Serving Western Ohio's Large Ag Producers


With 29 years at Koenig Equipment and roots on the livestock farms he grew up working, Jeff Holthaus helps large ag producers across western Ohio get the most out of their John Deere equipment. His sweet spot is tillage, seeding, and harvesting — and he's just as comfortable in the field as he is at the desk.


Jeff Holthaus

Customer Account Manager

A Fort Loramie native, Jeff grew up working on a couple of livestock farms — the start of a lifetime in agriculture. What he enjoys most about the job is simple: actually helping his customers.

Away from work, Jeff is happily married to Lisa and keeps busy chasing around their five kids. When time permits, he enjoys hunting and fishing.

Who Jeff Works With

Jeff works primarily with large ag producers across a nine- to ten-county area in western Ohio, tailoring every recommendation to the acres, the operation, and the results a customer is after.

  • Customers looking to add capacity and efficiency to their fleet

Customer-First Approach

Jeff's approach starts with one thing: he tries very hard to listen. By understanding what a customer is actually trying to accomplish, he can match the right equipment and setup to the job — and then back it up with real support in the field.


One of his most common pieces of advice:
“Let's do what the operator's manual says first — then, if we have to, we can get creative.”

In the Field

Jeff's edge is hands-on experience. Through years of field starts, he's been on the front line making the adjustments that get equipment dialed in — setting margins correctly on a planter, or cleaning up the sample on a combine. When a machine needs to perform, Jeff makes sure it does.


  • 29 years of experience across tillage, seeding, and harvesting equipment
  • In-field setup and field starts to get machines running right
  • Practical, honest guidance grounded in real operating experience

“My favorite part is the smile when things are working the way they're supposed to.”
