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 Kioti CS2230H or Kubota BX2680, pick an attachment type and model, and read Pass/Fail/Partial on hitch, PTO, and lift.

Kioti CS2230H vs Kubota BX2680

Both sit in the Sub-Compact class with similar engine horsepower (21 vs 24.8 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.

How to choose

Kubota BX2680 lists higher engine horsepower (24.8 vs 21 HP). That is not a PTO advantage — confirm shaft power separately before buying cutters or tillers.
Kioti CS2230H is heavier (1,735 vs 1,521 lb operating weight) — usually more stability and traction; Kubota BX2680 stays easier to maneuver in tight yards.
Hitch differs: Kioti CS2230H (Category I) vs Kubota BX2680 (Limited Category I). Implement sheets must name the matching class — adapters do not add lift.
Kubota BX2680 has the higher verified PTO rating (19.5 vs 16.7 PTO HP) — that is the Fact for cutters, tillers, and snow blowers, not engine HP.
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 Kioti CS2230H when you need more frame mass (1,735 vs 1,521 lb) for traction and stability, or implement sheets that explicitly list Category I.

Choose Kubota BX2680 when you need higher verified PTO (19.5 vs 16.7 PTO HP) for cutters, tillers, or snow blowers, lower operating weight (1,521 vs 1,735 lb) for tight yards, or implement sheets that explicitly list Limited Category I.
