Re: *gear reduction unit
The big grippers I'm running are a bit taller than the stock tams of 83mm and I use the 12 tooth plastic pinion, that comes with wdc motors, on the output shaft from the twin motor coupler into the tam trans... the final drive output is somewheres around 50 rpm at the drive axle... and you're talking having ten times that with your wdc? That seems pretty quick for a heavy haul tractor.
The white tractor in my vids is usually running around in 2nd. I rarely ever use 1st. And flip into 3rd running empty, which is a bit faster than walking.
