The first 316 was the same basic machine as the 300 and it was only made for one year in 1978.
Capable of using many of the same attachments as the JD 140, the 300 series of John Deere garden tractors began production with the 1975 model year. In that year, the hydrostatic model 300 was introduced, replacing the John Deere 140 and its seven-year production run. Although it shared many components from the 140, the 300 was upgraded to a 16HP Kohler K-series engine and had numerous styling changes. Major changes included a more squared off hood with integral headlights, engine side panels and a black plastic instrument panel. Realizing the liability of mounting a metal gas tank under the hood next to the battery, the model 300 had a plastic gas tank relocated under the rear fender pan with an increased capacity of 4.5 gallons. The John Deere 300 came equipped standard with a two-spool hydraulic lift system, a departure from the single or three-spool system available on the model 140. The charge pump and differential were largely unchanged from the 140, with the charge pump being manufactured by Sundstrand and the differential assembly by Dana. Individual rear wheel brakes also came standard on the model 300. Notably absent on the left side of the tractor was the clutch disconnect/ neutral return pedal found on the model 140. Identical to the model 300, the model 316 (Kohler powered) was manufactured during 1978 only. This particular model is often confused with the later series model 316, which was produced from 1984-1992. Being distinctly different tractors, there are few similarities between the early and late versions of the model 316. Manufactured briefly from 1977 to 1978, the model 312 provided a basic, no frills 300 series tractor with 12 HP Kohler engine, no engine side panels, no ammeter, H1 hydraulics, narrower rear tires, and a single brake pedal for both rear wheels. Headlights were an option on the 312.
The later 316 was powered by the same Onan as the 318.
In 1984, the 318 was joined by its little brother the 316. Basically the same tractor as the 318, but without power steering and having only 1 spool of hydraulics. In 1986 the 330 joined the team, Deere’s first diesel powered Lawn and Garden tractor. And in 1988, the 330 was replaced by the 332, a diesel and the 322 was added with a 3 cylinder gasoline engine. The 330, 332, and 322 were all liquid cooled and the engines were sourced from Yanmar, the supplier of John Deere’s compact tractor line since 1979.
