maxwell99 12-02-2012 19:07:34 208.137.161.83 Report to Moderator	I have a 6ft Altas 300, 3 pt disc, it has 18" blades and all notched blades, front and rear gangs. Nice disc and cuts good, but it leaves a deep ditch on the outside of each rear gang. i have tried pulling a drag, but the outside rear notch blades catch on the drag and sometimes, bind up the rear gangs, would it be possible to cut the rear gang, outside blades down some, say 3 inches, this would cut the notches out of the blades back to a smooth blade, this might stop the rear blades from catching my drag and also leave smaller outside furrows. another thing I have seen is sometype extention you weld or bolt onto the outside blade that has an smaller disc blade and this blade fills in the ditch of the regular outside blade, do not know if this trick would stop the notch blades from catching the drag. any ideas would be helpful before next years garden plowing starts. this year i just did not use my drag, but it left the gardens rougher. Thanks. picture of a disc like mine [Reply]   [No Email]

The rear gangs need to be moved outward somewhat. They also need to be set one or two positions less aggressively than the front gangs. Rear gangs are running in soil that has already been loosened by front gangs, so that soil is easier to move. Hence, rear gang doesn't need to be as aggressive to move same amount of dirt. Don't shorten top link much, or you'll lose the effects of the rear gangs. Disc needs to run LEVEL front to rear for the most part, with SLIGHT adjustments as needed to fine tune. I've got an 8-1/2' Massey Ferguson #25 disc that does an incredibly fine job of working and leveling a seed bed. I use it when building waterways and filter strips. I use a slightly worn down disc blade on the outside of the rear gangs. That takes care of the "dead furrow" effect. As mentioned, move rear gangs outward somewhat. That will lessen the center ridging where rear gangs throw too much dirt in a pile if rear gangs are cutting. I prefer rear gangs to be about one disc spacing wider than front gangs. Also, play with ground speed to tune results. A well adjusted disc often doesn't need a drag behind it to leave a level, well worked seed bed. [Reply]  [No Email]

When I looked at the picture of the disk I thought too that the rear gangs were pushed together too much. I have a 5' three-point disk that is similar to the one shown and it does a nice, even job when the third link is properly adjusted. Without a "furrow filler" (these are usually smaller and have three lobes) blade on the rear gangs it is impossible not to leave small furrows on the edges but the key point is to have the rears moving the same amount of soil back in as the fronts move out. If this is not happening the little furrows will be only a minor annoyance compared to leaving the whole swath uneven. [Reply]  [No Email]

As previously stated leveling the disk,installing a furrow filler attachment or removing outside rear disk and installing smaller disk on the very outside rear. [Reply]  [No Email]

However, I don't know if they will bolt to your particular disk or not. [Reply]  [No Email]

Shortn the top link, so the weight is more evenly distributed, the disk front gang throws the dirt out, the rear gang pulls it back in, shorten the top link to get a better balance. --->Paul [Reply]  [No Email]
