Jersey Jim - 12/6/2018 17:09 I have a 3 shank anhydrous bar with coulters, mole knives on chisel plow shanks, and disc sealers putting 180-200 lb actual N on 60 inch centers @ 5 mph for side dress application. This is in long term notil mostly level to some hills. The knives will run about where the mounting bolts are most of the time but the depth does not seem to matter. I have some trouble getting the anhydrous sealed with the current setup. Would any of the high speed units seal better? If so, which ones would you recommend? Thanks, Jim
Hmmm, I'm surprised you are having issues like that. I rarely have smoke come out, and that is mainly where I have wheel tracks/traffic. Are you seeing this where the combine/sprayer has driven?
Also, 200# actual is a lot. I am putting on close to 125# @ 5-7mph. Perhaps slowing down slightly will reduce the pressure enough to keep from blowing the gas out of the trench and give the soil time to absorb it?
I still think keeping the knives in a non-trafficked row is your best bet. That is how I have mine set up with controlled traffic.
