Swath Roller Swath Board 34 Optional equipment Right-hand & Left-hand swath rollers The machine can be equipped with swath rollers as shown. Right-hand & Left-hand swath boards The machine can be equipped with swath boards as shown. 35 2 1 Hillside Kit As Seen From Below 225 mm(8-7/8”) 2-3 mm (5/16 - 1/8”) A 3 Inside High Skid B 4 Outside High Skid C 36 - - Optional hillside kit The spring lock keeps the machine in position in proportion to the tractor. If the machine meets a firm obstacle, the lock is released and the machine swings to the rear. Refer to the Hillside Kit Instructions for more information. The spring lock must be adjusted. Screw (A) is eccentric. Tighten the bolt to minimum 225 mm (8-7/8”) Refer to Hillside Kit Instructions.. Optional high skid The skids of the machine are fixed and cannot be height-adjusted. If the machine operates in fields with many stones, molehills, etc., high skids (B) and (C) are recommended. The cutting height is then increased to about 60 mm (2 -3/8”). Also refer to NOTE on page 25 for height adjustment. Fitting: Set of skids, 2 pcs., are to be placed in the right hand and left hand side of the machine. They must be fitted below the fixed skids as shown in photos 3 and 4. 37 Throwing Wings Flat Blades 2 Left Cone 38 . Special flat knives Special flat knives are recommended for rocky conditions. Special flat knives may be used on all models. However, for Models HM 2007 and HM2009, the number one cutting disc, next to the gearbox, must also be changed. The special flat knives and number one disc are available from your dealer. Throwing wings Throwing wings are recommended for very light grass conditions. Left cone The cone (B) at gearbox is standard equipment for model HM2008 and model HM2009. It is available for model HM2007 as extra equipment. The cone is recommended for mowing of long, wilted grass. 39 1 A 2 B 40 1.4 - 2.8 mm (.055 - .110”) 500 mm(19-5/8”) 0 - .05mm (0 - .002”) E F G H - Directions for repair Repair must only be carried out by competent persons with experience of using workshop equipment and trained in the repair of agricultural machinery in a safe and responsible manner. Stabilizer Be careful. Remove stabilizer from machine for disassembly. Never disassemble the stabilizer (A) without use of special tools (B). The spring is tightened to 800 - 1000 kg (1764 - 2205 lbs.). Special tools (B) are available. Hydraulic lifting cylinder New set of seals must be fitted as shown. Sealing rings (C) and (D) must be positioned as shown. Bevel gearbox NOTICE Repair of the gearbox must only be carried out by competent persons with thorough knowledge of such work. Tooth clearance must be within the stated values. NOTE THE FOLLOWING: Checking of tooth clearance (mesh) can only be measured on a clean and oil free gearwheel. Refer to gearbox repair manual for all gearbox repairs. Use a 500 mm (19-5/8”) long torque bar attached to the pinion shaft bolt when checking the tooth clearance. The stated values from 1.4 to 2.8 mm are valid with a 500 mm torque bar. Adjust tooth clearance with shims at (E). Adjust the slack of the roller bearing at the bevel pinion wheel by means of the washers (G) and (H). Sealing ring (F) must be turned as shown. Important, when fitting the gear to the machine: Use tab to lock the 8 bolts retaining the gear to the cutterbar. 42 -. Cutterbar NOTICE Be particularly attentive when checking or repairing the cutterbar - it rotates at 3000 rpm. Take care that worn bearings and gear wheels must be replaced in time. Otherwise a single damaged bearing might cause damage to the whole cutterbar. Use LOCTITE when stated - hardening time approx. 15 minutes. Intermediate gear (illustration 1) Inspection of intermediate gear can be carried out through the collar bearings holes. Intermediate gears can only be removed through the opening in the right hand side of the cutter- bar, but gear at (L) and gear at (T) (only model HM2007 and model HM2009) can be removed through collar bearing hole. These gears are smaller than the others. Note the following when replacing the bearings: When pressing out the bearing, sealing ring (A) is pressed into pieces. Use a new sealing ring when fitting a new bearing. Check that gasket (B) and (D) have not been damaged. The thread surfaces on bolt (C) must be locked with LOCKTITE type 242. The torque setting is Nm = 90 (66.4 ft./lbs.). Collar bearings (illustration 2) Press the bearing into the bearing housing. Mount the locking (E). Fill the hollow space (F) of the flange, shown at (F), with grease of good quality. NOTE: A tool kit is available for this procedure. Use a support on the inner race of the bearing when the flange axle is pressed into the bearing. P...
