KIOTI DK4520 · PTO WOOD CHIPPERS
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.

THE DECISION IN NUMBERS
DK4520 is 44.9 gross engine hp/38.9 PTO hp. In-range power does not confirm carrying limits, driveline fit or maximum feed performance.
Scroll the table sideways on smaller screens.
| Chipper | Published requirement | DK4520 comparison | Retained product weight |
|---|---|---|---|
| WCAP5 | 15–45 engine hp | 44.9 inside; only 0.1 hp below stated maximum | 412 lb |
| WCAP5 PRO | 15–45 PTO hp | 38.9 inside; source discrepancies remain | 386 lb |
| WC68 | 20–50 PTO hp; over 40 for full 6 in/full feed | 38.9 inside range; full-feed condition not met | 747 lb |
| WC88 | 35 PTO hp minimum; over 60 for full 8 in/full feed | Minimum met; full-feed condition not met | 900 lb; complete operating inclusions unverified |
WCAP5 uses an explicitly engine-based 15–45 hp range. Compare it with 44.9 gross engine hp, not 38.9 PTO hp, and keep the stated upper limit rather than rounding the tractor to a different value. WCAP5 PRO instead states a 15–45 PTO-hp range but retains conflicting manual language; the similar names do not make their power bases interchangeable.
WC68 and WC88 power their infeed from onboard hydraulic systems. The standard DK4520’s optional rear-valve status therefore does not decide this chipper comparison. The useful tradeoff is controlled feed and throat size against the complete implement load, with the 38.9 PTO-hp rating below the respective over 40/over 60 full-feed conditions.
WCAP5’s retained 412 lb product weight and WC68’s 747 lb are meaningfully different starting points for a load discussion. The DK4520 has a 2,716 lb lift rating 24 in behind the hitch and 2,998 lb at the lower link balls. Neither permits subtracting product weight to declare a safe transport allowance: attachment load center, front ballast, geometry and the tractor’s implement limits still govern.
Wallenstein’s current pages rate the 5-inch BX52RI (30–55 engine hp, Category I). Two hydraulic rollers pull material in at a set rate, and P3 PULSE reverses them when the rotor slows; they need 3–6 gpm from a rear remote or Wallenstein’s PTO-driven power pack. The KIOTI DK4520’s 44.9 engine hp is inside the BX52RI’s range on both the page and the manual. Its published lift at 24 inches, 2,716 lb, carries the 845-lb BX52RI with 1,871 lb to spare. Wallenstein lists no price; ask a dealer.
