Slope Operation:
- Warning: Never operate on slopes greater than 17.6% (10°). Use front counterweights and rear wheel weights for slopes greater than 15% (8.5°) but less than 30%. Mow UP and DOWN slopes, never across.
- DOs: See dealer for wheel weights/counterweights, mow up/down slopes, remove obstacles, watch for holes/ruts/bumps, use slow ground speed, use extra care with attachments, keep movement slow/gradual, avoid starting/stopping on slopes.
- DON'Ts: Turn on slopes unless necessary (then slowly/gradually downhill), mow near drop-offs/ditches/embankments, mow on wet grass, try to stabilize with foot, use grass catcher on steep slopes.

- Manual Lift Assist Adjustment: Adjust tension bolt (clockwise to increase assist, counter-clockwise to decrease assist).
- Cruise Control Resistance Adjustment: Adjust tension screw (clockwise to increase tension).
- Steering Gear Adjustment: Loosen nuts, push bracket to mesh gears, tighten nuts.
- Electric PTO Clutch Adjustment: Check after initial 20 hours, then every 250 hours, or if slipping/not engaging. Use 0.012" feeler gauge to adjust nuts.
- Brake Spring Adjustment: Measure compressed spring length with parking brake engaged; adjust nut to achieve 2-1/2" (6.4 cm).
- Internal Neutral Adjustment: For Tuff Torq K71, K66, K62, K57 transmissions if tractor creeps. Block front tires, elevate rear, loosen jam nut, start engine, release brake pedal, adjust eccentric until wheels don't creep, secure jam nut, check pedal return.
Safety Interlock System Tests:
- Test 1 (Engine NOT crank): PTO switch ON, OR brake pedal NOT fully depressed (parking brake OFF), OR cruise control lever NOT in NEUTRAL.
- Test 2 (Engine SHOULD crank): PTO switch OFF, AND brake pedal fully depressed (parking brake ON), AND cruise control lever in NEUTRAL.
- Test 3 (Engine SHUT OFF): Operator rises off seat with PTO engaged, OR operator rises off seat with brake pedal NOT fully depressed (parking brake OFF).
- Test 4 (Blade Brake Check): Mower blades must stop within 5 seconds after electric PTO switch is turned OFF (or operator rises off seat).
Lift Variations When Using Attachments:
- Hydraulic Lift Models: Install downward pressure lock plate and additional pin for snowthrower/dozer blade. Remove for mower.
