THE DECISION IN NUMBERS
Tractor reference: Kubota M5-111, January 2026 catalog; Category II; 4,630 lb at 24 in. (8-speed).
Scroll the table sideways on smaller screens.
| Chipper | Published requirement | On 89 PTO / 105.6 engine hp | Result |
|---|---|---|---|
| Wallenstein BX102S | 80–120 engine hp; Category II | Inside at 105.6 (14.4 under the maximum) | Fits |
| WoodMaxx MX-9900 / MX-8800 / WM-8M / WM-8H | 19–25 PTO hp minimum; 50+ for full capacity; no maximum; Category 1/2 | Inside; 39 over the 50+ line | Fits |
| Wallenstein BX102RI | 75–120 engine hp (page); hydraulic feed; 10-in. | BX102RI inside | Fits on page and manual; hydraulic remote or power pack |
| Wallenstein BX72S | 50–85 engine hp; Category I and II | 20.6 over (PTO 4 over) | Excluded |
| Woodland Mills WC88 | 35 PTO hp minimum; Category 1 | Power inside; hitch mismatch | Excluded |
| All other chippers here | To 55 hp or less | Over | Excluded |
Both are WoodMaxx hydrostatic-feed chippers listing Category 1/2: MX-8800 (8-inch) from 20 PTO hp and MX-9900 (9-inch) from 25. The M5-111 clears both and their 50+ full-capacity line. The comparison below sets them side by side.
Wallenstein’s 10-inch BX102S runs 80–120 engine hp on a Category II hitch only, gravity-fed, at 1,143 lb. The M5-111’s 105.6 gross hp sits inside it; this is the one chipper here with a published ceiling above the M5-111. Confirm the pins, the PTO shaft for 540 or 1,000 rpm, and front ballast for its weight.
WoodMaxx publishes no maximum, so this site does not exclude the M5-111. Its 89 PTO hp is 78 percent more than the 50 WoodMaxx names; ask which shear bolt or slip clutch the PTO shaft carries and whether it is rated for this tractor.
Wallenstein rates BX72S at 50–85 engine hp. The M5-111’s 105.6 gross hp is 20.6 over, and even its 89 PTO hp is 4 over, so BX72S is screened out on either figure.
Kubota lists a Category II hitch with telescopic lower link ends. Category 1-only attachments such as Woodland Mills WC88 and Land Pride FM2560 would need bushings or a quick hitch approved in writing; this site screens them out.
Wallenstein’s current pages rate the 10-inch BX102RI (75–120 engine hp, Category II). Two hydraulic rollers pull material in at a set rate, and P3 PULSE reverses them when the rotor slows; they need 4–8 gpm from a rear remote or Wallenstein’s PTO-driven power pack. The Kubota M5-111’s 105.6 engine hp is inside the BX102RI’s range on both the page and the manual. Its published lift at 24 inches, 4,630 lb, carries the 1,950-lb BX102RI with 2,680 lb to spare. Wallenstein lists no price; ask a dealer.
