The back blade I use on my wd has roughly 300 lbs of ballast. Well, it had 300lbs. One of the 50lbs weights fell off. We don't have a welder big enough to reattach it. Anyway, I was wondering, why would I need the ballast? Any other blade I have seem does not have this extra ballast. I am thinking of cutting the other 50lbs ballast off and just having 200 lbs on it. |

No blade needs that much ballast. The idea of using ballast is to allow the blade to actually drag soil as it moves. However, when the angle of the blade is set properly this ballast is not needed. The proper angle will allow the blade to drag soil as opposed to just riding on top of the ground.

Is this a snap coupler A-C blade? Personally, I have never even considered adding weight to mine and it is run on a D15II. Depending on soil conditions, you need to adjust the blade cutting depth/angle while restricting the speed. This assumes the corners are good along with the general cutting edge and I have done plenty of work including general grading of a very hard 700-800' gravel drive, adjusting/maintaining diversion ditches and specifically removing trees while clearing land. I use my SC blade (without the extensions) in the rearward position as I can "snap" cedar roots by hitting the trunk about 2' above ground, and I mean hit em with a good lick in reverse; I am not using the blade but the plate assembly. I have a single chain wrapped around the pipe frame and use two other chain lengths so I can make three "pulls" on up to 8" cedars that I have loosened by popping them backwards. Hook onto them near ground level and if loosened correctly, they come right out of the ground and off to the burn pile we go. I am always amazed at how well built the SC blades are and I have yet to require weld repair on the one of mine I use the most, and it has done plenty of work for being such a light blade. I do not feel I could get as rough with my 3-pt. A-C blade, vs. the SC blade. My favorite kind of "tractor therapy". |

My blade is not a snap coupler blade. It appears to be a 3pt blade that was fabricated to kind of work with the snap coupler. Thanks. Right now the blade has 150lbs on one side and 100lbs on the other (since the 50lb weight fell off). I may just cut the 50lbs off the other side to make it balanced again. It seems like I only use this to remove snow. I didn't see a reason for that much weight either. I doubt I need that much for doing a gravel driveway either!

In the winter I add two 65 pound suitcase weights to my back blade. It works very well when the driveway gets icy to scratch up the ice so it isn't so slippery to walk on. It also does not want to ride up on a wet sticky snow with the weight. I suppose if you could have constant down pressure it would not be needed. Al

| Still, two 65lb weights (130lb) is quite a bit less then the 300 I have now. |

I would add more if I had them, tried wheel weights and unless I do a major redo I have a hard time keeping them in place. Al

all I know is that every year my SC blade gets heavier for me to move by myself.... Jay must be getting old...... ------------- 3 D-14s,A-C forklift, B-112 Kubota BX23S lil' TOOT( The Other Orange Tractor) Never burn your bridges, unless you can walk on water |

| I hear that Jay; funny how a 8' 4x4 seems to be stored near where I park my blade starting a few years back. Sure makes it easier to nudge it sideways a tad so I can get my latches on . . . . |

great minds think alike !! gee Tim ,and I thought I was the only one with a 'helper' near the blade! I use a 7' section of 2" pipe.It's lighter than any 4by4 I got...mind you 'someone' tends to borrow my nice wood.
