Pair draft animals that match in size and pace, because two animals of different speeds fight each other, and put the experienced animal on the off (right) side with the green animal on the near (left) side so the new one takes its cues from its partner. Oxen should be raised together if possible, since they form strong pair bonds.
Part of Draft Animal Training
Pairing two draft animals: matching, placing, and the load-sharing mechanics of the bar between them.
A Team Is Only As Good As Its Slower Member
Two animals of different speeds do not average; each pulls toward its own pace and the pair loses time and tempers. Size matters the same way: a smaller animal is overworked next to a larger one, and a yoke or pole sits crooked.
What You Need
- Two individually trained animals — each solid on ground work and drag loads.
- A matched pair — similar size and pace.
- An experienced animal — for the off side.
- A pole, yoke or bar — see Ox Yoke Construction for oxen.
Method: Pair Them
Step 1: Match size and pace. Walk them side by side loose in a pen to see which leads. A mismatch shows at once.
Step 2: Place them. The experienced animal goes on the off (right) side, the green one on the near (left) side.
Step 3: Drive on lines or alongside. Horses are driven from behind on lines; oxen, from beside the team. See Long-Line Driving.
Step 4: Start with empty or light loads. As with a single animal, a team starts with drags before a cart.
Step 5: Watch the sweat and the sores. If one animal sweats or tires first, it is doing more of the work. Check the yoke or collars for uneven rubs.
Worked Example
Pace mismatch: suppose one animal of the team prefers 5 km/h and the other 6 km/h, both within the carrier’s horse range of 5-6 km/h.
- Difference: 6 - 5 = 1 km/h = 1,000 m / 3,600 s = 0.278 m/s.
- In 10 minutes (600 s): 0.278 x 600 = 167 m.
Free, the faster animal would be 167 m ahead after 10 minutes. In harness it cannot get ahead, so the 167 m is converted into a steady lean on its partner. Mixed species are worse: a horse at 5-6 km/h beside an ox at 2-3 km/h differs by at least 2 km/h (5 - 3) and up to 4 km/h (6 - 2), which is 2 x 167 = 333 m to 4 x 167 = 667 m in the same 10 minutes.
Load sharing through a bar (a general mechanical point, not from the source article): with the bar pivoted at a point on the load, the pulls satisfy force x arm for each animal being equal. With equal arms, both animals pull equal force whatever their size. To make the stronger animal take more, give it the shorter arm: if arms are 40 cm and 60 cm, the animal on the 40 cm arm pulls 60 / 40 = 1.5 times the force of the other.
Common Mistakes
- Pairing a horse with an ox — pace and feeding both differ.
- Using equal arms for unequal animals — the weaker animal pulls as hard as the stronger one.
- Splitting oxen raised together — they form strong pair bonds.
Safety
One bolting animal takes the other and the vehicle
The pair is joined by pole or yoke, so a panic spreads. Rig a quick release for each animal’s trace and for the yoke, and rehearse it. Never stand between the animals or between either and the vehicle, and never hold lines wrapped around a hand.
