Hay Equipment Repair in Iowa — Mower Conditioners, Rakes, Tedders & More

Hay doesn’t wait. When the forecast gives you three dry days and the mower conditioner grenades a gearbox on day one, the window closes with the hay still standing — and every hay producer in central Iowa has lived that day. Ames Hydraulics does hay equipment repair across the hay line: mower conditioners, discbines and haybines, rakes, tedders, self-propelled windrowers, and the wagons and running gear that carry it all home. (Balers have their own page — see baler repair — because they earn it.)

Mower Conditioners: Where Hay Season Dies

The discbine is the hardest-working machine in the hay line and the most common reason hay equipment repair calls come in at 7AM. Cutterbar modules run hot and seize, shear hubs do their job and then some, conditioner rolls lose their timing, and the driveline from the tractor takes shock loads every time a disc finds something the field was hiding. We rebuild cutterbar modules, replace and time conditioner rolls, rebuild the gearboxes (main, bevel, and module — the same gearbox bench that does everything else), and repair the swing frames and hitches that crack from years of headland turns. Sickle-bar haybines get the same treatment — wobble boxes rebuilt, knives and guards renewed, and the frames welded where forty years of fatigue shows.

What We Fix Across the Hay Line

• Mower conditioners & discbines — cutterbar modules, conditioner rolls, gearboxes, drivelines, frames
• Rakes — wheel rake arms straightened and re-toothed, rotary rake gearboxes and cam tracks rebuilt, hydraulic fold cylinders resealed
• Tedders — rotor gearboxes, tine arms, and the fold hydraulics that quit at the worst time
• Self-propelled windrowers — hydrostatic drive diagnosis, wheel motors, header drive, and A/C-off-the-record welding on the header frames
• Hay wagons & running gear — spindles, hounds, reaches, and rotted racks rebuilt (running gear is a specialty here)
• Bale handling — grapples, spears, and accumulator hydraulics

Between-Cutting Turnaround

Hay gives you natural repair windows — the two or three weeks between cuttings — and that’s how we schedule hay equipment repair: machine in right after the cutting wraps, torn down and quoted inside two days, back on the yard before the next window opens. In-season breakdowns get triage treatment, because we know exactly what a rained-on windrow costs. Text photos of the failure to 515-292-2599 and we’ll tell you same-day whether it’s a field fix, a fast shop job, or a parts hunt — and if it’s a parts hunt on an orphaned machine, our machine shop can often make the part that no longer exists.

The Off-Season Is the Cheap Season

Every fall, the smart hay outfits send the whole line through: cutterbar oil changed and modules checked, conditioner roll timing verified, every gearbox drained and inspected, rake teeth counted, chains and drivelines measured, and the welding list knocked out while nothing is urgent. Winter hay equipment repair costs the same labor rate but zero downtime — and the machine that got the winter once-over is the one that doesn’t blow up in June. Free pickup within 60 miles of Ames for anything that rolls or can be trailered. 210 Freel Dr, Ames — Monday through Friday, 7AM to 5PM.

Running Gear and Hay Wagons: the Forgotten Fleet

Every hay operation runs a fleet of wagons older than the people driving them, and running gear is quietly one of our specialties. Spindles wear egg-shaped and get turned or replaced, hounds and reaches crack where seventy years of turning stress concentrates, bolster stakes wobble loose, and the wooden racks rot from the deck down. We rebuild running gear the honest way — straighten and reinforce what’s sound, replace what isn’t, and repack every hub while it’s apart — because a wagon that follows straight and stops available is worth five that are “probably fine.” A loaded rack wagon with a seized wheel bearing on a July highway is nobody’s idea of a good time, and a bearing check is minutes per wheel during any winter hay equipment repair pass.

Why a Hydraulic Shop Fits Hay Work

Modern hay tools are hydraulic machines: fold circuits on rakes and tedders, header float and drive on windrowers, pickup lifts, bale grapples, and the hydrostatic drives on anything self-propelled. When the wing won’t fold or the header won’t float, the fix is our home turf — cylinders resealed on the bench, valves diagnosed instead of swapped, hoses built while you wait, and hydrostatic systems tested rather than guessed at. Add the machine shop for the obsolete bushings and shafts on older iron, and the welding floor for everything that cracks, and one stop covers what usually takes three. That’s the practical case for bringing hay equipment repair here rather than splitting it between a dealer, a hose shop, and a welder — the whole failure gets fixed in one place, quoted in writing before the work starts.

Common Hay Equipment Questions

Can you get parts for an older discbine? Usually — cutterbar internals for the common New Holland, John Deere, Kuhn, and Case IH lines stay available long after the machine is “obsolete,” and what can’t be bought can often be machined. My rotary rake clatters — worth fixing? Almost always; cam track and arm bearing rebuilds run a fraction of a replacement rake. Do you make field calls in season? Within 60 miles of Ames, yes — and half of in-season hay equipment repair turns out to be field-fixable once someone who knows the machine looks at it. What should I check before first cutting? Cutterbar oil, knife condition, roll timing, every driveline shield, and every tire — twenty minutes that saves the season’s first good weather window.
