John Deere 8400r Apr 2026

Under heavy loads, the 675-liter fuel tank may limit daily output, as the tractor can consume roughly 75 liters per hour, potentially requiring a refill before a full day's work is completed.

The 8400R is exclusively fitted with the e23 full power shift transmission , offering 23 forward and 11 reverse speeds. This mechanical gearbox is noted for being perfectly suited to heavy cultivation.

It features a 9.0L PowerTech PSS engine delivering a rated 400 hp , capable of boosting up to 450 hp with Intelligent Power Management (IPM). It sets high standards for power efficiency, with independent tests showing it transmits roughly 91% of its power directly to the drawbar.
