooler/valve, turbo service, intake/charge-air system reseal.
- Injector and high-pressure pump replacement with contamination flush and tank/system cleaning.
- Head gasket, timing/front cover/oil leaks, cooling-stack refresh.
- In-chassis overhauls on V-series where economical; post-repair calibrations and loaded road/dyno validation.
Major repairs — transmission & driveline
- HST, GST (Glide Shift), Intelli-Shift powershift, KVT (CVT): pressure testing, clutch/pack wear checks, range/ratio sensor diagnostics, controller adaptives.
- Repairs and reseals, valve-body/solenoid service, cooler flow and thermal checks.
- Front-axle & final drive reseal/rebearings; brake discs and park systems.
- R&R with programming/adaptation and field validation under load.
Hydraulics & PTO
- Pump flow/pressure testing, priority/compensation checks, SCVs and power-beyond repairs.
- 3-pt hitch position/draft calibration, lift-cylinder reseal.
- PTO speed signal, clutch pack pressure, and brake drag corrections.
Preventive maintenance & seasonal setup
- Interval-based oil/fuel/air filtration, water-separator service, coolant test/exchange (OAT), axle and transmission fluids to spec.
- DPF maintenance by hours/back-pressure, regen verification, and sensor health.
- Valve-lash checks on applicable V-series.
- Pre-season inspections: hydraulics/SCV flow for hay gear, hitch & PTO validation, tire/ballast and drawbar/weighting for heavy draft.
- Records that simplify audits and resale.
Field service & uptime support
- Mobile service for no-starts or down equipment, after-hours harvest support when possible, and parts sourcing matched to serial and spec.
- Clear estimates, failure photos, and close-out reports you can hand to owners or accountants.

Kubota Tractor Service FAQs
Quick answers to common questions about Kubota agricultural diesel service at Britt’s Diesel—models we cover, major engine & transmission repairs, in-season support, and severe-duty PM for heavy pulling.
M, MX, Grand L, M7, and RTV diesel lines—4-cyl V2403/V3307/V3800 and 6-cyl V6108 platforms, plus Tier 3–Tier 4 Final/Stage V variants.
Yes. We test sensors, dosing, differential pressure, EGTs, and wiring first; then perform forced regens, ash/soot load resets, and DPF cleaning or replacement only when data confirms it.
Absolutely—EGR/turbo/VGT service, injector and high-pressure pump with contamination flush, head gasket work, and short-block/long-block overhauls. For transmissions (HST, powershift, shuttle): clutch packs, valve bodies, solenoids, reseals, and calibrations.
We offer priority in-season scheduling, field calls when appropriate, and “ready-to-run” inspections that catch failures before they sideline a machine.
For Kubota M-/L-/MX-series working long, high-load days, stick to the manual and tighten intervals. Focus on heat, airflow, fuel quality, and driveline:
Daily (or every fueling): Blow out radiator/CAC/screens; check coolant level; inspect belts/hoses; drain water separator; grease loader/3-pt/PTO spline; walk-around for leaks & loose hardware.
Every 10–50 hours (dusty/heavy tow): Clean/replace air pre-cleaner & primary filter as needed (never over-oil); torque wheel lugs; check tire PSI/ballast for draft loads; grease U-joints & front-axle pivots.
250 hours or 6 months (shorten under extreme load): Engine oil & filter (Kubota-spec oil); final-drive & front-axle oil check; inspect brake linings and clutch/pedal free play (if equipped).
400–600 hours: HST/UDT/UDT2 transmission-hydraulic fluid and filters; service front-axle hubs; align toe-in if you see outer-lug wear from heavy draft.
500 hours or annually: Fuel filters (both stages); coolant test/top SCA as spec’d; battery load test & clean grounds.
800–1,000 hours: Valve lash check; complete driveline inspection (PTO, 3-pt ends, drawbar pin/bushings).
Aftertreatment care (Tier 4): Monitor soot load/DPF; ensure regens complete; fix intake/exhaust leaks; use clean ULSD + winter additive when needed.
Storage between seasons: Wash & blow fins, fog electrical connectors, fill tank, top off fluids, and park with implements lowered.
These steps reduce heat stress, keep torque up under draft, and extend engine, axle, and hydraulic life during heavy pulling.
