Last night I looked up specs and Nebraska Tests to compare W-30 to other W models. In physical size The W-30 is closest to the W-6. W-6 shipping weight on rubber 4990#, 247.7 cu in engine. W-30 shipping weight on steel 4820# (rubber would be more), 283.7 cu in engine. In power I used distillate models of the 4, 6, and 9, because that is the only way the 30 and 40 were tested. In belt horse power it is cloest to the W-6. W-6 34.23 belt hp vs F-30 32.80 belt hp. In pounds pull it is closest to the W-6. W-6 4755 lbs ant 1.96 mph. F-30 4157 lbs at 2.24 mph (F-30 was on steel. Would be higher on rubber). In drawbar horsepower it is closer to W-4. W-4 21.38 db hp. F-30 24.85 db hp (F-30 was tested on steel, would be higher on rubber). For Nebraska Tests I had to use the F-30 test as I could not find the W-30 test. I used the distillate tests for all tractors to be on equal basis. The W-4, 6, and 9 were on rubber and the W 30 and 40 were on steel. Test# 342 W-4 distillate on rubber, 152.1 cu in, weight as tested 5690#, 23.11 belt hp, 21.38 db hp, max pull 3297# @ 2.21 mph. Test# 354 W-6 distillate on rubber, 247.7 cu in, weight as tested 7744#, 34.23 belt hp, 31.40 db hp, max pull 4755# @ 1.96 mph. Test# 371 W-9 distillate on rubber, 334.5 cu in, weight as tested 10,190#, 46.36 belt hp, 42.67 db hp, max pull 6577# @ 2.02 mph. Test# 198 F-30 distillate on steel, 283.7 cu in, weight as tested 5990#, 32.80 belt hp, 24.85 dbhp, max pull 4157# @ 2.24 mph. Test# 269 W-40 distillate on steel, 298.3 cu in 6 cyl, weight as tested 7625#, 49.76 belt hp, 35.22 db hp, max pull 4982# @ 2.62 mph. (Note, db hp and max lbs pull would be higher on 30 and 40 if they had been tested on rubber tires to equal out results).Harold H
