My take on bucket line vs suction dredges shifted after a muddy job

I always said bucket lines were too slow and stuck with suction rigs for everything. But last month on a job with thick clay, my suction dredge kept clogging every hour. We switched to a bucket line and finished the cut in half the time with less downtime. Now I won't touch a suction dredge for heavy soils, no matter what the specs say. Sometimes the old way just works better.

So you find the bucket line just powers through where suction chokes? Makes me wonder how many jobs we over-engineer because the specs favor newer tech. Like with that thick clay, the buckets probably just smash it apart while suction tries to swallow a whole chunk. Seen similar stuff with old cable plows versus fancy vibratory ones in rocky ground. Sometimes the simple tool that just forces its way through beats the smart one that has to stop and think.

Ever notice how specs love to ignore the messy real world? @wesley_jackson nailed it, we overthink this stuff and then the simple tool wins. Guess sometimes you just need a dumb brute force method to get the job done.

But sometimes that brute force method makes a bigger mess to clean up later... like yeah it gets through the clay but then you're dealing with way more spoil. @keithyoung maybe the suction is smarter if you factor in the whole job, not just the digging part.
