Which is better — Solis S75 or Solis S90?

Solis S90 lists higher engine horsepower (90 vs 75 HP). That is not a PTO advantage — confirm shaft power separately before buying cutters or tillers. Solis S90 is heavier (7,297 vs 7,231 lb operating weight) — usually more stability and traction; Solis S75 stays easier to maneuver in tight yards. Choose Solis S75 when you need lower operating weight (7,231 vs 7,297 lb) for tight yards. Choose Solis S90 when you need more frame mass (7,297 vs 7,231 lb) for traction and stability. 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 Solis S75 or Solis S90, pick an attachment type and model, and read Pass/Fail/Partial on hitch, PTO, and lift.

How to choose

Solis S90 lists higher engine horsepower (90 vs 75 HP). That is not a PTO advantage — confirm shaft power separately before buying cutters or tillers.
Solis S90 is heavier (7,297 vs 7,231 lb operating weight) — usually more stability and traction; Solis S75 stays easier to maneuver in tight yards.
Verified PTO horsepower is missing on both — look it up on the OEM sheet before you buy. We never invent shaft ratings.
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 Solis S75 when you need lower operating weight (7,231 vs 7,297 lb) for tight yards.

Choose Solis S90 when you need more frame mass (7,297 vs 7,231 lb) for traction and stability.
