What the ministry says is wrong
刈取脱穀作業車の動力伝達装置において、設計検討が不適切なため、テンションアーム支点軸周辺の溶接の溶け込みが不足しているものがある。そのため、機械稼働による振動や衝撃により、溶接溶け込み不足部位に応力が集中し、最悪の場合、テンションアーム支点軸が破断し、走行不能となるおそれがある。What is to be done about it
以下対策を実施した部品へ全数交換する。 １テンションアーム支点軸径を大きくし、溶接を追加したもの。 ２テンションアームの板厚を大きくし、剛性を向上させたもの。 ３テンションスプリングを変更し、密着長に余裕をもたせたもの。 ４テンションロッド組み付け部に回動支点を追加したもの。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.

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 380 Japanese vehicle recall notifications filed in 2025.
