Overview
The SyncShuttle transmission is designed to match the excellent power and torque characteristics of the John Deere PowerTech™ engines. The 9F/3R SyncShuttle provides nine forward and three reverse speeds with in-line synchronized shuttle shifting.
Benefits
- Transmission durability is enhanced with the pressure-lubricated top shaft, allowing the operator to achieve performance from one working season to the next
- Easy and comfortable shifting
- Operator-friendly transmission controls with hand throttle
Additional detail
Additionally, the in-base transmission is configured with fixed draft links, single-speed power take-off (PTO) and mechanical PTO engagement.
The transmission is characterized as full top shaft synchronized (TSS) when forward shifting on-the-go between speeds and is characterized a synchronized while depressing the clutch.

Easy and comfortable shifting
Operator-friendly transmission controls with hand throttle
Synchronized shifting in all forward and reverse gears
Range selection pattern
Nine forward and three reverse (9F/3R) speeds are achieved by using two platform-mounted levers for shift operation. The gear lever at the operator's right hand selects one of three forward gears and one reverse gear, as well as the integrated park position. The range lever at the operator's left hand selects collar-shift A, B, and C ranges.
Operators can easily switch directions without having to completely stop the tractor with synchronized, in-line, shuttle-shift capability between forward and reverse gears on the gear-shift lever in all three ranges (A, B, and C ranges).
A neutral start switch requires the gear-shift lever be in the neutral or park positions to start the engine.
A positive park pawl on the transmission provides positive park and eliminates the need for a hand brake. This also eliminates clutch service costs that occur when the park brake is accidentally left engaged.
