Going through the Kubota website, I really liked the specs on the
B3350 - BUT - read many reports on DPF regen issues. Reports I've read were as new as late 2017. Has anyone here purchased a new (2018)
B3350? Any knowledge on if the software updates Kubota has sent out have actually fixed the issue on prior year models?
I bought a new
B3350 about 8 weeks ago.
Among other things, I'm a long time design engineer and mechanic. Before buying, I researched thoroughly.
The
B3350 and associated F series professional front mount mowers using the same engine are the only Kubota farm/homeowner machines that use mechanical injection rather than the more modern common rail systems while also adhering to the nonsensical federale TIER IV regulations.
Accordingly, the regeneration algorithm is completely different for the
B3350 engine than for other larger Kubota common rail injected engines.
Yes, Kubota stubbed their toe badly with the
B3350 and associated machines, indeed, uncharacteristically so.
That said, it appears that most (all?) of the regeneration issues associated with the
B3350 and related machines have been resolved.
That also said, being an old design engineer, I would be very surprised if Kubota was not now redesigning the small 4 cylinder direct injected diesel engine with common rail (more costly) technology.
Also, being an old MBA/marketing type of guy, it would not surprise me if Kubota simply decides to abandon this small market segment in order to save the development costs for the sake of such nonsensical TIER IV nonsense.
Stay tuned.
