Kubota Diagnostic Software – Diagmaster for Kubota Engines

Kubota Diagmaster is the software behind Kubota's Denso common-rail diesels and the equipment they power. Here's what shops ask us:

Will it fit my engine?

Yes for Kubota common-rail diesels — the V1505, V2203, D1105 and the 07/V3 families used in tractors, mini excavators, skid steers, mowers and gensets, plus repowered units in other brands' machines.

Can it force a DPF regen?

Yes — Diagmaster runs manual/stationary DPF regeneration (including the deeper Level 4 & 5 routines) for a machine stuck derated in a regen loop.

What else does it handle?

  • Read/clear DTCs and view live data
  • Actuator (output) tests
  • Injector compensation / injection-quantity correction after an injector swap
  • Supply-pump learning
  • Programming blank ECUs

What adapter?

A Denso DST-i interface. We install and license everything remotely and stay on to help with your first regen.

Send the engine model number and we'll confirm before you buy.
