Rotary Cutter & Batwing Mower Repair — Ames Hydraulics

A rotary cutter takes a beating no other implement does — it hits stumps, rocks, and fence posts at full speed, and something has to give. Ames Hydraulics does rotary cutter repair and batwing mower repair for farms, acreage owners, and county crews across Central Iowa: gearboxes, blades and spindles, decks, drivelines, and the hydraulics on folding batwings. Free pickup within 60 miles of Ames.

What Breaks on a Rotary Cutter

The gearbox is the first casualty — a hard hit or low oil and it leaks, whines, or seizes. Blade pans, spindles, and blades bend and break on rocks and stumps. The deck cracks and wears thin, especially at the sides and the top skin. Driveline components — the PTO shaft, u-joints, slip clutch, and shear bolts — take the shock and fail. And on batwing and folding cutters, the wing hydraulics, cylinders, and hoses leak or lose power so the wings won’t lift. A complete rotary cutter repair covers the gearbox, the cutting components, the deck steel, and the driveline together.

What We Repair

• Gearboxes — reseal, rebuild, or replace the deck and splitter gearboxes
• Blades, blade pans, and spindles — replaced and balanced
• Cracked and worn decks — welded, plated, and reinforced top and bottom
• Drivelines — PTO shafts, u-joints, slip clutches, and shear-bolt hubs
• Batwing wing hydraulics — lift cylinders, hoses, and valves so the wings fold and hold
• Wheels, tires, hubs, and axles on the deck and wings

Everything From 5-Foot Cutters to 15-Foot Batwings

Whether it’s a small 3-point rotary cutter behind a compact tractor or a 15-foot batwing mowing ditches and CRP, the failures are the same and the fixes are the same skills. Batwings add the wing hydraulics and more driveline, all of which we handle. If you also run a flail mower or a boom mower, we fix those too.

All Brands

Bush Hog, Land Pride, Woods, John Deere, Rhino, Servis, Modern, and the rest — independent service on whatever you own, with gearboxes, blades, and driveline parts sourced to match. A rebuilt gearbox and a welded deck bring most cutters back for a fraction of a new one.

Fix It Before Mowing Season and Free Pickup

Get the gearbox checked and the deck welded up before the grass and brush take off, and you’ll mow all season without a breakdown. Pickup and delivery are free within 60 miles of Ames — text a photo of the cracked deck or leaking gearbox to 515-292-2599 and we’ll tell you the same day what your rotary cutter repair needs and what it will cost.

Signs Your Cutter Needs Repair

The common tells that a rotary cutter repair is due: the gearbox is whining, leaking, or running hot (low oil or worn gears), the cut is rough or the deck vibrates (bent blades, spindles, or an out-of-balance pan), you can see cracks spreading in the deck top or sides, the driveline clunks or the slip clutch slips (worn u-joints or clutch), or on a batwing the wings won’t lift or won’t stay up (hydraulic cylinders or hoses). A hard hit on a stump or rock is often what starts it — get it checked before the gearbox or deck lets go completely.

Rebuild Beats Replacement

A rebuilt gearbox, new blades and spindles, a welded and re-plated deck, and gone-through wing hydraulics bring a beat-up cutter back for far less than a new one. We handle the gearbox, the cutting parts, the deck steel, and the hydraulics in one stop, and we’ll give you honest numbers on a targeted fix versus a full batwing mower repair so you can decide.

One Shop for the Whole Machine

What sets us apart on a cutter is that the gearbox, driveline, hydraulic, and welding work all happens under one roof. Most shops send the gearbox one place, the hydraulics another, and the welding to a third — which means more hauling, more waiting, and no one who sees the whole machine. We diagnose it, rebuild the driveline and hydraulics, weld up the steel, and put it back together as one job. That’s faster, cheaper, and the repair holds because it was done by people who understand how the whole cutter works together. It’s why farms across Central Iowa bring us their rotary cutter repair instead of chasing three shops.
