Jacobsen’s all-new LF557/LF577 seven-reel mowers are the industry’s only Tier 4 final, seven-reel mowers, according to the company. The LF557 is equipped with five-inch reels, and the LF577 is equipped with seven-inch reels, with both mowers boasting a cutting width of 139 inches, allowing the ability to mow up to 11 acres per hour.
The seven-reel models feature technology that makes operation and service easier. A new AdaptiThrottle automatically manages engine speed based on demand, thus reducing fuel consumption and noise. The mowers’ InCommand Control System delivers pass code-protected, programmable max transport and mow speed settings to control cut frequency, removing tools and operator input from the equation. A new nine-bladed reel is also now available for all 5-inch reel LF models (LF510/LF550/LF557).
In addition, the new mower series features maintenance reminders that are displayed automatically on screen and scheduled intervals to aid in proper service and increased up-time.
Jacobsen is a Textron Inc. (NYSE: TXT) company.
