John Deere 437E and 337E Knuckleboom Loaders will now come with a new grapple. The product is available with a 48- or 52-inch opening, and it is designed to improve rotator torque and response times for loggers looking to keep up at their landing.
"If I could describe the new grapple in one word, it would be 'nimble' — and my operator agrees," said Donald Mixon, owner of Mixon Saw Mill in Bermuda, Alabama. "It's smoother, faster and holds wood well during second thinning. Overall, it just feels tough."
The grapple has a rotator lift capacity of 123,000 pounds, and rotator torque of 36,200 pounds per inch. It is composed of high impact custom steel, which means it is resistant to wear and tear over time. The grapple is designed to run better by being more integrated into the machine’s hydraulics.
The 437E and 337E Knuckleboom Loaders are designed to provide five percent more swing torque and lift force compared to previous models. Loggers will find that the new grapple complements these features of the loaders.
In addition, they are more optimized to run from a John Deere carrier. This is comparison to previous models, which used a grapple from a third-party.
