I have an eight foot Perfecta, which has 15 S tines. It came with 
13x 4"Danish shovels plus two outside straight points. They are now 
pretty worn and I'm going to order new shovels for it. I love the 
machine but the 4" shovels don't cover the total width and leave some 
weeds behind. Also, although the soil looks very smooth behind the tool, 
there are ridges underneath the soil. I'm thinking of going with a 7" 
Danish shovel. So my question is: has anyone done something similar and 
what do they think of the results?  Would 7" shovels make it really hard 
for my 60 and 50 hp tractors to pull it? Would it tend to clog up a lot 
more?
     If you have thoughts on this, let me know and maybe we can have a 
phone conversation about it. (I hate texts and emails for having 
meaningful conversation, but they are a start.)
