Hi Hugh, Now mabey you neighbour just didn't have his Kverneland set up right.... I never knew George Burris, but the name is certainly famailiar to me. He was quite widely known. As for me, I'm down in Cape Breton, in the middle of Boularderie. I'm 28 since you asked... The major compliment of our soils here are of the Shulie series, with some Springhill. We also have a small amount of heavier ground. I forget the soil series. It may be Falmouth. If you're not familiar with Shulie soils, then lets just say you don't often plow with more than a 16" bottom, because you can't. There just isn't enough soil there above the shale/slate or bedrock in some places. Auto reset isn't an option here, it's standard equipment. When going is good, I like to plow at 5.5-5.75 mph. It's not uncommon to see sparks flying off the boards at night. If I'm in a particulairly rocky field, then I'm down to 4 -5 mph. Seriously though, I do believe that your neighbour's plow wasn't set quite right, unless you're dealing with a lot heavier soil than I'm accostomed to. I generally pull the 4AB with my Ford 7710, turned to about 105 PTO hp. It's variable between 12 and 20 inches, and I like to run it at about 17". She could take it faster, but I just don't push that hard. I also plow with a NewHolland TS90 which is rated at 70 PTO, although it probably makes a bit more. This tractor will maintain 4 mph under most contitions, and if things are good, it will hit about 5.5 mph. If the gearign was right, it would probably hold 5... but the gearing is wrong for the torque it's got. Again, this is at about 17" width, and 8" depth. By that standard, 120 hp on 5 seems like a lot. A neighbour is pulling 6x12"-22" with a 7710, again turned well over 100 hp. I can't say for sure just how much of that 22" he's actually pulling... but in certain contitions he probably can take most or all of it. He's got a 3650 Massey that's cranked close to 170 PTO, and he still plows with the Ford. One thing about our soil is that it is generally light. Also, as you say, everyone has their preference, and different reasons and conditions to go with it. I also think there's probably a fair difference in the bottoms that I'm using today and perhaps the Kverneland bottom of days gone by that you neighbour may have had. One of the major reasons we went with this plow was that the wear parts, on a per acre basis were a good deal cheaper than the old plows we were using previously, and the performance was not even comparable. That's just my experience with it. Rod
