MAINTENANCE
TRANSAXLE BELT: REPLACEMENT
(Tools required…2 x 13mm spanners, 1 x phillips head screwdriver.)
• To remove the belt, firstly remove the top cover by withdrawing the 4 securing screws.
• Loosen the nuts on the top end of the vertical control rod using two 13mm spanners. Screw the lower nut down
on the thread so the tension on the belt from the idler pulley is minimised.
• From behind the mower, roll the drive belt off the engine pulley. Then withdraw the belt from the front pulleys.
• Replace the belt with a new belt (Deutscher part No. 1579), and ensure the belt is inside the guide pins.
• Re-adjust the vertical rod length using the two nuts so the drive belt is taught when the hand lever on the right
handle is just touching the rubber handle grip. Excessive belt tension may not improve drive traction and may
cause premature belt wear.
CUTTER BELT: REPLACEMENT, including BLADE BRAKE ADJUSTMENT
(Tools required…2 x 18mm open ended spanners, 2 x 11mm open ended spanners, 1 x phillips head
screwdriver. )
• To replace the cutter belt, first remove the top cover. Next ensure that the drive belt is disengaged, by raising
the foot pedal on the rear of the mower.
• Fully loosen the front ¼” nut on the blade brake rod alongside the left rail of the mower.
• Loosen the two large 12mm nuts on the threaded rod attached to the cutter spindle. Wind the nuts by hand on
the threaded rod to allow the cutter deck to be pushed fully back in its slides.
• Remove the transaxle drive belt as described above.
• Install a new blade drive belt and then replace the transaxle drive belt.
• Readjust the two 12mm nuts by hand tightening them, engaging the blade drive foot pedal and checking the belt
tension. The easiest way to test the tension is to squeeze the belt together somewhere near the centre between
the two pulleys. The belt should only move in about 15mm on each side.
• Securely lock the two 12mm nuts.
• Re-adjust the blade brake rod by engaging the clutch and moving the brake pad so it is 1-2 mm clear of the
spindle pulley. Tighten the 1/4” nuts.
• Test run the mower, keeping well clear of the drive belts. Ensure that the blade brake operates when the blade
drive clutch is disengaged.
BLADES
• It is important that you visually inspect the blades, bolts and nuts to ensure that they are in a safe operating
condition; this should be done before each mowing period.
• Always replace blades and bolts in kit form to prevent any vibration that may damage the mower and cause
personal injury.
