ASSEMBLY

g

1. Unpack the drive and deck.

2. Remove the belt covers, fig 1, Items 27.

3. Mount the idlers on the studs as in fig 2. Note the
different sleeve lengths of the idlers. The short
sleeve goes next to the high rotor and the tall
sleeve goes next to the low rotor. Set the idlers
on the studs with the extended sleeves down.
Work from the rear of the mower.

7. Bolt the drive to the deck. The 2 carriage bolts
are inserted from under the deck, fig 1, Items 41,
42 & 43. Be sure that the heads seat properly in
the deck. The 3 hex bolts fasten from the top, fig
1, Items 29 & 40. Start all bolts and nuts before
tightening.

5. Hook the springs to the idler assembly from
underneath as in figs 2 & 4, solid lines.

bolt
it down. Slip the belts on the drive pulley and
then on the rotor pulleys. Let the idlers float at
this time; solid lines, fig 4.

10. Install the bushings in the caster wheels and

bolt the wheels in the caster forks.

HOURS of operation or more often when

operating in severe dust or sand.

2. Grease the bronze bearing and caster wheels through
the grease fittings with general purpose grease fig 1,
Items 38 & 49. Add grease until it comes out the
