“Fits” = within the manufacturer’s rated PTO HP range. “At limit” = below the minimum by 5–15%, will feel underpowered on seasoned hardwood. “Too small” = undersized for reliable chipping. “Oversized” = above range (works but overkill).

Buyer fit

Who should buy the BX36S — and who should skip it

Buy the BX36S if...
  • You own a tractor with 12–30 PTO HP and a Category 1 three-point hitch.
  • Your typical branches are 2–3.5 inches in diameter.
  • You chip mostly straight material and want the simpler, more reliable self-feeding mechanism (fewer hydraulic components to service).
  • You plan to keep the chipper 5+ years and value the 5-year warranty.
  • You want a capable chipper under $3k without stepping up to commercial-grade pricing.
Skip it if...
  • You don't own a tractor. A gas-standalone chipper of comparable capacity is the right category for you.
  • Your branches regularly exceed 3.5 inches. Step up to a 5.5-inch-capacity chipper — forcing this unit at the limit bogs the feed and accelerates blade wear.
FAQ07 questions

BX36S — frequently asked questions

01
How much tractor HP do I need for the BX36S?
The Wallenstein BX36S 3.5-inch PTO Woodchipper is rated for 12–30 PTO HP. That's tractor PTO horsepower after drivetrain losses — rated engine HP is typically 10–15% higher. A 14 HP engine tractor produces roughly 12 PTO HP and would run this chipper at the minimum. The comfortable working range is 15–27 PTO HP.
02
Does the BX36S fit a Category 1 three-point hitch?
Yes. The BX36S mounts to a standard Category 1 three-point hitch and accepts a 540 RPM rear PTO shaft (included). Quick hitch compatibility varies by brand — most John Deere iMatch and Pat's Easy Change hitches accept it with a standard top-link bushing.
03
What's the maximum branch diameter the BX36S can chip?
The Wallenstein BX36S 3.5-inch PTO Woodchipper is rated for branches up to 3.5 inches in diameter. Green and softwood branches chip reliably at the rated maximum. Seasoned hardwood at the maximum slows the feed rate and bogs the flywheel more — plan for 2.5-inch hardwood as your comfortable working size.
04
What's the warranty on the BX36S?
Wallenstein covers the BX36S with a 5-year warranty. It covers manufacturing defects but excludes wearing parts (blades, belts, bearings under normal wear) and cosmetic damage.
05
Is the BX36S self-feeding?
Yes — the BX36S uses a gravity + mechanical self-feeding design. Infeed rollers are driven by the flywheel. Works well on clean straight branches; forked or crooked material can hang up on the rollers and need to be manually nudged through.
06
How much does the BX36S weigh?
The Wallenstein BX36S 3.5-inch PTO Woodchipper weighs approximately 395 lb. Check your tractor's three-point hitch lift capacity before purchase — a Category 1 tractor typically lifts 1,200–1,800 lb at the hitch pins; Category 2 lifts 2,500+ lb.
07
How often do the blades on the BX36S need sharpening?
For typical property use (20–40 hours per year), sharpen the BX36S's blades once per season. Heavy hardwood use cuts that to every 15–20 hours. A full replacement set runs roughly $80–$250 depending on blade count and material. See our woodchipper blade sharpening guide for the full process.
