A nice looking John Deere model 620 that appeared at the 2018 Silverstein FireFest Car Show held in Independence Missouri.
In 1957, John Deere introduced the "20 Series" tractors, again with more horsepower and more yellow in its paint scheme. The "320" was the bottom on the line for small farmers and its horsepower was never tested. The "420" had 21 HP on the drawbar, the "520" had 26 HP, the "620" had 35 HP, the "720" had 51 HP, and the "820" reached a new record of 70 HP. Prices ranged from $1,885 for the "320" up to $4,850 for the "820" with standard equipment.
The John Deere Model 620 tractor was a direct replacement for the 60, but it offered close to the same horsepower of the Model 70 at practically the same price.
Even with it's advanced features and beautiful bright paint job, plus improved operator convenience, a new Model 620 was only about 100 dollars more than what a new Model 70 had cost.
The 620 was advertised as a full 4 plow tractor with the power to handle heavy loads continuously at speeds that would cut days off a farmer's work calendar.
It had a bore and stroke of 5 1/2 x 6 3/8 inches, 321 cid, 1125 rpm, 44.16 drawbar and 48.68 belt horsepower.
Major changes were made to the Model 60 engine including: shorter stroke, aluminum pistons, larger rod and main bearings, a stronger crankshaft, redesigned cylinder head, and higher compression.
Another addition which made the engines run a bit smoother was the distributor was now driven directly off the camshaft instead of previously being driven through the governor. This was also incorporated on the 520 and 720.
The oldeere (pun intended) two cylinder tractors had fired on the compression and exhaust stroke. With the new camshaft driven distributor they now only fired on the compression stroke, which allowed longer point and spark plug life.

Model 620 1956 to 1958
Variations of the John Deere Model 620 Tractor include:
620 general purpose
620 O
620 S
620 H
All models were available with either gasoline, all fuel or LP Gas engines. Front end options were dual narrow, dual Roll O Matic, wide front, or single wheel.
A major improvement on the 20 series of tractors was the hydraulic system with Load and Depth Control. This system actually sensed when more weight was needed on the rear wheels and if the load became too much, the system would automatically raise the implement enough to get it through a tough spot.
The Custom Powr Trol hydraulics had a stop which could be set by the operator so that a precise working depth would be maintained for each row once an implement was raised.
The new universal 3 point hitch on these tractors was a major
improvement over the old 800 and 800 A hitches. A new line of integral equipment was developed especially for these tractors.
A new foot pedal was incorporated on the 520, 620 and 720 which activated the PTO in place of the old style pull up lever.
A new dipstick was used on these tractors. With the old tractors a valve was opened and if the oil ran out you knew it was full, if it didn't a farmer would pour in oil until it ran out.
Tractors before serial number 6213100 have green dash panels and black generators. After that they had black dash panels and green generators.
Serial number 6200004, the 4th Model 620 built was used as a yard tractor at the Waterloo Tractor Works, it is still owned by John Deere, however has been retired from active duty.
The cost of a new 1958 Model 620 Tractor was $3,200
Shipping weight was 5858 pounds.
At Nebraska, the 620 set a new fuel economy record on the drawbar for gasoline tractors and was second to the 520 for economy on LP Gas.
The 620 O was the last two-cylinder orchard tractor. It continued to be manufactured until February 1960. Tractor Series #1
There were a total of 22,532 Model 620 tractors built of all variations. 427 of these were orchard, 48 hi crops, 988 standards and the rest row crops.
40 late production Model 620 tractors were shipped for assembly at Monterrey, Mexico in February of 1958. Serial number tags for these tractors had John Deere de Mexico stamped on them.
Szerencsém volt , hogy ottjártamkor kelepelt, nagyon erős hang..!.

There are six genera with nineteen living species of stork.
Storks tend to prefer warm, dry places and they are found in
most such regions of the world. Storks are mute because they
have no syrinx (the vocal organ of birds) so instead they
communicate through bill clattering when they are together
in the nest.
