Now thats a piston

[skife]

What would you say this are for?

2 cycle?

Who cares, its a tractor.

All you talk about is tractors, I've got one but you dont see me bragging about it.

2 pistons = not the greatest amount of horsepower but gobs of torque to spare. God I don't miss living on a farm at all.

My dad's company makes pistons, from small ones for lawnmowers, to garbage-can size for cruise ships... the big display piston in their lobby is about 30" in diameter, 4' tall, and is constantly having bits of trash put in it by people who don't realize that the holes in the sides are for the 8" connecting rod pin...

Engines are cool, I shoulda been an engineer...

HAVE YOU SEEN THESE PISTONS??? THEY'RE GINORMOUS!!![/will ferrel]

lmao i love elf

Now I know absolutely nothing about tractors, but did you say a four cylinder engine starts the two cylinder diesel? Why would you have to have an engine to start an engine? I am not trying to prove anyone wrong or anything, but it just sounds funny. Usually an electric starter motor is used to start up most engines. I just don't know why an actual 4 cylinder would be used to get a 2 cylinder going.

Well it would take me to long to type it out so here:

"Beginning with the model R in 1949, Deere enginners had to figure a way of starting the big diesel engines. Hand starting; the very common way to start the tractor engines of the day, was NOT an option. While the R only had 416 cubic inches of displacement (in comparison, the kerosene fueled hand start D had 501 cubic inches), its compression ratio of 16:1 made hand starting with the flywheel impossible!

The electrical systems of the day could not handle the job either. 6 volt systems had no chance, and experiments with 24 volts failed as well.

So it was finally decided that a starting engine needed to be used. A starting engine is a small gasoline engine that is used to crank over the larger diesel engine. This concept had been proven successful with various earlier diesel engines, including some Caterpillar tractors."



The smaller one is used in the pony motor
THis video shows you how that works:

Hope that helps
