A timing mark is an indicator used for setting the timing of the ignition system of an engine, typically found on the crankshaft pulley (as pictured) or the flywheel. [1] These have the largest radius rotating at crankshaft speed and therefore are the place where marks at one degree intervals will be farthest apart.
The John Deere Model R tractor was John Deere's first diesel tractor. A large, heavy tractor, it had fixed wheel widths and was not produced as a row-crop tractor with adjustable axles. The R was followed in the John Deere numbered model series by the John Deere 80, 820 and 830 tractors, which represented evolutionary upgrades to the basic R.
In a piston engine, either a timing belt (also called a cambelt) or timing chain or set of timing gears is a perishable component used to synchronize the rotation of the crankshaft and the camshaft. This synchronisation ensures that the engine's valves open and close at the correct times in relation to the position of the pistons.
This engine was the first to locate one balance shaft higher than the other, to counteract the second order rolling couple (i.e. about the crankshaft axis) due to the torque exerted by the inertia caused by increases and decreases in engine speed. [6] [7] In a flat-four engine, the forces are cancelled out by the pistons moving in opposite ...

In a spark ignition engine, a mixture is ignited by an electric spark from a spark plug — the timing of which is very precisely controlled. Almost all gasoline engines are of this type. Diesel engines timing is precisely controlled by the pressure pump and injector. The normal plug distance between the spark plug is 1mm apart, and the voltage ...
John Deere Model 60 (1955) John Deere Model 530 (1959) John Deere Model 430S (circa 1960) After years of testing, Deere & Company released its first proper diesel engined tractor in 1949, the Model R.

The H was introduced in 1939 as a much-scaled-down version of the John Deere Model G.It was a general-purpose row-crop tractor, intended for smaller farms. As with most row-crop tractors, the spacing between the rear wheels could be adjusted to suit row spacings.
