The Wheel Horse D-250 is a true SGT.
Engine- Renault 19.9hp 4 cylinder liquid cooled rated at 3000RPM
1,500RPM Front and Mid PTO- 1,000RPM Rear PTO
Trans, 4 forward 1 reverse with High/Low Range and Differential Lock

The is was only rated at 19.9HP for some rule used in tractor ratings, in other uses the same engine is rated a just over 30HP.
I would say the Superest of Super Garden Tractors
