What the ministry says is wrong

農耕トラクタの前後進制御用電磁バルブ（シャトルバルブ）において、以下①②の内容により、検出スイッチの誤作動でエラーが発報し、フェールセーフ機能により走行停止することがある。また、そのまま使用を続けると走行停止後に走行不能に至るおそれがある。①シャトルバルブ内部の構造が不適切なため、バルブ内部に発生した極微小な油圧の圧力差によりスイッチ作動部部品が押されることで、検出スイッチが誤作動する。②設計検討が不十なため、検出スイッチが油浸されることで、検出スイッチ内部の接点に有機物が発生し、導通不良を引き起こすことで検出スイッチが誤作動する。

What is to be done about it

①全車両について、シャトルバルブの検出スイッチ作動部の部品を対策部品に交換する。②全車両について、対策プログラムに書き換える。

The two passages above are quoted in Japanese because that is the language the ministry published them in. This site keeps the wording a register had when it was read, and does not translate a safety notice.

Source: Ministry of Land, Infrastructure, Transport and Tourism website （出典：国土交通省ウェブサイト）, used under the Public Data License 1.0. This site gathered the record, grouped it by notification number and set it in English around the ministry's own words; the notice itself is unaltered. CarsMultiverse is not the ministry and not a safety authority. To act on this notice, use the ministry's own document.

The Japanese register on this site

クボタ elsewhere in this register

クボタ is named on 92 notices in the copy of MLIT’s register held here, of which these are the nearest to this one in time.

The same part: その他(動力伝達)

190 notices in this register name その他(動力伝達). A defect that keeps returning under one heading is worth reading as a group rather than one notice at a time.

Reading this against the source

This page is what MLIT published in the recall notices it publishes, kept as it was read. The authority publishes only its current wording; if a notice is rewritten, the earlier version disappears there and is kept here. The whole register is at /japan, and how the reading is done is set out in the method.

This register keeps an index of its own for every maker and every year it holds: Japanese recalls on a Kubota: 94 in the register, and 201 Japanese vehicle recall notifications filed in 2026.
