How to Effectively Use a Potato Harvester

Potato harvest season moves fast. When your crop is ready, the last thing you want to do is figure out your equipment while potatoes are still sitting in the ground.

Getting your potato harvester set up ahead of time can make harvest day a whole lot easier. Here’s how to get started.

Make Sure Your Tractor Is Ready

Before attaching anything, check that your tractor is compatible with your harvester.

The MechMaxx PH19 Potato Harvester is designed for tractors with 20–30 HP, uses a Category I 3-point hitch, and operates at 540 PTO RPM. It's also compatible with Cat-1 quick hitches.

Taking a few minutes to confirm compatibility now can save a much bigger headache later.

Attach and Inspect the Harvester

Secure the harvester to your tractor’s 3-point hitch and connect the PTO according to the operator’s manual. Before starting, inspect the blade, linkage, PTO shaft, fasteners, and other moving components.

The PH19 includes a PTO shaft with a 6-spline quick-release tractor yoke, plus a replaceable blade and linkage for easier maintenance.

And, as always, shut the tractor down completely before making adjustments or working around the PTO.

Set Your Digging Depth and Angle

This is where a little trial and error can pay off.

The PH19 lets you adjust the digging depth and angle so the blade can travel underneath the potatoes rather than straight through them.

Start conservatively and test a short section of your row. If you’re leaving potatoes behind, you may need to go deeper. If you’re cutting into them, adjust your setup before continuing.

A five-minute test run beats a field full of sliced potatoes.

Line Up With Your Rows

Once everything looks good, line the harvester up with the center of your potato row and begin moving forward at a controlled pace.

The PH19 has a 19-inch working width and is designed to dig a single row at a time. As it moves, the machine lifts the crop, separates much of the soil, and deposits the potatoes back onto the surface for collection.

From there, the hardest part is picking them up.

Keep an Eye on Your Results

Soil conditions, crop depth, row spacing, and tractor speed can all affect your harvest.

Check your first few passes before tackling the whole field. You want potatoes coming out cleanly with minimal cuts, bruising, or crops left behind.

Once you find the setup that works for your field, stick with it and keep moving.

Ready for Harvest?

A little preparation before harvest day goes a long way. Get your tractor ready, inspect your equipment, dial in your digging depth, and test your setup before the big day.

Then let the potato harvester handle the dirty work.

Because harvest season is busy enough already.
