I found a web site in canada that evaluated round balers. Here is what it said about a 241. It says the HP req was 25 hp. My 300 could run that. Summary of International Harvester 241 Bigroll Baler Overall Performance: Overall functional performance of the International Harvester 241 round baler was good. Ease of operation was fair while ease of adjustment was good. Operation of the twine wrapping mechanism was good. Capacity: Average field speeds varied from 6 to 16 km/h (3.8 to 10.0 mph) while average throughputs varied from 1.7 to 7.5 t/h (1.9 to 8.3 ton/h). Maximum instantaneous feedrates up to 18 t/h (19.8 ton/h) were measured in heavy, uniform hay windrows. Ground speed was usually limited by pickup loss and not by baler capacity. Feeding was aggressive in most crops. In short wheat and barley straw, feeding was hesitant causing occasional plugging in front of the compression rollers. Bale Quality: Bales were well formed and neat. The International Harvester 241 produced bales with an average length of 1.5 m (59 in) and an average diameter of 1.9 m (75 in). Hay bales weighed from 590 to 731 kg (1300 to 1610 lb) with an average density of 140 kg/m³ (8.7 lb/ft³). Resistance of bales to moisture penetration was good. Peak power take-off requirements were about 19 kW (25 hp) in hay and straw on flat firm fields. More power was needed on soft or hilly fields. Leaf Loss: Leaf loss was comparable to that of other large round balers. In heavy conditioned windrows at optimum moisture content, bale chamber loss was 2% while pickup loss was 1%. In light, dry unconditioned hay an average bale chamber loss as high as 15% and pickup loss of 16% can be expected. Heavy windrows, proper conditioning and baling at the maximum permissible moisture content all were important in reducing bale chamber loss. Operator Safety: The International Harvester 241 was safe to operate if the manufacturer's safety recommendations were closely followed.
