Only in thailand you can see a farm tractor like this with kubota engine race with a Mitsubishi diesel pickup truck!
Com: Buggy 65 : for those of us in north america ,this is called a hand tractor but I have no idea how you get a kubota flywheel engine to wind up like that and stay in one piece.
Com: Farmall tractor : An engine carrying a few pieces of steel and a guy beats engine carrying a truck and a guy; not really anything to write home about...
More importantly that dude riding the tractor has serious balls...
Com: Fuk Hea : The flywheel on the engine is storing lots of power.
As he revs the engine The flywheel stores several kilowatts of energy giving him a great launch off of the line.
Like a Hybrid Car with a battery pack and electric assist motor adding torque to the gas / diesel motor.
Once the flywheel energy is expended, it is up to the engine to propel the vehicle.
Remove the heavy flywheel and the tractor will loose it's ability to rapidly accelerate.
This is the most unusual drag vehicle I have ever seen and I love it!
Com: Miles dugmore : So what if you increased the weight of the flywheel
you are in fact storing more and more horse power as you rev up before the start....
so when you let the clutch out you can have a large amount of power stored in the flywheel.
