FEATURES
To stay ahead of the competition, you need to keep up at the landing. With powerful swing torque and lift force, streamlined hydraulics, reliable fluid economy, expansive visibility, and rugged components, the John Deere 337E Knuckleboom Loader is designed to withstand and take command of the most punishing logging environments. This proven performer sets the pace in the forest and in its class day after day.

EXPANSIVE VISIBLITY
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.

EFFICIENT SWING SYSTEM
Dedicated swing circuit provides the continuous power needed for productive delimbing and loading.

PRICISE CONTROL With a rotator designed for harsh pull-through delimbing applications, the Deere 52-inch grapple confidently grabs, lifts, and handles long, heavier trees. Vehicle hydraulics are tuned to match the grapple to enable precise operator control.

SIMPLIFIED ELECTRICAL SYSTEM
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.

PRICISION FORESTRY
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.

ITS EASY TO SEE
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. LED lighting options, including two lights on the machine upper frame, help illuminate delimbing tasks. * External front-window guarding removal meets operator-protection requirements.

MAKING THE CUT
Hydraulic options allow you to power a circle saw or self-propelled carrier, helping maximize uptime and productivity. Dedicated circle-saw pump increases cutting power and saw-recovery time, and it supports the requirements of all circle-saw sizes and applications.

FILLING THE VACUUM
Conveniently located inside the cab, an optional battery-operated vacuum pump helps avoid oil leakage from hydraulic components and reduces maintenance waste.

FILTER IT OUT
A second hydraulic oil filter doubles change intervals to 2,000 hours. Inline diesel exhaust fluid (DEF) filter boosts system reliability and serviceability.

IN THE SWING OF THINGS
Dedicated swing circuit provides the continuous power needed for productive delimbing and loading.
SIMPLIFIED ELECTRICAL SYSTEM
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. Diagnostic codes via the onboard display through JDLink ease fault detection.


TAKE CONTROL
With a rotator designed for harsh pull-through delimbing applications, the Deere 52-inch grapple confidently grabs, lifts, and handles long, heavier trees. Vehicle hydraulics are tuned to match the grapple to enable precise operator control.

FLUID DYNAMICS
John Deere EPA Final Tier 4 (FT4) engine maintains maximum engine performance while minimizing total fluid consumption diesel fuel plus diesel exhaust fluid. Operating rpm has been optimized to improve fuel efficiency by more than five percent, on average, without loss of machine performance.

COOL AND COMFORTABLE
Rear and left rear windows have been replaced with heat-deflecting sheet metal that keeps the suns rays from scorching your back and neck while cooling the cab. Enhanced HVAC system stabilizes cab interior temperatures. Satellite-ready radio option can be activated to expand cab amenities.
