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 John Deere 1R-25 or TYM T254, pick an attachment type and model, and read Pass/Fail/Partial on hitch, PTO, and lift.

How to choose

TYM T254 lists higher engine horsepower (23.9 vs 23 HP). That is not a PTO advantage — confirm shaft power separately before buying cutters or tillers.
The gap vs John Deere 1R-25 is small (~0.9 HP) — rear lift or hitch class often matter more day to day.
John Deere 1R-25 is heavier (1,872 vs 1,638 lb operating weight) — usually more stability and traction; TYM T254 stays easier to maneuver in tight yards.
TYM T254 has more rear lift (1,101 vs 915 lb @ 24″) — more headroom for heavier three-point tools. John Deere 1R-25 needs lighter implements or stricter ballast discipline.
Both list Limited Category I — hitch class alone does not settle the matchup; lift and PTO still decide implement fit.
TYM T254 has the higher verified PTO rating (18.8 vs 18.2 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 John Deere 1R-25 when you need more frame mass (1,872 vs 1,638 lb) for traction and stability.

Choose TYM T254 when you need more rear lift (1,101 vs 915 lb @ 24″) for heavier three-point tools, higher verified PTO (18.8 vs 18.2 PTO HP) for cutters, tillers, or snow blowers, or lower operating weight (1,638 vs 1,872 lb) for tight yards.
