until the brake pedals have 13 to 25 mm (1/2 to 1
inch) of free travel.

Belt Maintenance
Servicing the Alternator Belt
Service Interval: After the first 10 hours
Every 100 hours
Check the condition and tension of the belt
every 100 operating hours.
1. Proper tension will allow 10 mm (3/8 inch) deflection
when a force of 44 N (10 lb) is applied on the belt
midway between the pulleys.
2. If the deflection is not 10 mm (3/8 inch), loosen the
alternator mounting bolts
decrease the alternator belt tension and tighten the
bolts. Check the deflection of the belt again to ensure
that the tension is correct.

Belts
Service Interval: After the first 10 hours
Every 50 hours
Check the condition and tension of the cutting unit drive belts
initially after 10 hours of operation and every 50 operating
hours thereafter.
When properly tensioned, the extension spring (hook to
hook) measurement should be approximately 8.9 cm ± .63
cm (3.50 ±.25 inch) (inside). Once the correct spring tension
is attained, adjust the stop bolt (carriage bolt) until there
is approximately .32 cm ± .152/.000 cm (.125 +.060/-.000
inch) clearance between the head of the bolt and the idler
arm
