Overview

Manufacturer

FordReference

Four power shift gears arranged in two synchronized ratio groups (1-4 and 5-8). Two synchronized ranges (low/high) and right-hand shuttle. Clutch must be used to shift range or move between the lower (1-4) and higher (5-8) gear ratio groups. Push-button power shifting between the four gears in a ratio group. Push-button de-clutching on the shuttle lever allow shifting without the foot clutch. The 16 power shift was standard on the 5640 SLE.Reference

Four gears, plus reverse, in two ranges. Tractor must be stopped, and clutch used, before shifting gear or range.Reference
