The damage to the tractor would come from the transmission output shaft being spun way too fast. The bearings are splash lubricated on the old non pressurized tractors and the heavy transmission lube can't get carried up the gears and run into the bearings fast enough. If the output shaft is run at engine speed when in high gear it is spinning from 1000 to maybe 2000 RPM's at the fastest and the tractor is going 12-15 MPH. Bump the speed up to 25 or 30 MPH and that transmission shaft is turning possibly 2500-5000 RPM's depending on the tractor. At that kind of speed the oil gets slung off the gears before some of it can dribble into the bearings. Some tractors can take it, some can't. I was pulling an SC Case down the road with a hitch at 25 MPH back in my younger days. The transmission was in neutral. All of a sudden BANG the transmission shifted itself into two gears at once and the rear wheels were sliding. After I stopped I messed around with the shifter and got it back into neutral and away I went again only at 10 MPH like I should have been in the first place. I am still driving that tractor today and have never had the transmission apart.
