I prefer to suck in a pull string with a shop vac.  Then use that to pull in 
mule tape.

Tie an old bread sack or plastic baggie on pull string.  The vac will suck it a 
long way.

Yeah the blowing machine is expensive, but the company selling the HDPE conduit 
can put a pull tape (up to 5000 lb) into the conduit for extra money.  If I 
only have to add pull tape to bored sections under driveways, I can do that 
easily with a fish tape.  Then I'd use a capstan to pull the whole run through.

For background, I'm looking at a relatively small project: about a mile.  
That's why one machine that plows and drills seems attractive on the 
surface....and why more cost for a conduit with a pull tape already in looks 
better to me than a blowing machine.

On depth I don't really know for sure.  Good question.  I have a few different 
conflicting sources.

  You can definitely plow in conduit. If you're going to do it that way you 
would want to look into blowing in the fiber after all the conduit is placed. 
This is a nice approach because you can splice/couple conduit very easily so 
the switch between plow and drill is not a big deal. Then once all the conduit 
is in the ground and coupled together, you can blow fiber in through the whole 
run in one shot. The blowing equipment is fairly expensive but  I would think 
you can rent that.  

  Do you have a requirement for how deep you need to be placing your cable? A 
small plow like that could pull short sections of conduit at 18" or maybe up to 
24" deep. If you need to go any deeper you'll need a much larger plow.

    That's good advice, thanks.

    I see what you're saying about laying out the whole run at the first 
obstruction and what a pain that would be.

    I pictured plowing in an HDPE conduit with a pull tape in it rather than 
plowing cable directly into the ground.  So I'd be pulling the entire run off a 
reel trailer either way.  At the moment this project exists mostly in my 
imagination so if plowing in conduit is a dumb idea, this would be a perfect 
time to tell me. :) 





      The discussion about whether you should drill or plow a certain stretch 
is subjective. Remember that every time you plow and need to go under an 
obstacle you have to figure 8 the whole cable run, or cut and have a splice 
point there. That can be a lot of labor if you're trying to keep a long run 
intact. Personally,  when we are running in a rural area, if we have driveways 
every 200-400ft we drill that area. If we can go 800ft or more without 
obstructions then we plow that.
