Product Overview
The 345Pro Rotary Harvesting Unit by John Deere is a small-drum rotary header designed for harvesting a wide range of stemmed crops. It features small-drum cutting and gathering, advanced header-height control, row scrapers and cleaners to prevent crop build-up, lengthwise feeding and an open, serviceable design for reliable silage harvesting.

Key Features

• Small drum cutting: fast-turning saw blades cut across the full width for row-independent harvesting and effective performance in difficult conditions.
• Small drum gathering: intake fingers and low-speed gatherer drums guide plants into the drums, improving holding and cutting performance and reducing cob and crop losses.
• Advanced header-height control: optional Advanced Header Control (AHC) with a third sensor improves ground following to reduce wear and prevent wide headers diving into furrows.
• Row scrapers and cleaners to prevent crop build-up and maintain crop flow through the header.
• Lengthwise feeding: bundles are fed lengthwise toward feed rolls for even chopping; feed-drum sizing depends on header width.
• Open design: keeps crop flow clear and largely self-cleaning to reduce accumulation of debris and improve silage cleanliness.
• Serviceability: certain gathering-drum designs allow the top cover to be removed for easier access to intake fingers and faster cleaning/maintenance.
• Crop versatility: suitable for maize, sorghum, whole crop silage, oilseed, canola, pampas grass, miscanthus and other stemmed crops without needing separate specialized heads.
• 2024 update (middle section): longer front cover for the middle section protects cobs and can be removed to assist harvesting downed crops.

Benefits

• High cutting speed and row-independent design increase uptime and productivity.
• Secure crop guidance reduces losses and improves cut quality.
• Open, self-cleaning construction improves reliability in challenging conditions and reduces blockages.
• Advanced ground-following maintains header conformity to field contours, reducing wear and protecting crop quality.
