common to all 700 series, and plastic inserts will

1.6. Spotter's Guide: The 700 series is visibly simi-
lar to the existing step-through platform 600 and
610 series lawn tractors, but there are substan-
tial differences.
• Drive System: Hydro The 790 series de-
clutches the traction drive belt when the clutch/
brake pedal is depressed, without moving the
fender-mounted transmission control lever. In
contrast, the 610 series hydro is controlled by a
foot-operated rocker pedal. The operator of the
610 series must remove their foot from the
rocker pedal to apply the brake. The rocker
pedal is spring-loaded to return to neutral.
• Drive System: Non-hydro The 770 and 600
series transmission are both operated by a gear
selector lever on the right fender. Ground
speed is controlled by a clutch/brake pedal on
the left side of the 770. Ground speed is con-
trolled by an automotive style drive pedal and a
separate brake pedal on the right side of the
tractor on the 610 series. The variable speed
pulley principal is the same, but pedal operation
is reversed.
• Deck Engagement: The PTO belt is engaged
on the 700 series using a lever on the right
fender. The 600 series uses a dash-mounted
lever or an electric PTO clutch.
• Decks: While the 700 series accepts only an F
or G deck, the 600 series will accept a variety of
decks that include 46" (H deck), 50" (P deck).
Both series have Fast-Attach
600 series has "J" pins to connect the rear of the
deck, while the 700 series decks are secured
directly to the lift rods and lift links by locking
internal cotter pins ("hairpin clips" that resemble
a bow-tie in configuration).
