Jacks for Sale

Please send your phone number when e-mailing us with serious inquiries.

We have a number of very nice jacks for sale. If you are looking for a well bred jack for your breeding herd, please contact us. Tell us what your needs are! We are sure we will have just the right jack to add to your breeding program. We strive for quality!


Having been in the jack and jenny business for a half century. I find one common fact that we have dealt with for each and every one of these 50 years. The fact is funny in a way and very understandable in another way. Here it is! 99% of people don't want a jack on the place until 15 minutes before their mare comes in heat.

Every year in mid to late summer we purchase some very nice jacks that will breed mares. People have their mares bred and are ready to sell these jacks with no regard
for the fact that next spring they once again will not have a jack to breed them to!

On the other end of this situation we purchase the jacks and offer these jacks for sale to our customers at reduced prices until January and February of the next year. After that time we will sell them for full price. This past 2017 spring we received 22 calls between February 15th and April 15th looking for a jack that breeds mares. (Some were almost desperate)

Point: The time to buy a mare jack is when you find one that suits you and NOT at the last minute. Once again this process has started! We are offering at this time two VERY nice jacks at summer sale prices that will solve your mule baby problems this coming spring.

It will be interesting to see if history repeats itself once again or people finally learn their lessons. Either way we are prepared. What about you?


Ace is a 60 inch 11 year
old heavy boned black jack that breeds jennies.

Bulldog 2017 Jack

Bulldog is a 6 year old sorrel jack that is 54 inches tall. Bulldog will absolutely breed mares! He is thick built and fairly heavy boned. He has enough body and bone to be a 15 hand jack, just as his pictures show. He has great confirmation and excellent feet. He is easy to handle and a pleasure to have around.


Checotah is a 14 year old black jack that is 57 inches tall. Checotah is from the Jack Seiman farm in Indiana and one of the few left from that blood line. He only breeds jenny's but is a real opportunity to add this bloodline to your herd. He will be a real bargain for someone looking for a jenny jack.

Cheotah 2017 Jack

Romeo 2017 Jack ROMEO

Romeo is a 6 year old dark gray dun jack that is 57 inches tall. He will breed mares in hand or in the pasture. Romeo is full bodied, has a great hip, deep in the chest and wide between the front legs. His legs are straight, he has good feet, and he is medium boned. This jack can solve your breeding problems. He can end the crazy fees and vet bills associated with shipping semen as well as the inconvenience and expensive travel costs associated with transporting your mares to and from the closest mare jack.



Tucker is a 20 month old sorrel jack colt measuring 58 inches tall and growing like a weed. He should be ready to start breeding by the spring breeding season. His disposition is great, his legs are straight, his feet are excellent, and his teeth match. Tucker is headed for a 15 hand or bigger jack. We rarely have a jack this age and size for sale.
