Briggs & Stratton 5900834 ユーザーズマニュアル

 1.  Park the machine on a flat, level surface.  

Disengage the PTO, stop the engine, and engage 
the parking brake.  Rear tires must be inflated to 
18 psi (1,24 bar).

 2.  Measure and record the distance between the lift 

pivots and the rod pivots.  Repeat for the other 
side of the unit.  See Figure 37.

 3.  If the measurements for the lift pivots and rod 

pivots are equal, no further adjustment is required.  
If the measurements are NOT equal (greater than 
1/8” (3,17 mm) difference), adjustment is required, 
continue with Step 4.

 4.  Lower the mower deck to the lowest cutting 

position.

 5.  Block up the mower deck until all of the hanger 

chains are slack.  See Figure 38.

 6.  Refer to Figure 39.  To adjust the lift rod, loosen 

the jam nut on the front ball joint then remove 
the 1/2” hardware fastening the ball joint to the 
lift pivot arm.  Turn the ball joint CLOCKWISE to 
shorten the distance between the rod pivots or 
COUNTER-CLOCKWISE to lengthen the distance 
between the rod pivots.  Reinstall the ball joint on 
the lift pivot arm and secure with the 1/2” hardware 
previously removed.  Tighten the jam nut against 
the lift rod.

 7.  Remove the blocks from under the mower deck.

 8.  Adjust the cutting height to the desired position.
