2024 John Deere 4 Series 4066M

2024 John Deere 4 Series 4066M

• Turbocharged diesel engine

• PowrReverser™ or eHydrostatic Transmission options

• Standard 4-wheel-drive

• Category 1, 3-point hitch compatible with iMatch™ Quick-Hitch

Features may include:

The bold styling of the 4M and 4R Tractors provide an attractive and functional appearance similar to that of the larger agricultural tractors. Benefits of this styling include:

• Easy tractor family identification

• Updated fixed grille and side panel hood design allows for optimum sealing of the cooling compartment

• Front grille slides up to an integrated maintenance position for easy battery access

• Easily removable cowl, allowing for serviceability access

• Wraparound-style halogen headlights

• Premium integrated automotive style headlight bezels

• Bold graphics

• Aggressively sloped hood design, giving a softer, smoother look and providing improved visibility

• Hybrid exhaust in base on cab tractors for clear operator visibility and safety

• At low speed and when tractor is in a filter cleaning process, exhaust will be routed through vertical exhaust outlet. In all other cases, the exhaust will be routed through the downward exhaust outlet.

• Side exhaust in base on open operator station tractors and ensures minimal heat impact to operator

The result gives the tractor a distinctive appearance and feel.

The Yanmar diesel engine has a high-torque reserve that provides plenty of power under heavy load.

This 4-cylinder engine features lower levels of exhaust emissions and reduced noise levels. It meets EPA Final Tier 4 (FT4) emission standards.

Engine hp (kW), gross SAE J1995: 65.9 (48.5) at 2600 rpm, PS

Displacement, cu in. (L):128.15 (2.1)

The engine uses the latest technologies to optimize fuel economy, improve control and accuracy, and reduce environmental impact.

The common rail system (CRS) optimizes fuel economy and reduces operating costs. High-pressure injection atomizes fuel into finer particles which burn more completely. It results in improved fuel economy and lower cost of operation.

The electronic control unit (ECU) provides optimum fuel control and accuracy. ECU monitors and controls the engine. It continuously monitors engine conditions and adjusts the fuel delivery accordingly to ensure optimum performance and emissions.

The new engine comes with an after treatment system. The system operates automatically. The exhaust filter consists of a diesel particulate filter (DPF) which captures particulate matter (PM) contained in the exhaust gas. Using a natural cleaning process, most of the PM trapped in the exhaust filter is eliminated by the heat of the exhaust stream generated by normal use. In situations of low temperature, engine speed or load factor, an active cleaning cycle is initiated. In this cleaning cycle, the exhaust gas temperature is raised by injecting additional fuel during the exhaust stroke of normal vehicle operation to the diesel oxidation catalyst (DOC).

After many hours of use, the exhaust filter may require an ash removal service.

As compared to engines not using CRS technology.

• Depending on the load that the tractor is under, as well as ambient temperature, humidity, and engine speed, the DPF may build up with particulate matter, thus requiring cleaning. Filter cleaning is determined by one of three conditions:

• A prescribed time-based estimation of needed filter cleaning

• DOC/DPF pressure sensors
