8. PTO Shield:
- All snowblowers are supplied with a PTO shield. Bolt the shield 965410 (965409) to the
hinges on the top of the gearbox on both the 740 and 840 snowblowers using 1/4" x 1/2"
hex bolts, lock washers and hex nuts. Insert a 3/16" cotter pin in the hole in the shield and
in the hole at the bottom corner of the gearbox. Fold back the cotter pins to hold them in
place. Hook the ends of the spring (960135) into these cotter pins to hold the shield down.
To mount the shield 965410 (965409) on the 840G snowblower, remove the two rear bolts
at the top of the gearbox (BU50506). Bolt the PTO shield to the gearbox plate using these
same bolts. Insert a 3/16" cotter pin in the hole in the shield and fold to lock in place. Hook
one end of the spring (960135) into this cotter pin and the other end into a hole in the lower
gearbox plate to hold the shield in place.
CAUTION
Do not run the snowblower without this shield in place.
