3020--1963-1972

4020--1963-1972


The story is told that one of John Deere's early partners found him working on one of his early plows and chided him for time and effort being spent improving what was already the best and most widely sought plow on the market. "We must continue to improve our product," Deere reportedly answered, "or others will and we will lose our trade." In much the same spirit, the 3010 and 4010 were replaced just three years after their introduction. Reason: The engineers had developed something better. . .the 3020 and 4020, the latter destined to become the most popular tractor of its time.
 
The 3020 and 4020 were more powerful than the tractors they replaced. But the big news was Power Shift transmission. The operator could use a single lever to shift between any of eight forward gears or four reverse gears, under load, on the go, and withour clutching. Those forward speeds were practical, properly spaced, and ideal for any tractor job. Combined with the flexibility of variable-speed engines, this permitted pinpoint selection of power and speed. An "inching" pedal provided "clutch action" for maneuvering in tight quarters and backing to implements. The time-proved Synchro-Range trasmission was available as an option to Power Shift.
 
The 3020 and 4020 also introduced a hydraulic power differential lock which, when a foot pedal was depressed, directed power equally to both drive wheels for improved traction in mud, snow, or other difficult operating conditions.
 
The 3020 was originally rated at 65.28 PTO hp. See State of Nebraska Tests No. 848 (1963), No. 851 (1963), No. 940 (1966), No. 941 (1966), No. 1010 (1969) and No. 1011 (1969).
 
The 4020 Diesel was originally rated at 91.17 PTO hp. See State of Nebraska Tests No. 849, No. 850, No. 853 (1963); No. 930 (1965); No. 934, No. 939 (1966); No. 1012, and No. 1024 (1969).
