Which is better — Kioti RX6620 or Solis S75?

Solis S75 lists higher engine horsepower (75 vs 66 HP). That is not a PTO advantage — confirm shaft power separately before buying cutters or tillers. Solis S75 is heavier (7,231 vs 5,202 lb operating weight) — usually more stability and traction; Kioti RX6620 stays easier to maneuver in tight yards. Choose Kioti RX6620 when you need lower operating weight (5,202 vs 7,231 lb) for tight yards. Choose Solis S75 when you need more rear lift (5,512 vs 3,594 lb @ 24″) for heavier three-point tools, or more frame mass (7,231 vs 5,202 lb) for traction and stability. Use the Fit checker for your heaviest attachment instead of comparing engine HP alone.

Are these numbers invented?
