Harness & Yoke Making

A draft animal without proper harness is wasted potential. A poorly fitting harness is worse — it injures the animal, reduces pulling power, and eventually makes the animal refuse to work. Good harness-making is one of the most valuable skills in a recovery community.

This article covers three main systems: the collar harness (horses and mules), the breast harness (lighter work), and the ox yoke (cattle).

Collar Harness

The collar harness is the most efficient way to use a horse’s or mule’s power. It distributes pulling force across the shoulders and chest, allowing the animal to lean into the work with its full body weight.

Building the Collar

A horse collar is an oval padded frame that sits around the animal’s neck and rests on the shoulders.

Materials:

  • Two curved pieces of hardwood (or laminated strips) forming the collar frame
  • Heavy leather or canvas for the outer shell
  • Stuffing: straw, wool, cattail fluff, or salvaged foam
  • Inner lining: smooth leather or canvas to prevent rubbing

Construction steps:

  1. Measure the animal. With the horse standing square, measure:
    • Width of the neck at the base, just above the shoulders
    • Height from the point of shoulder to the top of the neck
    • Depth of the chest at the shoulder point
  2. Shape the frame. Steam-bend or laminate two curved arms from ash, oak, or hickory. The opening should match your measurements with 2-3 cm clearance all around. The collar must be wide enough to slip over the head, then rotate 180° to sit in working position.
  3. Pad the frame. Build up stuffing on the inner face of the collar, thickest at the sides where the shoulders bear the load. The padding should create a smooth, even bearing surface with no lumps or thin spots.
  4. Cover with leather or canvas. Stitch the covering tight. The inner face (against the horse) must be very smooth — any wrinkle or seam ridge will cause a sore within hours of work.
  5. Shape to the individual animal. Work the collar against the horse’s shoulders, pressing and adjusting the stuffing until the pressure distributes evenly. No two horses have identical shoulders.

Hames & Traces

Hames are two curved pieces (wood or metal) that clamp to the outside of the collar. Traces (long straps or chains) attach to the hames and run back to the load.

  • Wooden hames: Carved from a naturally curved branch or steam-bent. Must follow the collar’s curve exactly.
  • Metal hames: Salvaged from farm equipment, or forged by a blacksmith. Steel hames are stronger and last longer.
  • Traces: Heavy leather straps, chain, or strong rope. Length depends on whether you’re pulling a cart (short, attach to shafts) or a plow/log (long, 2-3 m).

The hame straps hold the hames tight to the collar at top and bottom. If the hames shift, pulling force concentrates on a small area and creates sores.

Fitting & Adjustment

A collar fits correctly when:

  • You can slide your flat hand between the collar and the horse’s neck at the sides
  • The collar sits firmly on the shoulders without rocking
  • The bottom of the collar clears the windpipe — there is zero pressure on the throat
  • The top of the collar sits below the crest of the neck

Seasonal refitting: Horses change shape with condition. A horse that fattens over summer on good pasture needs the collar adjusted. A horse that thins over a hard winter needs padding added. Check fit weekly.

Breast Harness

The breast harness is simpler to make but less efficient for heavy pulling. It works well for light carts, riding horses doing occasional hauling, and mules.

Breast Strap Design

The pulling force transfers through a wide strap across the chest.

  • Width: Minimum 8 cm, ideally 10-12 cm. Narrow straps concentrate pressure.
  • Padding: Line with sheepskin, felt, or folded cloth.
  • Position: The strap sits across the point of the shoulder, NOT on the windpipe. Too high chokes the horse. Too low interferes with the leg motion.
  • Traces attach at each end of the breast strap, running back to the load.

Limitations: A breast harness transmits force through a relatively small area. For loads over 150-200 kg on flat ground, switch to a collar harness or the animal will develop chest sores.

Surcingle & Belly Band

When using a breast harness with a two-wheel cart:

  • A surcingle (girth strap) passes over the back and under the belly, holding the shafts at the correct height
  • A belly band passes under the belly and connects to the shafts, preventing them from tipping up when the cart pushes forward on downhills
  • A back strap runs from the surcingle to the breeching (a strap around the hindquarters) for braking and backing

Without the belly band, going downhill becomes dangerous — the shafts can fly up and strike the animal.

Ox Yoke Construction

Oxen (trained cattle) pull from the neck and shoulders using a yoke — a shaped wooden beam that sits across two animals.

Neck Yoke Design

The neck yoke is the standard in North American and Northern European tradition.

Materials:

  • One piece of hardwood: 120-140 cm long, 10-15 cm wide, 8-10 cm thick. Elm is traditional — it resists splitting.
  • Two U-shaped bows: steam-bent hardwood or forked branches, about 50-60 cm around
  • Lashing or iron staples to secure bows

Construction:

  1. Shape the beam. The yoke beam is slightly curved to sit on the animals’ necks. Carve two shallow saddles where the necks sit, spaced about 90-100 cm apart (center to center).
  2. Drill bow holes. Below each saddle, drill two holes for the bow ends to pass through. The bow wraps under the ox’s neck and both ends come up through the beam.
  3. Fit the bows. Each bow should fit snugly around the ox’s neck with about 5 cm clearance all around. Too tight restricts breathing. Too loose lets the yoke shift and causes rubbing.
  4. Secure bow ends. Above the beam, the bow ends are pinned with hardwood keys or wedged. They must be removable for yoking and unyoking.
  5. Attach the ring or chain. A ring or chain at the center bottom of the yoke connects to the load (cart tongue, plow chain, or drag chain).

Head Yoke (Horn Yoke)

In Mediterranean and parts of Asian tradition, the yoke attaches to the horns rather than the neck. This works only with horned cattle.

  • The beam sits behind the horns and is lashed to them
  • Pulling force transfers through the skull — cattle are remarkably strong this way
  • Not suitable for dehorned or polled breeds
  • Requires different training than neck-yoke work

Yoke Fitting & Padding

  • The neck saddles should be carved to match the animals’ neck shape — spend time fitting
  • Line the saddles with sheepskin or thick felt to prevent rubbing
  • Both animals in a pair should be similar in size. A badly matched pair means one animal does most of the work and the yoke sits crooked
  • Check for sores daily. Any redness or hair loss means the fit is wrong

Materials & Improvisation

Leather Alternatives

If leather is scarce, workable alternatives include:

  • Seatbelt webbing: Incredibly strong, already the right width for straps. Salvage from any vehicle.
  • Nylon rope: Can be braided into flat straps. Cover with cloth padding where it contacts the animal.
  • Canvas: Multiple layers stitched together. Not as durable as leather but functional.
  • Fire hose: Flat-weave fire hose is extremely strong and already flat. Excellent for traces and breast straps.
  • Paracord: The inner strands woven or braided make decent light lines. Not strong enough for traces alone.

Padding & Cushioning

Padding prevents every type of harness injury:

  • Wool or sheepskin: The gold standard. Naturally wicks moisture and stays cushioned.
  • Felt: Dense wool felt is traditional collar stuffing.
  • Straw: Works but compresses and must be replaced frequently.
  • Salvaged foam: Closed-cell foam from seat cushions, sleeping pads, or vehicle seats. Cut to shape and cover with cloth to prevent crumbling.
  • Cattail or milkweed fluff: Lightweight and compressible. Needs a fabric shell.

Preventing Harness Injuries

Common Harness Injuries

  • Collar sores: Raw or open skin on the shoulders, caused by poor fit or dirty collar lining. The number one harness problem.
  • Girth galls: Sores under the belly band or surcingle, caused by friction, sweat, and grit.
  • Wither rubs: Sores on top of the neck at the withers, from a collar or saddle sitting too high.
  • Windpipe pressure: A breast strap or collar too low compresses the trachea. The horse coughs, struggles to breathe, and may panic.
  • Trace rubs: The traces rub against the flanks or hips if they’re not routed correctly.

Treatment & Rest Protocols

If a harness sore develops:

  1. Stop working the animal immediately. Continuing work on a sore turns a minor problem into a major one — deep sores can take weeks to heal.
  2. Clean the wound with clean water. Remove any crusty material gently.
  3. Apply a barrier. Pine tar, clean oil, or antibacterial ointment if available.
  4. Rest the animal until the sore is fully healed and new hair is growing. This may take 5-14 days for a minor sore.
  5. Fix the harness before returning to work. The sore happened for a reason — identify and correct it.

Prevention is everything:

  • Clean the collar lining or breast strap daily. Dried sweat and grit are abrasive.
  • Check the animal’s skin before and after every work session.
  • Build up work gradually — don’t go from zero to full days of heavy pulling.
  • Keep the animal well-fed. Thin animals with prominent bones are more vulnerable to pressure sores.
  • Ensure the harness fits. If the animal changes condition, adjust the harness.
