Abstract
The present invention is a small transmission for riding lawn mowers and the like. The transmission includes a detent arrangement which aids the operator while shifting the transmission gears. The detent arrangement includes detent recesses which are formed in the casting of the housing, and a biased detent mechanism mounted on the shift fork of the transmission. The biased detent mechanism includes a projection on the shift fork which receives a spring and nose cone. The spring urges the nose into the detent recesses so that the shifting mechanism holds the transmission in the selected gear, and provides a positive feel of the changing gears. Alternatively, a spring biased ball may be mounted on the shift fork to engage the detent recesses.
