Kubota LX3520 · PTO WOOD CHIPPERS
The LX3520HSD’s 28.7 PTO hp clears MX-9900’s 25 hp operating minimum but not WC88’s 35 hp minimum, despite the MX model’s larger listed maximum chip diameter. This is a useful reminder that nominal diameter does not determine the tractor requirement across different chipper designs.

THE DECISION IN NUMBERS
Standard-width HSD ROPS only. Clearing a minimum does not promise the listed maximum diameter or full feed speed. MX operating weight remains unknown.
Scroll the table sideways on smaller screens.
| Chipper | Published PTO requirement | Result at 28.7 PTO hp | Retained load basis |
|---|---|---|---|
| WC46 | 15–30 hp; over 20 for full 4 in/full feed | Inside; 1.3 hp below maximum | 587 lb product weight |
| WC68 | 20–50 hp; over 40 for full 6 in/full feed | Inside; full-feed power condition not met | 747 lb product weight |
| MX-9900 | 25 hp minimum; no finite maximum stated | 3.7 hp above minimum; full 9 in output not established | 816 lb approximate dry; operating weight unknown |
| WC88 | 35 hp minimum | 6.3 hp below minimum | 900 lb product; operating inclusions unverified |
MX-9900’s listed maximum is nine inches, but its operating minimum is 25 PTO hp. WC88’s listed maximum is eight inches and its minimum is 35 PTO hp. The LX3520HSD clears only the former minimum. Neither comparison predicts what diameter, species or feed setting is appropriate at 28.7 PTO hp; those operating expectations still need manufacturer guidance.
WoodMaxx associates full nine-inch capacity with a 50+ HP statement whose power basis is not repeated in that phrase. The LX3520HSD has 34.9 engine hp and 28.7 PTO hp, both below 50. Resolve the exact condition and expected material before assuming the minimum-power result means maximum-size use. A finite upper tractor-power limit was not found; that omission is not unlimited-power approval.
Kubota’s detailed documents give 1,962 lb at 24 in behind lift point and 2,535 lb at the lift point. The web-model field labels the latter as 24-inch capacity. MX-9900 also has only an approximate dry weight of 816 lb and a separate 1,048 lb shipping figure. Correct both measurement bases before any carrying assessment; subtracting dry weight from either tractor figure does not approve the load.
WC46 and WC68 both include 28.7 in their power ranges, but only WC46’s stated full-diameter/full-feed power condition is met. Their retained product weights differ by 160 lb. Both use onboard feed hydraulics, as does MX-9900, so the tractor’s unresolved rear-remote equipment does not decide feed operation. Compare the actual branch task, complete load and approved setup.
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 Kubota LX3520’s 34.9 engine hp is inside the BX52RI page’s 30–55 but under the 40 that the manual’s table gives for the BX52R, so ask Wallenstein which floor applies to the serial on offer. Its published lift at 24 inches, 1,962 lb, carries the 845-lb BX52RI with 1,117 lb to spare. Wallenstein lists no price; ask a dealer.
