I took on a 3 acre pond near Gadsden that had been silting up for 20 years. The owner said three other operators turned it down because the access road was too narrow. I spent two days just widening the path with a borrowed dozer. When I finally got my 6 inch dredge in there, I pulled out about 400 yards of muck in the first week. The water clarity went from 6 inches visibility to almost 3 feet by the third week. Has anyone else taken a slim access job that ended up being a decent payday?
The cable-laid line kept kinking on me during a tight bend near the Norfolk port channel. I swapped to a braided line from a buddy’s recommendation and it ran smooth for the whole 8 hour shift with zero snags. Anyone else have better luck with one type over the other on tricky jobs?
I run a 12-inch dredge up on the Snake River and that old cutterhead was so worn the teeth barely bit into the material anymore. Put a new one on with fresh carbide tips and the production jumped from about 80 yards per hour to 115 on the first pass. Has anyone else noticed a big difference after switching cutterheads on an older machine?
Was out on a job near Lake Havasu last spring when the suction line started cavitating loud enough my deckhand heard it from the wheelhouse. Turns out I never adjusted for the shallow water during the dry season and was pulling air the whole time.
I was running a 12 inch cutterhead suction dredge on a canal cleanup outside Baton Rouge back in June. For months I kept fighting with the pump clogging every 20 minutes and the production numbers were garbage. A older operator named Dale came by to drop off some spare parts and watched me for maybe 5 minutes. He asked why I was running the cutterhead at full RPM in that heavy clay mud. I told him that's just how I always did it. He laughed and said I was basically churning butter instead of cutting. He had me drop the speed by almost half and suddenly the material flowed smooth as glass. No more clogs and we moved twice the yardage that shift. Has anyone else found that slower cutterhead speed actually works better in sticky material?
I put a new style of cutterhead teeth on my old Ellicott 370 last month, the kind with the hardened inserts. My goal was just to get through some packed clay a little faster, maybe save a few hours. Instead, my production rate jumped almost 40% on that job near the river bend. The downside was I had to clean the ladder twice as often because the finer material clogged the suction inlet. Has anyone else run into that trade-off with aggressive cutter upgrades?
Had to pick between a cutter suction and a trailing suction hopper dredge for clearing out silt on the Mississippi near St. Louis last month. Went with the cutter because the channel was too narrow for the trailing setup to swing around. Worked great for the first 2 weeks but the cutter head kept getting clogged with tree roots. Anybody here run into that issue on river jobs or should I have gone with the trailing rig?
I was swapping stories with this guy who's been running dredges since the 80s down in Mobile Bay last week. He told me most guys ignore the high pitch whine and think it's just the engine working hard. He said I should treat that sound like a check engine light, not background noise. Hit me because I've been dealing with inconsistent production numbers for months and just blamed the material. He walked me over to my pump and showed me tiny pitting marks I never noticed before. Now I'm second guessing every time I hear that whine and wondering how much downtime I could have saved. Has anyone else here had a mechanic or old timer teach them a trick by ear that made a big difference?
For about 2 years I always ran my 12 inch dredge at max RPM because I thought that meant more production. Then I noticed my slurry density was actually dropping and I was burning through wear parts way faster. Has anyone else found a sweet spot with slower cutterhead speed for certain materials?
Bought a supposedly rebuilt 6-inch pump off a guy in Baton Rouge and didn't check the wear plates before loading it on my trailer. Has anyone else gotten burned buying used gear from those online marketplace deals?
I was running a cutterhead dredge on the Mississippi near Baton Rouge last Tuesday, and I noticed my ladder wasn't retracting smooth. Pulled it up to check and found this thick crusty layer inside the hydraulic tubes. Looked like some kind of sediment mixed with old oil. My buddy Mike who's been doing this 15 years said it's from not flushing the system after a big sand run. He showed me how to use a pressure washer attachment to clear it out in about 20 minutes. Saved me from having to pull the whole ladder and replace seals which would've cost like 800 bucks. Has anyone else seen this kind of gunk build up in their equipment?
I was grabbing some fittings last Tuesday and this younger operator was telling the counter guy that a pump is a pump and you're just wasting money on brand names. That kind of talk just rubs me the wrong way because I've spent 22 years running dredges on the Mississippi River and I can tell you for a fact that cheap impellers fail twice as fast when you're digging through sand and gravel mix. My crew and I ran a job near Baton Rouge where we switched from a standard pump to a heavy duty one and our downtime dropped from about 8 hours a week to maybe 2. The difference is in the wear plate thickness and the way the casing handles the slurry, not just the name on the side. So has anyone here actually run both budget and premium pumps side by side on the same material?
Last month I had a 2 acre pond to clear out, mostly silt and some hardpan. Rented an Ellicott 370 on a buddy's recommendation. That thing chewed through the hardpan like butter, no clogging. Tried a Mud Cat 450 on a similar pond 3 years back and I was fighting the cutter head every 20 minutes. Has anyone else had that kind of experience switching between brands?
It wrapped around the suction pipe so tight we had to call in a diver for 3 hours to cut it loose, has anyone else ever snagged something completely random that shut everything down?
I was delivering a rebuilt hydraulic pump to a crew working the Houston Ship Channel and watched a cutterhead dredge chew through what looked like solid clay. Then about 20 minutes in they hit a big pocket of sand and slurry started shooting out sideways from the ladder. The operator just throttled up and kept going like nothing was wrong. Anybody else ever have the material change that fast on a job and still keep the pump from cavitating?
Had a job near Baton Rouge where a wad of roots kept jamming my 8-inch cutterhead every 20 minutes, so I tried backflushing with a garden hose shoved into the discharge port (just a dumb idea I had at 3am). It actually cleared the debris in under 2 minutes and saved me from pulling the whole pump assembly apart. Anybody else got a weird field fix that somehow worked better than the manual says?
I watched a project on the Mississippi last summer drag on 3 extra weeks because the hydraulic unit couldn't handle the packed sand, even though everyone swore it would. Has anyone else found cutter suction pulls ahead in harder material or is it just me?
Guy named Dale, been dredging since the 80s. Told me to stop rushing the suction swings on the Barge 7 job near Baton Rouge. I was pushing too hard, clogging the cutterhead every 45 minutes. After I slowed down by 20%, we ran clean for a full 8-hour shift. Anyone else get humbled by a simple tip like that?
Last August I hit a submerged log near Baton Rouge. Tore up the cutterhead bad. Three full days of welding repairs. Lost a $12,000 contract because of downtime. The current was running faster than normal that week too. Made everything harder. Anyone else deal with random debris that just appears out of nowhere?
This was two weeks ago on a Tuesday morning. I was about 30 feet into a 200 foot run of 3/4 inch cable on a bank job in Memphis and my cable shear just gave up. Snapped right at the hinge. Never seen that before. Had to drive 20 minutes to a rental place to get a backup and wasted half the morning. The old one was a Klein I've had for maybe 5 years. Anyone else had a tool just break at the worst possible time?
I'd been running my 8-inch dredge for about 6 months on a pond near Baton Rouge and kept getting uneven material. A retired guy walked up and said my cutterhead was pitched too steep, costing me efficiency. After I adjusted it down by 5 degrees, my production jumped almost 30% - has anyone else had a specific feedback fix like that?
I switched to running my cutterhead at 75% power back in August on a job in Green Bay. The difference in fuel burn was around 12 gallons per shift, and the wear bars on the ladder still look fresh. Got the tip from an old timer who said most people just jam it wide open and waste energy. Anyone else find a sweet spot below max RPM that actually saves money?
Kept tripping on my bucket ladder circuit. Third time I finally checked the cable twist instead of swapping parts. Turns out a kinked shore cable was pulling more amps than usual. Anyone else deal with underwater cable snags causing phantom draws?
I was working a job on the Sabine River last month and spent almost 3 hours clearing wrap off my cutterhead. It was that sticky soft mud everyone says is easy to push through. The problem is guys don't talk about keeping your RPMs low in that mud or you'll wrap it up bad. How do you all handle soft mud without getting wrapped every 20 minutes?
I used to rely almost completely on my depth finder and just go by the numbers. Then about 4 years ago I switched to running a towed sonar array behind the dredge and it changed everything. The old method was fine for basic depth but it missed all the subtle changes in the bottom type. Now I can see clay turning to sand before I even hit it, which saves me from chewing up a cutterhead. A guy up near Baton Rouge told me to try it after I burned through a set of teeth in one shift. Has anyone else made the switch and found the same thing or do you think the old way still works better for certain conditions?
