Kubota MX6000 · PTO WOOD CHIPPERS
The MX6000 HST’s 51.8 PTO hp exceeds WC68’s 50-hp maximum, so more tractor power removes that option from the normal range. Compare WC88, BX72S and MX-9900 using their different power bases and capacity conditions. The tractor’s 63.4 gross engine hp does not satisfy a claim that asks for over 60 at the PTO.

THE DECISION IN NUMBERS
Tractor reference: U.S. 4WD HST ROPS, 51.8 PTO hp and 63.4 gross / 59.5 net engine hp. No maximum is invented where a maker publishes only a minimum or an open-ended label. Capacity, feed method, mounting and complete load remain separate decisions.
Scroll the table sideways on smaller screens.
| Chipper | Published requirement | MX6000 HST result | Capacity or fit question |
|---|---|---|---|
| WC68 | 20–50 PTO hp | 51.8 exceeds maximum by 1.8 hp | Its over-40 capacity condition does not override the 50-hp upper limit. |
| BX52S | 22–55 engine hp | 63.4 gross and 59.5 net are both above 55 | The engine-standard ambiguity cannot move either published tractor rating inside this band. |
| WC88 | 35 PTO hp minimum; full 8-inch/full-infeed condition over 60 PTO hp | 51.8 clears minimum but is 8.2 below 60 | Larger opening and powered feed do not establish full-diameter performance at full infeed speed. |
| BX72S | 50–85 engine hp; 7-inch diameter label | 63.4 gross and 59.5 net are numerically inside | Confirm material conditions, delivered Category 1/2 hardware and the intended 540-rpm configuration. |
| MX-9900 | 25 PTO hp minimum; separate 50+ HP full-capacity statement | 51.8 PTO clears minimum and the numerical 50 reference | Obtain the standard, material conditions and applicable maximum behind the separate 50+ claim. |
The WC68 page’s over-40-PTO-hp condition for full-diameter logs at full infeed speed exists inside its published 20–50 PTO-hp range. At 51.8, this tractor is above the upper end by 1.8 hp. Satisfying the capacity condition does not erase the maximum. BX52S is also outside its engine band: both Kubota’s 63.4 gross and 59.5 net ratings exceed 55. There is no supported reason to change ratings, feed settings or PTO speed to make either product appear inside its stated range.
WC88’s current page places its full-8-inch/full-infeed condition at over 60 PTO hp. The MX6000’s 51.8 PTO hp is below that condition even though the gross engine number begins with 63. Its 35-PTO-hp minimum is a different threshold, which the tractor exceeds. A buyer can discuss the larger opening and powered infeed without claiming that this pairing meets every full-capacity statement. Ask Woodland Mills for the supported conditions for the actual species, moisture and branch shape rather than translating engine power into PTO output.
MX-9900 states at least 25 PTO hp, then separately advertises full 9-inch material with 50+ HP without repeating the horsepower basis in that sentence. The MX6000’s PTO figure is already above 50 numerically, but the basis, material conditions and permitted upper power still need clarification. BX72S names a 50–85 engine-hp range and a 7-inch diameter rating. It uses gravity/manual feed, while MX-9900 and WC88 use self-contained powered infeed. None needs a tractor rear feed circuit. Opening dimensions and feed arrangements do not establish a measured processing rate.
Kubota’s flail-specific 1,100-lb limit cannot be borrowed as a chipper allowance; the reviewed tractor implement table has no chipper row. The manual still requires sold or approved implements. Have Kubota assess the exact chipper and its complete load center. WC88’s 900-lb product figure, BX72S’s 728-lb reference and MX-9900’s approximately 816-lb dry figure use different bases and do not establish shaft-and-fluid-inclusive operating mass. The tractor’s Category 1/2 capability also does not resolve BX72S’s page/manual category difference. Confirm delivered hardware and a tractor-specific shaft arrangement using the documented rear 540-rpm output.
Wallenstein’s current pages rate the 7-inch BX72RI (45–85 engine hp, Category I and II). 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 Kubota MX6000’s 63.4 engine hp is inside the BX72RI’s range on both the page and the manual. Its published lift at 24 inches, 2,310 lb, carries the 1,300-lb BX72RI with 1,010 lb to spare. Wallenstein lists no price; ask a dealer.
