I don't where you are going to find two 80/820/830 for under $12,000-$15,000 each. Then the time and money to hack them up into a tandem hitch . You are well into paying for a 4455M4WD by that point. The 4455 has diff lock, sound guard body , high flow hydrualics, 1000rpm pto, three point hitch and air conditioning. Add those to your 830 tandem hitch for less than the price of a 4455.
Care to guess that the price difference would be on a tandem 830 hitch at an auction vs a 4455M4WD at your retirement?
The M4WD was used as a comparison as it's driving on two axles like the jackleg tandem 830 hitch.
You were watching a strain gauge and mph indicator? Or watching the tractors from the side of the field? I'll take science over a seat of the pants dyno.
Where pray tell did 400cu" and 500HP come from ??? The 4455 has a 466 cu" engine making less than 150 net Hp.
The 450HP engine with 1200 cu" you like Is being pushed 119% harder than the 466 making 147pto Hp.

Although he himself has never actually owned or restored a tractor, he was always enthusiastic and always around helping with other peoples projects.
