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 1E-23 or TYM T254, pick an attachment type and model, and read Pass/Fail/Partial on hitch, PTO, and lift.

John Deere 1E-23 vs TYM T254

Both sit in the Sub-Compact class with similar engine horsepower (21.5 vs 23.9 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

TYM T254 lists higher engine horsepower (23.9 vs 21.5 HP). That is not a PTO advantage — confirm shaft power separately before buying cutters or tillers.
The gap vs John Deere 1E-23 is small (~2.4 HP) — rear lift or hitch class often matter more day to day.
TYM T254 is heavier (1,638 vs 1,475 lb operating weight) — usually more stability and traction; John Deere 1E-23 stays easier to maneuver in tight yards.
TYM T254 has more rear lift (1,101 vs 758 lb @ 24″) — more headroom for heavier three-point tools. John Deere 1E-23 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 16.2 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 1E-23 when you need lower operating weight (1,475 vs 1,638 lb) for tight yards.

Choose TYM T254 when you need more rear lift (1,101 vs 758 lb @ 24″) for heavier three-point tools, higher verified PTO (18.8 vs 16.2 PTO HP) for cutters, tillers, or snow blowers, or more frame mass (1,638 vs 1,475 lb) for traction and stability.
