John Deere 4066R vs TYM T574C
Both sit in the Compact class with similar engine horsepower (65 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
- John Deere 4066R lists higher engine horsepower (65 vs 55 HP). That is not a PTO advantage — confirm shaft power separately before buying cutters or tillers.
- TYM T574C is heavier (4,233 vs 3,770 lb operating weight) — usually more stability and traction; John Deere 4066R stays easier to maneuver in tight yards.
- TYM T574C has more rear lift (3,050.6 vs 2,500 lb @ 24″) — more headroom for heavier three-point tools. John Deere 4066R 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.
- John Deere 4066R has the higher verified PTO rating (52 vs 44.7 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.
