John Deere 337E Knuckleboom Loader

The wiring harnesses of the electronic controller-based electrical system have been simplified to reduce the number of fuses, relays, and wires by approximately 30 percent compared to previous models.

Your John Deere Forestry machine arrives from the factory equipped with a powerful set of technologies and capabilities already built in:

• JDLink™ connectivity lets you track your equipment, see which machines are working, and know if they’re being utilized properly and at maximum productivity and efficiency.
• Enabled through JDLink, John Deere Connected Support leverages a suite of dealer and factory tools designed to deliver increased uptime and productivity, and lower daily operating costs.
• Remote Diagnostics and Programming Capability within John Deere Connected Support helps your dealer warn you of any issue with your machine — often before you know of the problem yourself — and initiate solutions without charging you for a technician’s visit to your jobsite.
• Our advanced dual approach to Machine Health combines the expertise of the technology specialists at our dealerships with the data specialists at our central Machine Health Monitoring Center (MHMC).

Redesigned cab-window guarding minimizes external barriers to expand visibility to the front while a lower left-rear hood profile opens up the view behind the machine.

Take the guesswork out of planning, implementing, and monitoring your logging operation. The tools of our production-planning and -tracking system expand on the core technology features that come standard in every John Deere Forestry machine to unleash a powerful new array of possibilities:

• TimberMatic™ Maps is an innovative onboard software solution that helps you reimagine your jobsites. Real-time production views, optimized routes, and shared wireless connections between machines make it easier than ever before to take your forestry operation to the next level.
• TimberManager™ is a web-based solution for PCs, tablets, and mobile phones that allows you to follow jobsite progress. Combined with TimberMatic Maps, this software provides complete visibility of your operation — from land harvested to specific machines — so you can streamline communication, analyze tasks, and increase productivity.

Rear and left rear windows have been replaced with heat-deflecting sheet metal that keeps the sun’s rays from scorching your back and neck while cooling the cab. Enhanced HVAC system stabilizes cab interior temperatures.

The 337E can be factory equipped with the optional John Deere 48-inch log grapple constructed of durable cast steel. Ample opening width ranging from 4 to 48 inches enables faster delimbing and loading of trucks.
