There are many different driving bits with many subtle variations and strange names. While there seem to be new types of riding horse bits being created all the time, driving horse bits tend to be more traditional. Here are some of the most common driving bits you'll see. Here is a brief overview of each bit. Clicking on the title of the bit will take you to more details.
The Liverpool Bit is probably the most common driving bit. It's used on every type of hitch from light one horse rigs to draft horses at pulling competitions.
This vintage full cheek snaffle has ornate cheek pieces to go with a formal harness and rig. The large cheek pieces will prevent the bit pulling through the horse's mouth and from hooking into the harness.
The straight bar snaffle is a bit you will often find lying rusty in dusty boxes at a farm auction. Back when horses were the main power of the family farm, these bits were popular. While no longer as popular, as more comfortable and effective bits have become available, the straight bar snaffle is still used occasionally although most horses will find them an uncomfortable mouthful.
