Anything older than a Golden Harvester model (forget the model number; but it was the replacement for the 8N)...you don't want.
First came the redesigns by engineers who'd never used a tractor. The 1970s three-cylinder Fords were high-revving, low-torque POSs that made every task a chore.
Then came essentially, engineering-abandonment. Ford coasted for years on inertia, before selling out to New Holland.
Which I've not heard much good about. No one I've ever known, used NH equipment - I knew farmers who swore by Case; some Farmall fans; we ran Fords and a David Brown (defunct 1975) on the golf course I worked on, along with a couple specialty Jacobsen tractors. But New Holland...that was the company that the conglomerate Sperry bought up, and later sold off when Burroughs bought them, to focus on computer products.
Another money-grab...buy the industry, and then HARVEST profits, and then sell the tangibles and intellectual property once there's nothing left to bleed.
Glad you saved money. What the John Deere people are dealing with, now, with requiring Factory Service personnel deep in their fields, waiting weeks...it's well you did the job, no matter how hard.
