Massey Ferguson 1835E · PTO WOOD CHIPPERS
The 1835E HST’s 34.5 rated engine hp and 27.6 PTO hp fall on opposite sides of two different 30-hp ceilings. BX36S limits its published engine range to 30, while WC46 limits its PTO range to 30. Using 27.6 for both would incorrectly keep the smaller Wallenstein in the same numeric shortlist.

BEST MATCHES FOR THE 1835E
13 of 19 pto wood chippers we track pass the published power, hitch and speed screen. “Specs line up” cards come first.

THE DECISION IN NUMBERS
Use the exact power basis printed by each manufacturer. The tractor brochures do not verify a gross/net engine test standard. No row approves geometry, load or full-diameter work, and an unstated maximum is not unlimited-power approval.
Scroll the table sideways on smaller screens.
| Chipper | Published power basis | Correct 1835E HST check | Feed / load evidence |
|---|---|---|---|
| BX36S | 12–30 engine hp | 34.5 is 4.5 above maximum | Gravity feed; 395 lb Total Weight, operating inclusion unresolved |
| BX52S | 22–55 engine hp | 34.5 is inside engine band | Gravity feed; 505 lb Total Weight, operating inclusion unresolved |
| WC46 | 15–30 PTO hp | 27.6 is inside PTO band | Onboard hydraulic feed; 587 lb product |
| MX-9900 | 25 PTO hp minimum; finite maximum unstated | 27.6 is 2.6 above minimum | Onboard hydrostatic feed; 816 lb approximate dry, not operating |
BX36S’s current U.S. page explicitly says Engine HP Range. The 1835E’s 34.5 rated-engine figure exceeds its 30-hp upper value even though 27.6 PTO hp would appear to fit. WC46 explicitly uses PTO power, so 27.6 belongs in its 15–30 check. BX52S’s 22–55 engine band offers a different gravity-feed range, but its larger label is still only one condition. Ask the maker to confirm the applicable engine-rating basis before approving any pairing.
BX52S uses gravity/manual feeding. WC46 provides hydraulic infeed, while MX-9900 uses its own operator-controlled hydrostatic feed system. The two powered-feed chippers do not need tractor rear remotes for those documented arrangements, and no automatic load sensing or automatic reverse is established for MX-9900. Compare the control the work requires rather than treating the 1835E’s implement-pump output as a measure of chipper feeding performance.
Wallenstein does not publish a model-specific minimum-power/full-diameter guarantee in the reviewed BX-S sources. WC46’s over 20 PTO-hp full-four-inch/full-feed condition is numerically exceeded by 27.6, but that is not a test of this tractor and material. MX-9900’s 25-hp minimum is separate from its nine-inch marketing and 50+ HP full-capacity statement, whose power basis needs confirmation. Branch shape, species and feed conditions still require a model-specific answer.
The 1835E brochure’s PTO reference is 540 rpm and its HST drive is labeled transmission-driven. BX-S documentation supports 540 or 1,000 rpm as discrete settings, which does not mean this tractor has a 1,000-rpm PTO or that every supplied shaft suits both. Confirm the 540 setup, exact controls and stationary-use instructions. Then reconcile complete operating masses and centers of gravity against the tractor’s 1,598 lb at 24-inch reference, rather than comparing 505 lb total, 587 lb product and 816 lb dry as interchangeable loads.
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 Massey Ferguson 1835E’s 34.5 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, 1,598 lb, carries the 845-lb BX52RI with 753 lb to spare. Wallenstein lists no price; ask a dealer.
THE SCREEN, WITH ITS LIMITS VISIBLE

Is the WC46’s adjustable hydraulic feed and folding chute worth considering over the BX36S fixed gravity hopper?
