STRONGER, LESS MAINTENANCE
The replaceable inner skin on cutterbar access hoods helps to reduce possible damage to outer cover for improved resale value.
MacDon’s engineers have substantially strengthened the R85’s header frame by making sure that the top link, lower lift arms and all header parts are anchored or bolted into sturdy frame members. Operators will also appreciate the R85’s lower maintenance requirements thanks to its fewer moving parts than mechanical drive designs, and greasing intervals of 25 and 50 hours.
CUT LOWER, CUT CLEANER, CUT FASTER
To help you cut lower and at a flatter angle we’ve both lowered the profile of the cutterbar and strengthened the design of the cutterbar cradle. These improvements combined with the R85’s sturdy frame design and excellent spring flotation system allows you to run the machine faster over rough terrain and still maintain a consistently clean cut.
IMPROVED CAPACITY AND CROP HANDLING
We’ve given the 16' (4.9 m) R85 an overshot auger to more efficiently transfer crop from the discs to the wide conditioner rolls and improve cutting performance in tougher conditions.
The R85 boasts a number of new features that improve capacity and crop handling. These include an optimized disc rotation pattern to reduce the amount of debris thrown across the cutterbar, and newly added accelerators on each disc to promote better crop flow in thick and tangled crop. Together, these improvements add up to significantly increased cutting capacity, reduced crop stripping and improved windrow formation.
NEW OVERLOAD PROTECTION
R85 cutterbars feature a single removable key on the outside hubs that will shear if the disc comes in contact with an object that stops its movement. The hub can then be removed and the key replaced, allowing the operator to quickly get back to cutting.
DOUBLE WINDROW ATTACHMENT
MacDon’s optional Double Windrow Attachment allows you to place up to 48' (14.6 m) of conditioned crop with the R85 into a single windrow.
WIDEST CONDITIONING ROLLS ON THE MARKET
To improve conditioning performance, the R85 Rotary Disc has been equipped with the widest steel on steel rolls on the market (118"/3000 mm). Wider rolls increase the amount of crop contact, improving crimping performance and ensuring thorough conditioning of the plant stem. These conditioning rolls also feature a design which more aggressively pulls crop away from the cutting discs, for reduced power requirements and improved performance.
