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 CS2220 or Kubota BX1880, pick an attachment type and model, and read Pass/Fail/Partial on hitch, PTO, and lift.

Kioti CS2220 vs Kubota BX1880

Both sit in the Sub-Compact class with similar engine horsepower (21 vs 16.6 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.

How to choose

Kioti CS2220 lists higher engine horsepower (21 vs 16.6 HP). That is not a PTO advantage — confirm shaft power separately before buying cutters or tillers.
Kioti CS2220 is heavier (1,554 vs 1,336 lb operating weight) — usually more stability and traction; Kubota BX1880 stays easier to maneuver in tight yards.
Hitch differs: Kioti CS2220 (Category I) vs Kubota BX1880 (Limited Category I). Implement sheets must name the matching class — adapters do not add lift.
Kioti CS2220 has the higher verified PTO rating (16.3 vs 13.7 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 CS2220 when you need higher verified PTO (16.3 vs 13.7 PTO HP) for cutters, tillers, or snow blowers, more frame mass (1,554 vs 1,336 lb) for traction and stability, or implement sheets that explicitly list Category I.

Choose Kubota BX1880 when you need lower operating weight (1,336 vs 1,554 lb) for tight yards, or implement sheets that explicitly list Limited Category I.
