i know that diesel engines are low revving compared with petrol but it seems that the petrol engines on old tractors like the te20 max revs are 1700 which seems really low for a 2.0 wheras a 2 litre engine these days would max out at about 6500 is there something in the design?
why dont petrol tractors rev high

Just the way the engine is designed . A longer stroke for the piston will produce more torque . Older gas tractor engines usually had very heavy flywheels and it takes torque to turn all that weight . The reason for the heavy flywheel is once its turning it takes a lot to stop it .
A shorter stroke engine will produce their power by rpms .

Yep long stroke = torque. We have a 1950 AR Deere and rebuilt the 2 cylinder gasoline engine about 6 years ago. Bore on it 5.50" stroke 6.75" compression 5.6:1 with the power rated at 975rpm. The old gal will pop along all day working and never a hint of backing down!!

It has so much torque though I hardly need to go that high unless
I'm commuting from 1 side of the block to the other I tend to stay in 3rd
Most of the time it's got that much torque
