Adjust the top link (A) to the minimum cutting height as shown at (B). PTO shaft Only use a tractor PTO shaft set for 540 rpm operation. It is dangerous to couple a tractor with 1000 rpm PTO output to a machine intended for 540 rpm PTO input speed. IMPORTANT PTO ADAPTERS SHOULD NOT BE USED WITH ANY BUSH HOG EQUIPMENT. FAILURE TO FOLLOW THESE INSTRUCTIONS WILL CAUSE DRIVELINE FAILURE AND POSSIBLE TRACTOR DAMAGE. When fitting the first time, before checking the shaft length, the top link must be adjusted to minimum cutting height (short top link). Follow this procedure: • Adjust the linkage so that the PTO stub shafts are level. • Fit the two parts of the PTO shaft onto the shafts of the tractor and the machine respectively. The clutch is placed at the machine end (C). • Place the two shaft halves together as shown at (D) and mark the shortening length (about 40 mm (1-1/2”) clearance). NOTE: Some tractor types do not require a shortening of the shaft. Shortening of the shaft When shortening the PTO shaft the four parts a - b - c - d must be shortened equally. After shortening, the tube ends and the shaft ends have to be filed off, cleaned of filings and lubricated. Checking of PTO shaft length NOTICE Fit the shortened shaft. Carefully check that the shaft does not bottom when the linkage is raised or lowered. Also check that the sliding tubes overlap with at least 150 mm (6”), when the machine is in the working position. This check should always be carried out when the machine is coupled to the tractor. If the tractor is replaced the above check must be carried out and if necessary a new adaptation of the shaft must be done. 23 450 - 480 mm (Model HM2009 - max. 450 mm/18”) (18” - 19”) Model HM2007 - 13mm (1/2”) Model HM2008 - 11mm (7/16”) Model HM2009 -8 mm (5/16”) min. 950 mm (38”) * 450 - 480 mm (Model HM2009 - max. 450 mm/18”) (18” - 19”) Model HM2007 - 13mm (1/2”) Model HM2008 - 11mm (7/16”) Model HM2009 -8 mm (5/16”) min. 950 mm (38”) * 24 Height of the suspension Important The working height of the suspension 450 - 480 mm (18 - 19”) is maintained with the chain (A). The chain is locked as shown at (B). NOTE: If the machine is equipped with high cut skids the working height of the linkage must be 500 - 530 mm (20 - 21”). If these settings are not adhered to, it could result in excessive wear to the skids and gearbox bushings, and cause abnormal wear on the breakaway assembly. Stabilizer Check the movement area (C) of the stabilizer when the machine is in the field and lowered to the working position. If necessary adjust the right hand lift arm of the tractor (D): If the distance (C) is too big, raise the lift arm at (D) and oppositely if the distance is to small. NOTE: Adjustment of the lift arm is easier to carry out when the machine does not load it - therefore raise the machine, engage pawl, shown at the bottom of page 26, remove suspension chain and lower the machine to the ground. * Applies especially for model HM2009 To assure an optimum ground following ability, it is recommended to work with a distance of 8 mm (5/16”) at (C) on even land. When working on uneven land, it is recommended to use a bigger distance than 8 mm (5/16”), but note that the lifting height of the machine will then be reduced when turning in the field. Read more about lifting height in the following paragraph. Check that the distance from the suspension to the ground does not exceed 450 mm (18”). See Fig. 1. Lifting height The lifting height of the tractor must be at least 950 mm (37-1/2”) as shown. This lifting height corresponds to a ground clearance of approx. 300 mm (12”) at (E) and 420 - 520 mm (16-1/2 - 21”) at (F) depending on machine type and tractor size. If the ground clearance is too small, check the adjustment of the stabilizer. Also check tire pressure in the right hand rear wheel of the tractor. Lifting bracket (G) from the factory is fitted in the shown standard position. If the bracket is fitted in the holes (H) the ground clearance will be larger at (E) but smaller at (F). NOTICE Make sure that moveable parts are lubricated as shown on page 18. If not lubricated, lifting function will not work satisfactorily. 25 1 Transport Position 2 E B A 5 E 4 D C 6 Un-Hitched Support Legs F Chain 7 G Lock Pawl Engaged 26 -. -. Transport - Unhitching Transport As shown the machine can be raised to the vertical position. Raise the machine clear of the ground with the lift arms (A) of the tractor, then raise the machine to the vertical position with the hydraulic cylinder of the machine. Be careful, check that the curtain frame of the machine can clear the rear wheel of the tractor at (B): If necessary the curtain frame can be turned forward by disengaging the pawl (C). Be careful. Make sure that no persons are near the machine when it is being raised or lowered during transport. Lock the machine with “L” pin (D) and retaining valve (E). The “L” pin is placed in the hole on the left hand side, when the machine is lowere...
