Based on my research, this has not been attempted before, but the problems are severe, pervasive, vexing, and costly. I am looking to assemble a group of owners who have had repeated issues with their DPF systems, repairs, and long stays at the dealer, and who can provide data in addition to anecdotes (patterns of repair, costs, contacts with Kubota, etc.). The first step is to assemble such a group and then take the process outside this forum to create a strong, well-documented legal case.

Has anyone tried a manual injection pump or modifying the pump to manual??
The B3350 engine is mechanically injected.

The injection pump is not the problem. The reformer based emissions system is the problem.

As both a former B3350 owner and attorney, I doubt that you will find attorney(s) willing to fund such action as the class will be far too small.

Trying to get a class action lawsuit going on a 16 year old model of tractor is a huge up hill battle.

Spend the lawyer money on a delete kit instead.

Agreed.

Rather easy to do on 3350 as engine is mechanically injected.

I believe that a company in Turkey (probably others as well) sells a module that fakes out the tractor electronics to keep the indicators and beepers off. Don't know anything about the reputation of the company.

I should also mention that Kubota has issued a "Lifetime Warranty" for the emissions system of the B3350. This warranty is transferrable to subsequent owners and covers the reformer and other components damaged by a failed reformer, e.g., DPF. Kubota has not publicized this policy and your dealer may be unaware or may not tell you even if he is aware. I hava a PDF copy and can send a copy by email if you desire. I've never taken the time to learn how to post such things here.

FWIW, the 2018 B3350 that I once owned demonstrated emissions problems immediately after delivery and was back to the dealer several times (once for nearly 3 months) for updates, etc. Finally Kubota bit the bullet and replaced the reformer, DPF, etc., and it performed properly afterward. Dealer told me that bill for that visit would have been $7-9K had it not been covered by warranty, and that was pre-Biden.

Yes, one must follow the emissions system operation instructions in the Owners Manual precisely, e.g., do not shut down when the engine is performing a regen, etc., but I had no more issues after the last dealer visit, nor has the subsequent owner.

I bundled the B3350 with my farm when I sold it in preparation for a 1,700+ mile relocation to avoid trying to sell the B3350 myself.
