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 LS Tractor MT240E or TYM T574C, pick an attachment type and model, and read Pass/Fail/Partial on hitch, PTO, and lift.

LS Tractor MT240E vs TYM T574C

Both sit in the Compact class with similar engine horsepower (40 vs 55 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 T574C lists higher engine horsepower (55 vs 40 HP). That is not a PTO advantage — confirm shaft power separately before buying cutters or tillers.
TYM T574C is heavier (4,233 vs 2,881 lb operating weight) — usually more stability and traction; LS Tractor MT240E stays easier to maneuver in tight yards.
TYM T574C has more rear lift (3,050.6 vs 1,808 lb @ 24″) — more headroom for heavier three-point tools. LS Tractor MT240E needs lighter implements or stricter ballast discipline.
Both list Category I — hitch class alone does not settle the matchup; lift and PTO still decide implement fit.
TYM T574C has the higher verified PTO rating (44.7 vs 34 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 LS Tractor MT240E when you need lower operating weight (2,881 vs 4,233 lb) for tight yards.

Choose TYM T574C when you need more rear lift (3,050.6 vs 1,808 lb @ 24″) for heavier three-point tools, higher verified PTO (44.7 vs 34 PTO HP) for cutters, tillers, or snow blowers, or more frame mass (4,233 vs 2,881 lb) for traction and stability.
