Disc harrows

AMCO builds folding and standard (non-folding) double offset tandem disc harrows for seedbed preparation. The F15 and F15B fold their flexwings to follow field contours; the F17 is the non-folding option.

Wheel offset harrows

AMCO groups its pull-type wheel offset harrows by blade spacing: 9″ (D41, F41, F42), 10½″ (J41 to J44) and 12½″ (G2). AMCO says they cut and size residue, break up clumps and loosen packed soil.

3-point lift harrows and grader blade

AMCO says it has a 3-point disc or lift harrow for commercial operations, large farms and hobby farms alike. The Z-Blade grader blade rides on the same 3-point hitch for road and turn-row work.

Ditchers and water management

AMCO builds rotary ditchers and disc plows to move water off fields, fix pivot and tile ruts, and build terraces. Ditchers come in vertical, offset and the larger Dominator body styles.

AMCO history

William A. Alexander founded Alexander Manufacturing Company in October 1947. Its main product was a 3-point, eight-blade, reversible Bush & Bog built for Ford Motor Company. Tandems, fold-overs and lift offsets followed.

AMCO began expanding its sales territories and product lines after the company changed ownership in the early 1950s. It became known for triple-lip sealed, greaseable bearings, including the Protect-O-Shield bearing, which it says made it the first to offer a two-year warranty on this type of bearing system. The company moved to Yazoo City, Mississippi in 1963. Today AMCO is part of the Yetter Manufacturing Company family.

How AMCO builds its harrows

30-day performance promise

If new AMCO equipment does not perform as promised in its first 30 days, AMCO says it will repair, replace or buy it back.

AMCO performance terms

AMCO sums it up as repair, replace, or refund.

If new AMCO equipment does not perform as promised during the first 30 days, AMCO first works to make it perform.

If that does not happen in a reasonable amount of time, AMCO says it will repair it, replace it or buy it back.

Bearing warranties

Maintenance-free gang bearings carry a three-year warranty; Protect-O-Shield and ditcher bearings carry two years.

Bearing coverage

Disc gangs feature maintenance-free bearings with three-year warranty; bearings eliminate possibility of contamination and need for re-lubrication.

Protect-O-Shield Bearings eliminate blown seals and prevent wrap damage; backed by our exclusive two-year warranty.

Built in Yazoo City, Mississippi

AMCO has built its equipment in Yazoo City since 1963.

Options

AMCO lists these options and upgrades. Not every option fits every model, so ask us which ones fit the harrow or ditcher you want.
