A couple of weeks ago, a neighbor brought his compact Kubota into the shop with a busted PTO shaft. He'd been in a hurry to start his spring tillage preparation and skipped a check that takes ten minutes. My grandfather taught me this trick — still works 40 years later: before the disc goes anywhere near the field, you lift the tractor off the ground and turn the PTO shaft by hand. If it grinds or catches, you just saved yourself a $400 replacement. That's what this whole routine is about — catching small failures before they turn into season-ending repairs.
I run a third-generation auto repair shop outside San Antonio and also keep a small ranch. I've learned that spring tillage preparation is half equipment and half soil. If either one is wrong, you're burning diesel and making dust.
Why Spring Tillage Preparation Starts in the Shop
Most folks think of spring tillage preparation as a field job: hook up the disc, drop it in the ground, make a few rounds. The real work happens before you burn a gallon of diesel. A tractor that sat all winter has seals that dried out, a battery that drained down, and hydraulic oil that may have picked up condensation. Failing to check those means breakdowns when the planting window is narrow. I'd rather do the work on a dry concrete floor than on my knees in wet Texas blackland.
Walk your machinery yard once before you start. Look for dropped pins, cracked hoses, and puddles of oil. It takes twenty minutes and saves a field call. If you're not sure, take it to a pro. No shame in that.
The Tractor Checklist: Five Checks That Pay for Themselves
Start with the PTO. Remove the shaft cover and grease every fitting. Look for rust on the splines and any play in the universal joints. A worn u-joint that runs fine at idle will start to vibrate at 540 RPM and can snap a shaft in seconds. Next, check the hydraulic system. On a Deere or Kubota, a small leak at a coupler can cost you two to five quarts of fluid by the end of the day. Fix the fitting now. A $30 part and an hour of labor beats a $600 pump failure.
Then check the engine oil and coolant, and don't forget the fuel filter. Diesel filters can clog after sitting; a $20 filter is cheap insurance against a weekend of frustration. Finally, inspect your tires and ballast. For a compact tractor with a loader, check the rear tire pressure before you hang a heavy tillage implement off the three-point. Underinflated tires make the tractor wobble at field speed, and overinflated tires create compaction that ruins your seedbed. Proper pressure for a 4000-pound tractor on a disc harrow often falls around 18 to 22 psi in the rears, but check the sidewall. Every model is different.
Shop Trick: rub a little grease on the PTO spline before you connect the implement. It keeps moisture out and makes the connection a hundred times easier to pull apart next season. My grandfather did that on every tractor he owned.
Soil Readiness: Don't Work Ground That's Not Ready
Your equipment is only half the job. The soil has to be ready too. Working ground that's too wet leaves compaction layers that last all season. Working ground that's too dry turns your seedbed to dust. A simple test: pick up a handful of soil from a few inches down and squeeze it into a ball. If it crumbles when you poke it, you're ready. If it stays a mud ball, wait a day or two.
Also think about what's growing on the field. If you're finishing a cover crop, spray or roll it at six to eight inches tall, then wait a week or two for the residue to break down. Some ranchers skip the disc entirely and use a no-till drill, but that's a different setup. For a conventional setup, make one pass with a chisel plow after a rain, then a second pass with a disc harrow set at four to six inches deep a few days later. That gives you a nice crumbly seedbed without grinding the life out of the soil.
A Budget-Conscious Spring Tillage Preparation Routine
You don't need to spend a fortune to get the most out of spring tillage preparation. A basic soil test runs fifteen to fifty dollars at your local ag extension office, and it tells you exactly what fertilizer to skip. That alone can save you a couple hundred dollars on inputs. On the equipment side, a tube of grease costs five dollars. A hydraulic fitting costs twenty. A roll of shop towels is eight. For less than a hundred bucks, you can cover the most common failure points before they cost you a hauling bill or a new part. Compare that to a broken PTO shaft at four hundred dollars plus the time you lose waiting for parts. The math isn't close.
I'll be honest: some years I'm the guy who wants to hook up and go. The older I get, the more I appreciate the slow morning in the shop. It's quiet, you have good coffee, and you know the tractor is going to run when you need it. Spring tillage preparation is really just respect for the work ahead. Do it once, the right way, and your season runs smoother for the whole year.
One More Thing Before You Head to the Field
Once your spring tillage preparation is done, take one lap around the field on foot. Look for standing water, tree branches, and fence wire that winter winds may have buried. Then go make your first pass. If something feels wrong, stop and check it. That's not being timid; that's being smart. My grandfather taught me that too.
