Competition Turbine and multi engine tractor pullin rigs

[DBoyd]

I was watching the Bowling Green tractor pulls last night and got to wonderin how the power is transmitted to the rear diff from the turbine and multi engine tractors. Don't the turbine rigs have to run a gear reduction box to reduce the rpm from the turbines down to the final drive rpms?? and how are 4 turbines hooked into one final drive shaft? Also, what kind of power transmission apparatus is required for the multi engine rigs to have engines plugged in sideways and also straight in? And this is all in one rig!! That thing would have to be a driveshaft nightmare!!

Thanks for the help.

TTT... keeping this one on the front burner.



I've been to tractor pulls and wondered the same thing. I pity the poor son-of-a-gun that lets me take a look at his multi-engine tractor...



1) He/she won't be able to get rid of me for at least a few hours

2) There will be drool all over the place...

They are called cross boxes. Look closely.

The Turbines are about the same. . when multi they will use the cross box... The turbine basically has a fan blade that the air is pushing on. . there is no actual direct connection to the turbine wheel... They have a gear reduction on the output of the turbine. . then a gearbox... the Diff. . and then the outboard's. . There is no actual clutch. . they use a disk brake on the output shaft of the turbine. . you push on this to stop the speed of the output to change gears. . or hold it to get the turbine spooling up... A friend has built a few...

Should act no different than a Helicopter running both engines at flt idle and the rotor head locked with the brake, turn the break loose and select FLY on the throttles for 100% turbine speed.

good question



great pictures J. R. ...



TDR never ceases to amaze me ... my freinds are still oogling the pics of those broken tractor blocks from a few weeks back
