What is out there, and what to check before you buy.
There are three common ways to run a tractor's PTO and throttle from outside the cab. We make one of them, so weigh this with that in mind.
| Shop-built linkage | Armrest actuator kit | Plug-in harness (PowerSync) | |
|---|---|---|---|
| How it works | Rods or cables to the levers | Motors press the tractor's own controls | Sits between the sensors and the tractor's computer |
| Cab changes | Often drilling or brackets | Hardware mounted on the armrest | Inline connectors, no splicing |
| Reach | Length of the linkage | Wireless | Wireless, up to about 300 ft in the open |
| Fits | Whatever you build it for | Depends on the kit | John Deere models with a matching harness |
