Key highlights
- Indiana soybean harvest typically runs September through October and corn follows in October and November. The pre-harvest inspection window is August and early September, when there is still time to schedule repairs properly.
- A structural crack found during an August inspection is a scheduled repair. The same crack found during the first pass through the field in October is a breakdown that takes the machine out of service at peak season.
- Inspect knife guard mounts, row divider attachment points, and feeder house side sheets at the lower pivot. These are the highest-stress weld points on a combine and the most common locations for fatigue cracks.
- Any crack that has propagated into the base metal, sits at a joint intersection, or has widened since last season needs a professional welder before the machine runs at full harvest load.
- When contacting a mobile welder, specify the equipment type, component name, approximate crack length, and your county. A description like "left feeder house side sheet, three-inch crack from the lower pivot" gets a faster and more accurate response.
Why pre-harvest welding inspection matters
Most pre-harvest equipment inspections focus on belts, chains, and bearings. Weld integrity is the step most likely to be skipped and most costly to miss. Indiana's soybean harvest typically runs September through October. Corn follows in October and November. That puts the pre-harvest inspection window in August and early September. A structural crack on a combine header or auger frame that holds during light off-season work can propagate under full harvest load and fail when the machine is running at capacity. The difference between finding a crack in August and finding it during the first pass through the field in October is real. A planned repair before harvest is a scheduled job with time for proper assessment and weld preparation. The same repair during active harvest is a breakdown that takes the machine out of the field when every day of downtime costs the operation. Welds are easy to overlook because cracks don't announce themselves the way a worn belt or a bad bearing does. They sit quietly in the steel until the load exceeds what the weakened joint can hold. That's why a dedicated welding walk-around belongs on the pre-harvest checklist alongside the mechanical inspection.
Combine and header frame inspection checklist
Header frame
- Knife guard mounts where the guards attach to the cutter bar. These are stress concentration points that crack from repeated impact during cutting. Look for hairline fractures along the weld bead at each guard mount.
- Row divider attachment points where the dividers bolt or weld to the header face. Check for cracks radiating outward from bolt holes or running along the attachment weld.
- Wing section connection welds on flexible draper headers. Inspect both the hinge points and the structural welds where wing sections meet the center frame.
Feeder house
- Side sheets at the lower pivot point. This is the most common stress crack location on older combines. Inspect both sides carefully for hairline cracks running from the pivot mount toward the floor.
- Chain housing frame welds where the feeder chain housing meets the structural frame.
- Floor attachment welds where the feeder house floor connects to the feeder throat. Crop material buildup can hide cracks here, so clean the area before you inspect.
How to tell surface damage from a structural crack
Not every mark on a weld is a problem. Paint cracking and surface corrosion lines that haven't penetrated the base metal are cosmetic issues you can monitor. A structural crack looks different. It runs across the weld seam or into the base metal, shows up at a joint intersection where two structural members meet, or has visibly widened since last season. If a crack has grown or changed direction, it needs professional assessment before the combine runs at harvest load.
The combine header frame carries the most concentrated mechanical stress during harvest operation. These are the weld points to inspect before the machine runs.
Auger and grain handling equipment inspection
Grain auger
- Flight-to-tube attachment welds along the auger tube. Flights can separate from the tube under heavy grain flow. Look for gaps or visible cracks at the weld line where each flight meets the tube wall.
- Auger boot weld where the boot casting meets the tube. A failure here causes grain loss and can jam the entire auger during operation.
- Intake flighting attachment at the lower end of the auger. This area takes constant abrasion and impact from grain entering the system.
Grain cart
- Frame corner welds and diagonal bracing welds. Grain carts run over rough field terrain under heavy load, and the corner joints absorb the most cyclic stress.
- Auger attachment welds where the unloading auger mounts to the cart frame.
- Running gear welds at the tongue attachment and axle mounts. A tongue weld failure while towing a loaded grain cart is a serious safety issue, not just a production problem.
Portable grain handling equipment
- Vertical auger stand welds at the hitch point and base.
- Conveyor frame joint welds where sections connect.
Grain augers and grain carts take heavy loads over rough ground during harvest. The weld points below are where failures most commonly develop.
Field implements and equipment hitch inspection
Hitch and drawbar
- 3-point hitch frame welds at the category pins and lower link attachment points.
- Drawbar weld at the tractor frame mount. A cracked drawbar under towing load is one of the most dangerous equipment failures in farming. If you find any crack here, stop using the equipment until it's repaired.
- Quick-hitch frame welds if your operation uses a quick-hitch system.
Field cultivator and planter frames
- Toolbar end cap welds and section attachment welds. C-shank attachments can work loose over a season, and the resulting vibration stress transfers to the toolbar frame.
- Folding section hinge welds on wide-span implements.
- Planter main frame welds at row unit attachment points. Less critical than hitches, but worth a visual check during your walk-around.
Equipment hitches and drawbar welds are safety-critical. A failed drawbar or 3-point hitch attachment during field or road operation is a serious hazard. Any visible crack on a hitch weld point should be assessed by a professional welder before the machine goes back to work.
DIY vs. call a pro: when a crack needs a mobile welder before harvest
Surface cracks you can monitor
Paint oxidation lines, surface rust that hasn't penetrated the base metal, cosmetic weld spatter chips, and minor surface wear on implement frames that aren't under primary structural load. You can grind these smooth, watch them between seasons, or address them on a flexible schedule.
Structural cracks that need a professional before harvest
A crack propagating across a weld seam or into the base metal. A crack at a joint intersection where two structural members meet. Any crack on a load-bearing member that has widened or grown since last season. Any crack on a hitch, drawbar, feeder house structural frame, or auger boot. If you have welding skills and equipment, patch welds on non-critical panels and cosmetic repairs are reasonable DIY work. Structural repairs on load-bearing components require proper weld preparation, correct filler metal, and a welder who knows what the joint needs to hold under full harvest load. That's not a knock on farm welding skills. It's a recognition that structural joints on equipment running sixteen-hour harvest days need to be done right. One more factor: timing. Structural repairs scheduled four to six weeks before harvest leave room for assessment, scheduling, and a re-inspection before the machine runs. The same repair done the week before harvest or during active cutting is a rush job with a different price and fewer scheduling options.

Some cracks on farm equipment can wait. Others need a qualified welder before the machine runs at harvest load. The difference comes down to where the crack is, how deep it goes, and whether it's growing.
Describe your equipment issue →What to tell your welder
When you contact a mobile welder about a farm equipment repair, these are the details that help them assess the job accurately:
- Equipment type and approximate year or model
- Component name and location, using specific terms from your inspection (e.g., "left feeder house side sheet at the lower pivot point," not "somewhere on the combine")
- Approximate crack length and whether it runs horizontal, vertical, or at an angle
- Whether the equipment is in a machine shed or needs field service
- County and general area where the equipment is located
Here's what a useful description looks like: "The combine is a 2017 model. There's a crack on the left feeder house side sheet, about three inches long, running from the lower pivot mount toward the floor. It looks structural. The combine is in our machine shed in Hendricks County." The more specific you are about the component and the crack, the better a mobile welder can prepare for the job before they arrive. Describe your welding problem below. Include the equipment type, the component name, and the crack location. We'll connect you with a Central Indiana mobile welder who can assess and schedule the repair before harvest.

Frequently asked questions about emergency welding in Fort Wayne
What welds should I check on my combine before harvest?
Inspect the combine header frame at the knife guard mounts and row divider attachment points. On the feeder house, check the side sheets at the lower pivot point, the chain housing frame welds, and the floor attachment to the feeder throat. The lower pivot area on the feeder house is the most common location for stress cracks on older combines. Look for cracks that run across weld seams, appear at joint intersections, or have widened since last season.
When should I hire a welder for a crack on farm equipment rather than attempt a DIY weld?
Hire a professional for any crack on a load-bearing component: hitches, drawbars, feeder house frames, auger boots, and grain cart tongue attachments. Cracks at joint intersections or cracks that have propagated into base metal also need professional repair. DIY welding is appropriate for cosmetic surface repairs on non-structural panels if you have the right equipment and filler metal. When the weld carries harvest-level load, proper preparation and technique matter too much to shortcut.
How do I find a mobile welder for farm equipment near Indianapolis?
Most mobile welders in the Indianapolis area serve commercial and construction clients, so finding one comfortable with agricultural equipment takes some filtering. WeldingEmergency.com connects farm operators with mobile welders serving Central Indiana counties including Hendricks, Boone, Johnson, and Morgan. Describe your equipment and the issue and we'll match you with a local welder who can reach your farm or machine shed.
How much does pre-harvest farm equipment welding cost in Central Indiana?
Cost depends on the job itself. The main factors are repair complexity, whether the welder comes to your field or you bring the equipment to a shop, timing (pre-season scheduling vs. mid-harvest emergency), and the base metal involved. Mobile welding typically includes a trip charge plus hourly labor. Shop rates run lower per hour, but you'll need to transport the equipment. For a realistic estimate, describe the repair with the equipment type, crack location, and your county.
How far in advance should I schedule welding repairs before Indiana harvest season?
Indiana soybean harvest typically begins in September, with corn following in October. Schedule your pre-harvest welding inspection and any needed repairs by August 1 at the latest. That gives your welder time to assess the job, source the right filler material, complete the repair, and leave you a window to re-inspect before the machine runs at full load. Mobile welders in Central Indiana get busier as harvest approaches, and early scheduling means better availability and less cost pressure.
