Heavy-duty steel hinge folding system for fast field-to-road transport. Folds tight, locks solid.
Long Row Units
Extended 36" deck plates run flatter to the ground, pulling in more crop with less loss.
Aggressive Deck Plates
Precision-spaced plates aggressively strip ears while minimizing butt shelling and kernel damage.
Poly Snouts
Durable polymer bonnets and snout tips reduce weight and resist corrosion season after season.
Stalk Stompers
Industrial-strength spring stompers on every row unit. Easily removed when conditions don't require them.
Auto Height Control
Integrated sensor maintains optimal head height across uneven terrain. Set it and forget it.

Mainero MDD-200 IRT
Don't Take Our Word For It
We put the MDD-200 head-to-head against the biggest names in the industry. Same field. Same conditions. The numbers speak for themselves.

Row Independence
Most corn heads require you to follow the planted rows exactly. The Mainero MDD-200 doesn't care which direction you're going.

Angled harvestingNot recommended
Why it matters: Row-independent harvesting means you're not locked into following planted rows. Run diagonal, cross-rows, or harvest fields at different spacings — all without swapping headers. Less downtime, more acres per day.

IRT Knife Rollers
Mainero's IRT rollers were designed specifically for US harvest conditions. Longer contact, cleaner processing, less grain loss.

Ear removal zone27"
Why it matters: Longer rollers mean more contact time with the stalk. Ears are pulled down slower — reducing butt shelling and kernel damage without sacrificing ground speed. The IRT design was purpose-built for higher-moisture US conditions.

Snout Design & Durability
Mainero is the only corn head on the market with stainless steel snouts. Not poly. Not painted steel. Stainless.

DesignStandard width
Pivoting tipsFixed
Corrosion resistanceGood
Why it matters: Poly snouts crack, warp, and degrade over time. Stainless steel won't corrode and lasts dramatically longer. The narrow open-side design lets stalks ease into the gathering chains without shock — reducing ear drop in down or tangled crop.

Gathering Chain System
The MDD-200's double-offset sprocket and V-configuration gathering chains create the widest entry channel in the industry.

Drive systemStandard chain drive
MaintenanceManual adjustment
Why it matters: The V-shaped chain layout with double-offset sprockets creates a broad funnel that guides stalks in — even when misaligned from wind, lean, or cross-row harvesting. Oil bath drive means no daily greasing and significantly longer chain life.

Deck Plates
Hydraulic-adjustable deck plates with a clear position indicator let you dial in spacing on the fly — from the cab.

Why it matters: Conditions change across a field — moisture, stalk diameter, standability. Hydraulic adjustment from the cab means you're always optimized without stopping. The clear visual indicator eliminates guesswork during walkarounds.
Build Quality
Mainero has been building corn heads since 1952. The MDD-200 is an all-steel machine manufactured in a 375,000 sq ft facility running 24/7.

Why it matters: An all-steel build with stainless steel snouts, individual torque limiters on every row unit, and factory-level CNC precision means less downtime, fewer replacements, and a machine that holds its value. This isn't assembled — it's engineered.
