Hazard
In the power transmission system, the fastening bolt of the connecting component (primary shift rod) linking the primary shift lever and the travel HST (hydrostatic continuously variable transmission) was improperly tightened, resulting in insufficient fastening torque in some units. Continued operation may cause the primary shift rod connecting component to detach, and in the worst case, the vehicle may not stop even when the primary shift lever is placed in the neutral position unless the ignition key is turned to OFF.

動力伝達装置において、主変速レバーと走行用ＨＳＴ（静油圧式無段変速機）をつなぐ連結部品（主変速ロッド）の固定ボルトの締め付け作業が不適切なため、締付トルクが不足しているものがある。そのため、そのまま使用を続けると主変速ロッド連結部品が外れ、最悪の場合、主変速レバーを中立位置にしても、イグニッションキーを“ＯＦＦ”にしなければ、車両が停止しないおそれがある。
Remedy
Inspect the bolt fastening condition on all vehicles. If fastening is inadequate, replace the bolt and retighten it.
