Kubota B2301 vs Kubota BX23S (Sub-Compact)
Both sit in the Sub-Compact class with similar engine horsepower (20.9 vs 21.6 HP). Below: catalog Facts for engine horsepower, weight, and rear lift; PTO and hitch only when verified. The decision points call out who leads on each Fact — engine HP is not a substitute for PTO HP.
Engine horsepower is not PTO horsepower. Missing Facts show as — — we never invent shaft ratings.
Spec comparison

How to choose
- Kubota BX23S lists higher engine horsepower (21.6 vs 20.9 HP). That is not a PTO advantage — confirm shaft power separately before buying cutters or tillers.
- The gap vs Kubota B2301 is small (~0.7 HP) — rear lift or hitch class often matter more day to day.
- Kubota B2301 has more rear lift (1,411 vs 680 lb @ 24″) — more headroom for heavier three-point tools. Kubota BX23S needs lighter implements or stricter ballast discipline.
- Hitch differs: Kubota B2301 (Category I) vs Kubota BX23S (Limited Category I). Implement sheets must name the matching class — adapters do not add lift.
- Verified PTO horsepower is essentially even (17.4 PTO HP) — heavy PTO tools then hinge on lift and frame mass.
- Next step: open the Fit checker with the tractor that wins on your heaviest implement, and screen hitch, PTO, and lift against that attachment.
When to pick each
Choose Kubota B2301 when you need more rear lift (1,411 vs 680 lb @ 24″) for heavier three-point tools, or implement sheets that explicitly list Category I.
Choose Kubota BX23S when you need implement sheets that explicitly list Limited Category I.

FAQ
- Which is better — Kubota B2301 or Kubota BX23S?
- Kubota BX23S lists higher engine horsepower (21.6 vs 20.9 HP). That is not a PTO advantage — confirm shaft power separately before buying cutters or tillers. The gap vs Kubota B2301 is small (~0.7 HP) — rear lift or hitch class often matter more day to day. Choose Kubota B2301 when you need more rear lift (1,411 vs 680 lb @ 24″) for heavier three-point tools, or implement sheets that explicitly list Category I. Choose Kubota BX23S when you need implement sheets that explicitly list Limited Category I. Use the Fit checker for your heaviest attachment instead of comparing engine HP alone.
- Are these numbers invented?
- No. Engine HP, weight, and rear lift come from catalog Facts; PTO/hitch only from verified overlays. Missing Facts show as — — we never invent shaft ratings.
- How do I check attachments?
- Open the Fit checker with Kubota B2301 or Kubota BX23S, pick an attachment type and model, and read Pass/Fail/Partial on hitch, PTO, and lift.
