TYM T394 · PTO WOOD CHIPPERS
The mechanical ROPS T394 has 30.2 PTO hp in both the current exact-model brochure and the 2026 catalog. That is above WC46’s published 30-hp maximum, even though the difference is small. WC68, the current FH-BX62 manual range and MX-9900 offer different feed and load questions once the exact tractor configuration is confirmed.

BEST MATCHES FOR THE T394
11 of 19 pto wood chippers we track pass the published power, hitch and speed screen. Each still has a detail to confirm with the seller.
PTO chipperWoodland Mills
6″ max. chip diameter · 20–50 PTO hp
Confirm the conflicting tractor specifications in your serial-specific manual; official source values differ.
PTO chipperFarmer-Helper
6.5″ manual feed-opening short side, inches · 25–45 PTO hp in current index-linked manual; older capacity/range conflicts retained
Confirm the complete operating weight; a shipping weight cannot establish the attachment load.

THE DECISION IN NUMBERS
Power inclusion is a preliminary numeric result, not fit approval or full-capacity output. The cab T394C’s separate 30-hp entry and HST marketing are not substitutes for this mechanical ROPS rating. Unknown maximum means no finite maximum was verified, not unlimited approval.
Scroll the table sideways on smaller screens.
| Chipper | Published PTO requirement | Result at 30.2 PTO hp | Remaining capacity / load question |
|---|---|---|---|
| WC46 | 15–30 hp | 0.2 above published maximum | Do not round the tractor rating down |
| WC68 | 20–50 hp | Inside band | Below the over-40 condition for full 6 in/full feed; 747 lb product |
| FH-BX62S | Current index-linked manual: 25–45 hp | Inside selected band; source conflicts remain | Gravity feed; full-capacity statements conflict; operating mass unknown |
| MX-9900 | 25 hp minimum; finite maximum unstated | 5.2 above minimum | 816 lb approximate dry, not operating; 9-inch output not established |
TYM’s exact T394 column says Mechanical F12xR12 and 30.2 PTO hp; the adjacent T394C cab column says 30. The page also contains HST marketing. These are not interchangeable ratings. For the selected mechanical ROPS scope, 30.2 exceeds WC46’s 30-hp maximum. Do not round it down, substitute cab data or assume reducing throttle creates an approved pairing. The actual tractor and chipper manufacturers must resolve any proposed exception.
WC68 has controlled hydraulic feed with an onboard pump and reservoir. FH-BX62S uses gravity/pinch-and-pull feeding rather than a powered feed roller, while MX-9900 has its own operator-controlled hydrostatic feed system. None of these options depends on fitting the T394’s optional rear remotes to run the documented feed arrangement. That makes feeding control a purchase distinction, while PTO input, hitch geometry and rear load still require their own checks.
WC68’s maker requires over 40 PTO hp for full six-inch logs at full feed, above this tractor’s rating. The current FH-BX62 manual gives a 6.5 × 12-inch material opening, while page and older documents also use seven-inch marketing and conflicting full-capacity power claims. MX-9900 starts at 25 PTO hp but associates full nine-inch capacity with a separate 50+ HP statement whose basis needs confirmation. Minimum power, opening dimensions and full-capacity conditions are different evidence.
The current T394 lift figure at 24 inches is 1,558 lb. WC68’s 747 lb product label, FH-BX62S’s conflicting net/gross/shipping figures and MX-9900’s approximately 816 lb dry weight do not all describe the same assembled condition. Obtain the shaft-and-fluid operating mass and center of gravity for each candidate, then confirm the applicable TYM manual, front ballast, axle limits and allowed hitch travel. The higher 2,639 lb end-ball-joint figure does not close those questions.
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 TYM T394’s 37.4 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, 1,558 lb, carries the 845-lb BX52RI with 713 lb to spare. Wallenstein lists no price; ask a dealer.
