Jonathan, I don't know where you can get any of the "Big 3" for $17,000 with the extras Century has except that, HERE, I'm not getting a Century for that either. If the dealer from Oregon is willing to knock about $3500 off I could, but he would have to throw in a set of 17.5-24 R4's and 16.5 R4's, about a $500 option. I don't think he's going to do it. If you could tell me where I can get a Century with HST, that would be the real trick. Kubotas grille guard actually is standard with the loader, draft control is optional and a never used on my International, just don't utilize it. If I was considering another shuttle shift transmission, I would consider Century. I know nothing about them, their engines, transmission, front axle and steering, etc, all those things that are quite important for me.
The weight issue you mention is one I would issue a word of caution about. Manufactuers have no standard when it comes to tractors, tractor weights are even more evidence of this. Dry weight or wet, tires or no tires, many things that are often a source of confusion since the tractor is not shipped very often with tires. If 500lbs more weight was all it took to match or exceed the competition difference, one could so very easily add it. I take the manufactuers weight with a grain of salt. I understand the importance of weight, but simply having more is not necessarly all that is needed. My International weighs 6500lbs, R1's ballasted, 179 cu in diesel, 2WD and yet has no more obvious pulling ability then my L3830 HST as demonstrated by pulling my boxscraper with the rippers down, and thats with the Kubota in 2WD and with R4's unbalasted! Go figure, about 2500bs in weight advantage yet no obvious pulling ability advantage. Throw the Kubota in 4WD and there is no comparison. Granted the International would be the better choice for pulling something all day long that required lots of pull because of it's bigger size, engine and transmission, but a blanket statement that weight translates into more productivity is in my opinion, simply wrong. Rat...
Water
ballast is free and a quick way to add over 1000lbs, out here we don't even need antifreeze. I choose not to have it because my traction now is so good, I would rather keep the extra weight off for mowing purposes.
