I prefer to use a drop pole. A drop pole requires a neck yoke which is long enough to attach to the center of the collar, which ever kind collar is used. The yoke is thusly carried by the horses without pulling them sideways. The attachment points at the end of the yoke (to the collar), should be the same distance apart as the center of the single trees. This keeps the horses pulling in a straight line. If a fixed, or "supported" pole is used, I suppose a short yoke could be used in place of the crab. The attachment could then be the same as for a crab. Don Hayes Keep driving!

Roeder To: Pairs List Sent: Friday, February 03, 2006 4:23 PM Subject: [drivingpairs] tongues/yokes Usually when a pole has a tongue/yoke to attach the collars/breastcollars to,(as opposed to a crab) it only goes up to the off center 'D' ring. Does anyone drive with a tongue/yoke long enough to attach to the center 'D' ring? And....what difference does it make? For those of you who are as technical-term impaired as I, by tongue/yoke, I'm refering to that swivel 'thingy' at the end of the pole we attach the collars to. Not asking for traditional or proper. Just want to know if anyone uses one and why. Helen
