Grain Handling Equipment Repair in Iowa — Augers, Bin Sweeps & Grain Legs

Harvest capacity isn’t set by the combine — it’s set by whatever piece of grain handling equipment breaks first. A dead leg at the elevator, a bin sweep that won’t crawl, or a transport auger with a wiped gearbox stops the whole chain, and suddenly trucks are waiting on a machine that should have been fixed in July. Ames Hydraulics repairs grain handling equipment across central Iowa for farms and commercial sites: augers, bin sweeps, grain legs and drags, unload systems, and the drives and hydraulics behind all of it.

Augers: the Backbone That Gets No Respect

Transport and swing-away augers do brutal work and get parked wet, and the failure list writes itself: flighting worn knife-thin at the intake, tube wear-through, gearboxes run dry, winch and lift cable damage, and undercarriage cracks from moving them loaded. We rebuild all of it — flighting replaced or extended, tubes patched or re-sectioned, gearboxes rebuilt on our bench, and the running gear made roadworthy again. The full story lives on our auger repair page; the short version is that a tired auger is almost always worth fixing, and the measurements tell us fast when it isn’t.

Bin Sweeps, Legs, and the Commercial Side

• Bin sweeps — drive wheels rebuilt, gearboxes and backboards restored, flighting renewed, and the sump-side hardware freed up (always with lockout respected — sweep work follows bin-entry rules, no exceptions)
• Grain legs — head and boot section repair, cup and belt replacement, bearing changes on the machinery our welding and rigging capability actually reaches, and the ladders, platforms, and guards that keep inspections clean
• Drag and chain conveyors — paddles, chains, liners, and drive sprockets
• Unload and stirring systems — power sweeps, unload augers, stirring machine down-augers and track drives
• Dump pits and hydraulics — pit conveyor drives, hoist cylinders on dump grates, and truck probe hydraulics

Hot Bearings Are Fire Math

Grain dust makes bearing failures a different class of problem — a hot bearing on a leg or drag isn’t a repair ticket, it’s an ignition source sitting in suspended dust. Commercial sites know this from their insurance audits; farm sites should treat their own legs and drags the same way. Our grain handling equipment inspections run temperature checks on drive and tail bearings, look at belt tracking and cup clearance inside legs where rubbing generates invisible heat, and flag the wear that becomes a fire before it becomes a breakdown. It’s the same discipline our conveyor belt repair work applies at grain sites, pointed at the vertical machinery.

July Is the Deadline

Every piece of grain handling equipment in Iowa has the same service window: after planting, before harvest. Augers, sweeps, and leg components that reach the shop in June and July get rebuilt without anyone sweating; the same work in October happens with a line of loaded trucks watching. Walk the system in early summer — spin what should spin, grease what takes grease, and text photos of anything questionable to 515-292-2599. Same-day read, written quote, and free pickup within 60 miles of Ames for anything trailerable. 210 Freel Dr, Ames — Monday through Friday, 7AM to 5PM.

Gearboxes and Drives: Where Grain Systems Actually Fail

Strip away the sheet metal and most grain handling equipment is gearboxes and drives doing repetitive work in dust: the right-angle box on the auger, the sweep’s wheel drive, the leg’s reducer, the drag’s head sprocket shaft. They fail from the same two causes — run dry or run wet — and both show up in the oil long before they show up as a seized shaft in October. Our gearbox bench rebuilds all of them: bearings, gears, seals, and shafts, including the orphaned boxes on equipment whose builder disappeared decades ago. Belt and chain drives get the same treatment — sheaves, sprockets, and tensioners restored so the drive transmits power instead of slip-polishing itself. If you drain one gearbox this summer and the oil comes out glittering, drain them all; wear runs in fleets, because the whole system was installed the same year and greased on the same schedule.

Farm Bins and Commercial Sites: Same Iron, Different Stakes

A farm with three bins and an elevator with three million bushels run the same machinery at different scale, and we serve both. Farm work is usually seasonal and forgiving — a sweep rebuilt in July, an auger gearbox between wheat and beans. Commercial grain handling equipment work runs under audit pressure: insurance loss-control visits, OSHA combustible-dust attention, and the paper trail that proves the hot-bearing program is real. We fit both worlds — written condition reports and documented repairs for the sites that need the file, and straight talk plus a fair invoice for the farm that just needs the sweep to crawl again. Rigging-wise, we’re honest about reach: boot-level and ground-level leg work, drags, and everything trailerable is ours; hundred-foot head-section work needs a millwright crew with a crane, and we’ll say so rather than improvise at altitude.

Common Grain System Questions

My auger flighting is knife-edged — repair or replace? Measure the flight edge: under half original thickness at the intake, re-flight the intake section; wear past mid-tube usually means a new tube assembly wins on math. The bin sweep stalls halfway around — motor or drive? Usually the wheel drive slipping, not the motor — a rebuild is routine. Can you rebuild leg cups and belting? Yes, at boot level with the belt dropped — and belt splice condition gets checked while it’s down. When should grain handling equipment get its annual look? June — after planting, before the pre-harvest rush, when parts lead times are short and nobody is desperate.
