John Deere 8345RT

Last Updated: July 2024

Overview

The John Deere 8345RT is an agricultural crawler tractor featuring a robust 6-cylinder, 9.0L John Deere PowerTech PSS engine with two turbochargers and Tier 4B emissions compliance achieved through DOC, SCR, and regenerative DPF exhaust treatment. The liquid-cooled engine delivers a maximum power output of 329.11 hp at 1750 rpm, with a rated speed of 2100 rpm. Cooling is managed by a thermostat and variable-speed fan. The infinitely variable transmission (IVT) offers smooth control with nominal travel speeds of 0-26.1 mph forward and 0-11.8 mph reverse. An electro-hydraulic power steering system and 4x4 MFWD 4WD configuration ensure optimal traction and maneuverability. The hydraulic system is closed-center pressure-flow compensated, with a maximum flow rate of 61.5 GPM at rated engine speed. The tractor has substantial dimensions and an operating weight of 34,360 lbs, enabling it to handle demanding agricultural tasks. Detailed performance data is available, including drawbar power, fuel consumption, and slip percentages under various load conditions. The exhaust system utilizes a 32% aqueous urea solution (DEF) for emissions treatment. Sound levels are measured at 86.5 dB(A) for bystanders.
