20 Hydraulic Assembly. Specifications Deck Configuration: Out front deck with a right hand trim offset. Four individual chambers jointed for articulation.
One blade per chamber. Cutting Width: 82 inches (2.1 m). Chamber Housing: 12 GA. Steel, 4.5 inch (114 mm) deep, welded construction and reinforced with 10 GA high strength formed plates. Height–of–Cut (HOC): 1 inch (25 mm) to 4 inch (102 mm) by 1/4 inch (6 mm) increments. Blade Size: Four 22 inch (559 mm) long by 2.50 inch (64 mm) wide by.25 inch (6 mm) thick heat treated steel with formed parallel sails.
Blade Overlap: 2 inch (51 mm) in the flat configuration. Blade Drive: Hydraulic drive via a PTO driven high efficiency gear pump on the traction unit integrated hydrostatic transaxle (IHT). Four integrated spindle motors operated in a series configuration through SAE–10(.625) high pressure wear resistant hoses with high density polyethylene protective tubing. Spindle motor is a high efficiency pressure balanced gear motor with a direct drive to the spindle shaft operating in a constant wet lubrication on two Teflon coated journal bearings. Welded blade retainers mounted through a tapered joint with a 2 inch (51 mm) high outer shield to protect spindle seals. Hydraulic braking valve set to 600 PSI (41 Bar) to achieve a complete blade stopping time of 5 seconds from full engine (PTO) speed.
Blade Speed: 15,724 feet (4,793 m) per minute tip speed (2730 rpm spindle speed) at 2795 rpm on diesel models and 3275 on gas models. Suspension & Castor Wheels: Five front castors and three rear castors, consisting of 8 inch (203 mm) pneumatic wheels with sealed ball bearings.
One rear link suspended from the right lift arm. Hydraulic counter balance and lift system designed integral with deck for maximum floatation. Anti–Scalp Features: 11 inch (279 mm) diameter anti scalp cups located.75 inch (19 mm) below each blade.
Adjacent chambers pivot freely about two independent 60 opposed hinges down –20and up +20. 1 inch (25 mm) diameter anti–scalp/wearskids located on each outside chamber. Discharge: Evenly dispersed rear discharge between the outside width of the deck with partial recycling rear baffles. Lift/Transport: Stainless steel cables from outside chambers to nearest lift arm actuated via a lever on the lift arms. Complete deck is lifted via the traction unit lift system.
Counter–Balance: Recommended operating counter balance pressure of 125 PSI (9 Bar) set by an adjustable counter balance valve on the traction unit. Overhang/Trim: Deck is offset to the right of the traction unit to provide overhang of 21 inch (533 mm) on the right and 8.25 inch (210 mm) on the left with deck in a flat configuration. Uncut circle is 16 inch (406 mm) on right with no brakes. Covers: No complete deck covers required. Hydraulic hoses to be covered per ANSI/ISO standards. Connect/Disconnect: Use existing GM 3000 style of quick attach lift arm system.
For ease of cleaning and maintaining oil cleanliness, the hydraulic lines use flush face quick couplers for pressure supply line, return line, braking sense line, and motor case drain line. Sound Levels: Operator ear to be 90 dBA per SAE measuring standards. Safety: Deck and traction unit to comply with ANSI B71.4–1990and CE compliance. Productivity: Mows up to 4.6 acre (1.86 hectare) per hour at 5.5 mph (9 km/hr) Approach Angle: Minimum approach angle (for trailering) of 11.5 at highest HOC setting. Weight: 745 lbs (338 Kg). Height of Cut Adjustment The height–of–cutis adjustable from 1 to 4 inches (25 to 102 mm) in 1/4 inch (6 mm) increments.
Start the engine and raise the cutting unit so height– of–cutcan be changed. Stop engine after cutting unit is raised. Front Castor Wheels 1. Remove H.O.C. Cap from spindle shaft and slide spindle out of front castor arm. Slide spacers onto spindle shaft to get desired height–of–cut.
Push castor spindle through front castor arm install remaining spacers onto spindle and install HOC cap to secure assembly. Deck Pitch Adjustment Deck pitch is the difference in height–of–cutfrom the front of the blade plane to the back of the blade plane. For the Contour 82, TORO recommends a blade pitch of 7/16 inch (11 mm). That is the back of the blade plane is 7/16 inch (11 mm) higher than the front.
Position machine on a level surface on shop floor. Set deck to the desired height–of–cut. 3 chamber blade so it points straight for- ward.
Using a short ruler, measure from floor to front tip of blade. Then, measure from floor to rear tip of blade.
Subtract the front dimension from rear dimension to calculate your pitch. To adjust pitch, start traction unit and raise deck to highest possible position and turn off engine. Loosen jam nuts on top or bottom of Height–of–Cutchain U–bolt.
Adjust other set of nuts to raise or lower rear of No. 3 chamber and attain correct deck pitch. Tighten jam nuts. Service and Repairs CAUTION To prevent accidental starting of the engine, while performing maintenance, shut engine off and remove key from ignition switch.
Grease Bearings and Bushings The cutting unit must be lubricated regularly. If machine 1. The cutting unit has (19) bearings and bushings that is operated under normal conditions, lubricate castor must be lubricated, and these lubrication points are: bearings and bushings with No. 2 general purpose lithi- front castor shaft bushings (5), chamber pivots (12) and um base grease or molybdenum base grease, after ev- right and left push arm ball joints (2).
Ery 50 hours of operation. Lubricate fittings immediately after every washing, regardless of the interval listed. Disconnect Cutting Unit from Traction Unit Note: Implements are heavy and may require two people to handle. Start traction unit and raise deck to highest possible position and turn off engine. Remove hair pin cotter and clevis pin securing height–of–cutchain to rear height–of–cutbrackets on chamber 3. Rotate ignition key to run position and move lift lever forward to lower cutting unit. Raise seat and open needle valve.
This allows lift arms to float freely. Remove hair pin cotter and clevis pin securing latch cover to lift arm. Loosen release lever by rotating it counterclockwise. Pivot release lever upward and remove shaft latch from slot in traction unit lift arm. Disconnect hydraulic line quick couplers from traction unit.

Stay clear of lift arms and move deck away from traction unit allowing lift arms to fall. Secure hair pin cotter and clevis pin to height–of–cut chain for storage. Close needle valve.
