Bush Hog HM2008 Lawn Mower User Manual


 
Height of the suspension
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 bot-
tom 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 dis-
tance 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 cor-
responds 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 pres-
sure 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 func-
tion will not work satisfactorily.
