We appreciate that you have considered our auction in your search in finding a MULE that will fit your needs and requirements.  We encourage you to take the time to inspect, screen and ask questions about the mules that peak your interest.  It is the Buyers responsibility to ride AND talked with the consignor about the animal prior to purchase.

OUR SUGGESTION:  If you are wanting a trail mule that is safe and sane, please consider as a scenario you are buying a Pickup or an ATV versus a race car, even though the race car is sleek and certainly has that cool look, you may be better off with something that has the versatility and undercarriage you may need.  The old saying, "The beauty queen doesn't always make the best cook", could apply as well.  Please choose disposition, riding requirements, personality and temperament.  Make sure that if a Mule has reining training that you are able to ride the animal that can spin on a coin, move from walk to run in one jump, and you can sit back when you ask the mule to slide to a stop.  Buy a Mule that fits your riding ability!

THIS IS NOT A BUY, THEN TRY AUCTION!  This is totally unfair to the consignors and their business of selling reliable animals!

We pride ourselves on working with the consignors in our sale as they have proven to bring the type of mules that are safe and sound and that our buyers need and deserve.  We list the number of year’s each consignor has been with us, thus verifying their proven history of sales they’ve had with our Auction.  Please know what these consignors have sold their mules for in the past by reviewing the "Historical Prices" and what they may expect their animals to bring in this year's auction. 

 If you wish to obtain a PRE-PURCHASE Vet Inspection, it must be done prior to the Auction at the potential buyers expense. Mules are stalled at Jake Clark's MULE DAYS Arena & Barn and a buyer should contact any consignor to make arrangements for a Prepurchase-vet check for a specified mule at this location, in Cody, Powell or at the consignor’s location through a vet near them.

We do not guarantee a buyers Prepurchase-vet inspection, we guarantee that the mules will be sound per our "Soundness Guarantee" listed below in the Guarantee Section of this page.

ABSOLUTELY "NO" Private Sales

Absolutely NO Private Sales:  with any of Jake Clark's MULE DAYS consignor's either prior to the Sale or after the auction. Consignors have given Clark Management Company Exclusive Rights for selling the consigned Mule(s).  Management feels this is unfair to the consignors and buyers who have traveled to attend the sale. All mules brought to the sale to be sold during Jake Clark's MULE DAYS must be consigned and go through our auction ring. The GUARANTEES only apply if the sale is run through the AUCTION.  To insure all sale GUARANTEES go with each mules purchase, be sure to come to the office to let us know you have made arrangements to purchase one of the mules that did not sell in the Ring.

After the Sale, we continue to try to sell the mules and will post them to Facebook and other area's to let potential buyers know what mules are still available.  We do leave it up to the integrity of the seller to forward any commission on mules that have been consigned to this sale, have their mules listed in the catalog, and/or are sold because of the advertising and efforts of the Jake Clark's MULE DAYS.  We work hard to do right for both our buyers and our consignors and want to thank those consignors and buyers that possess the integrity to know that we have done a great job and will pay us accordingly to their contract.
