I would brush hog it and disk it. I use a Ford 3 cylinder diesel.
Have a 6ft brush hog and a 24" tandem disk I bought in 1969.
The only thing I have had to do to the tractor Is a new starter and 2
front tires in 36yrs. Of course I have changed the oil's in all the case's
many times. Still has the 2 original lug tires in the rear.
