Abstract
A system for automatically preventing gear shift operation in a timber harvesting tractor when the tractor is moving. The system includes a drive train powered by a transmission. The drive train includes a transfer case which is shifted by the operator of the tractor through manipulation of an electrical control circuit. The electrical control circuit is rendered ineffective to shift the transfer case when the drive train is being driven by the transmission and the tractor is moving.
