Getting started
The map won't centre on me, or I see a "no GPS" message
Tractor GPS needs location permission to guide you or record anything. Check iOS Settings → Privacy & Security → Location Services → Tractor GPS and set it to While Using the App or Always.
After that, give it a minute or two for the first satellite fix, and check the phone's view of the sky — cab roofs and coated windscreens both attenuate the signal.
How do I set up a field?
Open the Fields tab, tap + and place boundary points on the map with the crosshair, or create a field from a job you have already driven (Work Log → Create Field). The app shows the enclosed area in acres or hectares as soon as the boundary closes. Section 5 of the user guide walks through it.
How do I start guidance?
Set up an implement profile first (Implements tab — width and offset), then go to Drive, drop your A point at one end of a pass and your B point at the other. The app draws parallel passes from that line and paints coverage as you drive.
Accuracy
How accurate is it?
The iPhone's built-in GNSS updates roughly once a second and is typically accurate to a metre or two on newer dual-frequency iPhones and up to about 5 metres on older ones — fine for coverage mapping, spreading and general field work. For tighter passes, pair an external GNSS receiver in iOS Settings → Bluetooth; iOS then uses it in place of the phone's GPS, and accuracy depends on the receiver.
My position jumps around
Mount the phone in a fixed position — holding it or moving it about degrades the fix. If the jumping continues, an external receiver is the fix; see section 10 of the user guide.
The guideline is off, or my passes don't line up
Almost always one of three things:
- the active implement's width is wrong;
- the offset is wrong for a tool that isn't centred behind the tractor;
- A and B were set on a stretch that wasn't actually straight — re-set them.
Subscription
How does the trial work?
In the app, Tractor GPS offers a 7-day free trial, then an annual subscription. You'll get a reminder before the trial ends, and you can cancel any time from iOS Settings → your name → Subscriptions. If you bought on our website instead, see the Refund & Cancellation Policy.
I subscribed but the app doesn't recognise it
Tap Already Purchased? on the paywall screen, signed in with the same Apple ID you used to subscribe. If it still doesn't find it, email us and include the Apple ID email address you used.
How do I cancel?
Subscriptions bought in the app are billed by Apple, so they're cancelled in iOS Settings → your name → Subscriptions → Tractor GPS → Cancel Subscription. We can't cancel those for you, but we're happy to help if it's not working.
Bought on our website? Cancel at get.tractorgps.com/manage. The Refund & Cancellation Policy covers both.
Still stuck?
Email [email protected]. It helps enormously if you include:
- your iPhone model and iOS version;
- the app version (iOS Settings → Apps → Tractor GPS, or the App Store page);
- what you expected to happen and what happened instead.
You can also reach us from inside the app at Settings → Contact Support, which fills most of that in automatically.
