Straight hitchFor an economical alternative to theKuhn GYRODINE swivel hitch, the FC 302 model is available with astraight hitch.

Exceptional turningability in situations where it is almostimpossible to turn with a straighthitch model. Reliable and chatter freeoperation as the PTO shaft is alwaysperfectly aligned with the tractoraround the tightest thanks to quick attachment, 2-input shaft (540 and1000 rpm) speeds, productivity, andease of operation even in cutting-conditioning head is driven by a transmissionshaft, which unlike other types of drive systems, keepsmaintenance to a minimum. The overrunning clutch protects the Mower conditioner and the tractor PTObrake when the PTO is shut adjustable friction slip clutch protects drive components from Intermediate PTO shaft drive with free wheel2.

With a KUHN Mower conditioner, carefuldesign and quality constructionmaterials and techniques leave nothing to CONDITIONERSFC 302 / FC 3521. Specially designed discsAn oval shaped disc offers numerousadvantages over other crop is ejected quickly andthe knives have a greater overlap for a cleaner cut. The larger diameter of the disc , especially designed for trailed FC mowerconditioners, positively supplies cut material to the conditioning unit for optimum A compact and flat, compact cutterbar hasa streamlined shape so soil and crop residue do not accumulate, the cut crop flows cleanly over the cutterbar, even in dense Cutterbar protectionExtra rigidity is ensured with the cutterbar gearcase mounted inside a steel cradle with a rear stiffener.

7 One-piece disc guards and skid shoes are made of heat-treated steel to protect the are attached to the front and rear of the cutterbar assemblywhich makes them easily replaceableif necessary. Deflector shields are fitted between the disc guards to2protect the cutterbar from beingstruck by knives bent should an obstacle be Reinforced and easilyreplaceable knivesKuhn knives are made of high quality steel and manufactured to very strict standards. For safetyand long life, knives are secured with specially designed bolts madeof special steel, not with quick fastening knives are easily changed or reversed with the help of a boltaccess hole at the front of the Protectadrive cutterbarprotection systemThe Protectadrive disc protectionsystem normally protects the geartrain should a major obstacle bestruck in the field.

8 Fast and easyremoval and installation of the disc bearing station without the need to remove the cutterbar fromthe machine minimises downtimeand costs. Protectadrive is exclusive to of Finger/Comb or roller for made to measure ! natural wax coating on thestems and leaves is broken down dueto friction between the crop and thefinger and comb. The smooth roundsides of the fingers ensure that tho-rough conditioning occurs withoutaggressively stripping the leavesfrom the Kuhn Finger/CombConditioning SystemWith an adjustable 2-sided reversiblecomb (A and B), a Kuhn FC mowerconditioner can be quickly adapted to different crops and various condi-tioning needs. The round side of thecomb provides gentler conditioningwhile the aggressive T side of thecomb is used to meet heavy conditio-ning requirements. Round and smooth forged steel fingers are usedso that the crop is not damaged bysharp edges.

9 For even more adjust-ment, the speed of the rotor may bechanged by swapping the Comb adjustmentConditioning intensity is quicklyadjusted with a conveniently located lever. Five positions adjustthe conditioning from maximum to minimum. Should a foreign objectenter the machine, the comb is spring loaded to swing back and then automatically return to its original Stages of conditioning crop enters the conditionerwith the cut end first. The rest of the crop is then drawn through conditioning process conti-nues along the length of the stem asit passes through the system.
