did you get oil-lite bushings or straight bronze ? Oil-lite is what you want . As for the blade , from what I can see , the whole thing is tilted too much to the front . Looks to me like it needs to come back so it just about touches the cylinders . right now it looks like your corners are doing all the work and the middle is gliding along . Another thing to remember the coal blade will carry more volume to weight in coal then soil . Meaning , soil is much heavier then coal .
looks great , speed looks good . More inspiration to get my TD40 goin
