How it works
1. Tell us about your tractor Fill in the order form — make, model, year, and a couple of photos of your steering column with the wheel removed. Takes ten minutes.
2. We match your kit We confirm the correct motor adapter for your steering shaft and quote you a fixed price and lead time.
3. You pay, we build Once you’ve paid, we source and assemble your kit — every unit is built and bench-tested before it ships. Nothing sits on a shelf waiting for a buyer, so you’re getting parts built for your tractor, not picked from old stock.
4. Fit it yourself Your kit arrives with every cable labelled, a step-by-step guide, and video walkthroughs. Most farmers have it running in a few hours with basic hand tools.

Important: what this kit does and doesn’t do
This is a steering guidance kit only — it keeps your tractor tracking a straight line so you’re not fighting the wheel all day. It does not control implements, spray sections, or variable-rate spreading. If you’re after variable-rate fertilizer or lime application, that’s a separate system entirely — ask us and we’ll point you in the right direction.
This kit is built for tractors with a mechanical/hydrostatic (orbitrol) steering column — the kind where the wheel bolts onto a splined shaft under the covers. If your tractor already has a factory “steer-ready” electronic steering system, this kit isn’t the right fit for you — talk to your dealer about their integrated option instead.
Pricing
Every kit is quoted individually because it’s built to your tractor, not pulled from stock. As a guide, complete kits typically land in the R50,000–R75,000 range depending on tractor model and tablet choice — get an exact quote in under a day once we have your details.
FAQ
Will this fit my tractor? If your tractor has a normal mechanical or hydrostatic steering column — the wheel bolts onto a shaft, and there’s no factory “auto-steer ready” electronics already built in — almost certainly yes. We match the motor’s adapter to your exact shaft, confirmed from your photos before we order anything.
How accurate is it? With the RTK GPS option and a cellular correction signal, guidance accuracy is around 2.5cm — tight enough for planting and spraying, not just rough guidance lines.
Do I need cell signal in my fields? For full RTK accuracy, yes — the system needs a correction signal over a data connection. If your fields have poor signal, tell us on the order form and we’ll discuss a base station option instead.
Can I still steer manually? Yes, at any time. Grab the wheel firmly and the system disengages automatically — it’s a safety feature, not something you switch off in a menu first.
What if my tractor details on the form aren’t exact? That’s why we ask for photos and a shaft measurement before we order parts — we’re not building from a make/model guess alone, so mismatches are rare. If something doesn’t fit on arrival, contact us before attempting to force anything.
Is this covered by warranty? See the terms on the order page — installation and use are the owner’s responsibility once the kit leaves us.
Do you offer variable-rate spreading or spray section control? No — this kit is steering guidance only. That’s a separate system built around your specific spreader or sprayer; get in touch and we’ll point you toward the right setup.
