Confirm the conflicting tractor specifications in your serial-specific manual; official source values differ.
KIOTI · COMPACT TRACTOR ATTACHMENTS
The KIOTI DK4220SEH is the smallest DK20SE: an HST tractor rated 39.6 gross engine hp and 29.1 PTO hp. That PTO figure is 0.9 under the 30-hp ceilings of Woodland Mills WC46 and TFG55 and 0.9 short of WoodMaxx FM-78’s 30-hp minimum, so it sits on the line between small and mid-size attachments. KIOTI’s brochure, web page and manual agree on the figures.
