Is this a math problem?
"How long will it take B2620 traveling at 6mph and an L3800 going 8 mph, each headed to the other from 6.5 miles apart, to meet?"
When I had my Kubotas, I had a brother who lived about a mile and a half from us as the crow flies but because of an arm of the lake in the way, it was about 8 miles by road and I drove the kubotas there and back quite a few times. My wife had a brother who lived about 4 miles from us and I drove the kubotas there and back a few times. But when I was working with a neighbor cutting and baling hay, I drove his Oliver to hayfields as far as 15 miles each way.
I drove my old Kubota, and the current NH to help out at our fire station. It is about three miles. The B8200 was B29710/2910/7800 sized, but only 19hp. It was a long drive with only 19hp... The 40hp NH does it easy.
In the 1950's my Grandfather got a Ford tractor; my Dad drove it home about 35 miles. Brand new, drove from the dealer to home/ranch.
I wouldn't call it scenic, but I had mine for 6 days when I drove it 6 miles to church to respread a couple loads of gravel. Took 45 minutes. Or 250 yards to help the neighbor pick rocks so they could sod after building the house.
I've driven past them, and also been passed by them. They did not seem to be concerned. But, I had headlights on, and blinkers on. And, the SMV plate on the back of the tractor.
