KIOTI DK4520
Attachments that fit.

The standard DK4520 pairs 44.9 gross engine hp with 38.9 PTO hp and an 8F/8R synchronized-shuttle transmission. A chipper can clear its minimum power while still missing its full-feed condition, and a hydraulic mower needs optional rear-valve hardware verified.

Scope of this guideSynchronized shuttle · 8F/8R · 4 WD · ROPS. Each configuration below states the model and equipment covered by its sources.

Choose around the exact PTO rating and installed rear hydraulics.

  • 38.9 PTO hp clears WC88’s 35 minimum but does not meet WC68’s over 40 full 6-inch/full-feed condition.
  • The 62.8-inch minimum-tread tractor width makes the difference between 55- and 70-inch cutting swaths worth measuring on the actual tire setup.
  • The main-pump specification is 9.62 gpm in the U.S. manual; 14.56 gpm is its main-plus-steering total, not established flow at the rear ports.

Choose the exact configuration.

Where the documents disagree.

Hydraulic flow

Current page labels pump capacity 14.70 gpm/55.10 L/min; current brochure gives 14.6 gpm/55.1 L/min. The U.S. manual gives 14.56 total, explicitly split 9.62 main and 4.94 steering.

Preserve the documented manual circuit split and the page discrepancy. None is a verified rear-coupler delivery rate.

FIELD GUIDE

PTO wood chippers for the KIOTI DK4520

The standard DK4520 has 38.9 PTO hp, enough for WC68’s operating band and WC88’s minimum, but below both chippers’ full-diameter/full-feed conditions. Its 44.9 engine hp also sits just inside WCAP5’s explicitly engine-based 45 hp ceiling, creating a separate lighter gravity-feed option to evaluate.

Flail mowers for the KIOTI DK4520

For the DK4520, the useful WoodMaxx comparison is the actual 55- versus 70-inch cutting swath, not the 62H/78H model number. Both hammer configurations include 38.9 PTO hp in their published ranges, but the wider machine adds weight and both need rear hydraulic connections that are optional on this standard tractor.
