Kioti RX6620 vs Kioti RX7320
Both sit in the Utility class with similar engine horsepower (66 vs 73 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 RX7320 lists higher engine horsepower (73 vs 66 HP). That is not a PTO advantage — confirm shaft power separately before buying cutters or tillers.
- Kioti RX7320 is heavier (5,589 vs 5,202 lb operating weight) — usually more stability and traction; Kioti RX6620 stays easier to maneuver in tight yards.
- Kioti RX7320 has more rear lift (3,898 vs 3,594 lb @ 24″) — more headroom for heavier three-point tools. Kioti RX6620 needs lighter implements or stricter ballast discipline.
- Both list Category II — hitch class alone does not settle the matchup; lift and PTO still decide implement fit.
- Kioti RX7320 has the higher verified PTO rating (63 vs 57.6 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.
