Great question… there is a few key differences.
With a chute, you can drop in multiple conduit… BIG advantage, sometimes we put
in 2x 1.5” or 1.5” plus a ¾”. One for fiber, one for power if a customer wants
power at a driveway (gates, light, sensor)
If you are required to put in a “caution tape”, must use a chute…
If you are going in a straight line, pulling is great. Less HP needed.
Many or sharp curves… use a chute
Or plan for adding couplers
If soil conditions are soft, chute works great. No breakage or pipe stretching.
If soil conditions are packed/hard… add more horsepower/traction for a chute
Using a pull blade to run the path without product in hard ground on the first
pass, then go back with the pull blade on the second pass and pull the product.
If you have roots, the pull blade with serrated teeth do a great job. I
haven’t seen a serrated edge on a chute.
Friction is not your friend when pulling…
And size of the machine… when using a chute, you need more traction / weight /
HP.

Subject: [AFMUG] Pull blade vs chute blade
Are there situations for which one is better than the other? I know pulling
limits your distance, I'm not sure otherwise.
