Meet the T3100

• The Turfco T3100 is a self-powered, ride-on spreader/sprayer built for high-production lawn application of dry (granular) and liquid turf care products.
• Covers up to 4,000 sq ft per minute (240,000 sq ft per hour) spreading and/or spraying.
• 4-wheel machine with automotive-style steering — front wheels steer, rear wheels drive.
• Operator stands on a vibration-isolated platform at the rear; speed is controlled 0–5 MPH with a simple hand control and foot pedal.
• The machine stops automatically when the operator releases the speed control or dismounts.

Key Specifications

Operator Driving Controls

Before You Start — Daily Checklist

• Read the operator's manual and complete training before first use.
• Check the engine oil level and the transaxle fluid level.
• Check tire pressure (inflate to the PSI marked on the tire).
• Fill with fresh, approved gasoline — never refuel while the engine is hot or running.
• Inspect for loose nuts, bolts, hardware, or anything abnormal.
• Confirm all guards and covers are secure — never operate without them.
• Test every control from the operator platform before starting; check the platform locking knob is locked.
• Confirm the fuel shut-off valve is open and the parking brake is set before starting.

Learning to Drive

• Practice first in a large, smooth, paved area like a parking lot — not on a lawn.
• Stand on the platform, one hand on the support bar, one on the wheel. Release the brake, then squeeze the speed control forward slowly.
• Practice releasing the speed control repeatedly to get used to the automatic braking.
• Try reverse using the lever under the left support bar — slowly.
• Drive in all modes: fast, slow, turns, figure 8s, and backing — for at least 10 minutes.
• Practice at least 30 minutes in varied conditions and simulate tight spots (e.g., between a fence and an AC unit) before ever applying product.

Curbs, Slopes & Hills

• Use curb cuts and driveways whenever possible.
• Climbing a curb: approach at 45°, stop a few inches away, dismount, hold the wheel firmly, and walk the machine slowly over. Remount on top. Same technique going down.
• 15° is the maximum slope — period. Steeper slopes risk rollover; use walk-behind applicators instead.
• On slopes, drive at a 45° angle to the incline — never straight across the face of a slope at 90°.
• Do not turn the machine while on a slope or incline.

Spreader — Know the Components

Dry Application — Best Practice Routine

• 1. Walk the property first. Drive the perimeter slowly and note every obstacle, hole, rock, or hazard before applying anything.
• 2. Fill with the screen in place, using the product specified for the round.
• 3. Trim pass: Border Patrol ON, go clockwise around the outer edge, left wheels ~6 inches inside walks/drives, gate at the 60% Vari-Rate stop (spreading right only).
• 4. Obstacles: with the same trim settings, make a counterclockwise pass around trees, beds, and objects.
• 5. Fill passes: stripe the lawn, throwing product to the center of your trim tire tracks so you get 100% coverage with proper overlap.

Trimming & Narrow Areas

• Trim right, full width: Vari-Rate at 60%, Border Patrol ON, gate to the Vari-Rate stop. Pattern starts 2–3 inches left of the front tire and spreads right.
• Trim right, narrow width: same as above plus Spinner Speed to NARROW — ideal for boulevard strips between sidewalk and street (5–6 ft pattern).
• Narrow pass-through areas: Spinner NARROW + 60% gate = roughly a 9 ft or smaller pattern for gates and tight side yards.
• Use the 3½ MPH speed lever for better control while spreading tight areas — but never combine spreading and spraying at that speed; the calibrations don't match.

Sprayer — Know the Components

Spray Application — Best Practice Routine

• 1. Walk the property first — same perimeter inspection as spreading.
• 2. Trim pass: clockwise around the edge, left tire 2–3 inches off walks/drives, using the Trim Spray (3–4 ft wide, starting 2–3 inches left of the tire).
• 3. Obstacles: counterclockwise trim-spray pass around all objects.
• 4. Turning band: make a Full Spray pass 6 ft out from the trim tire track — this creates a ~13 ft band around the property for turning.
• 5. Fill passes: spray straight across; shut off at the band, make a 180° turn, and run the next pass 9 ft from your last tire track for proper overlap.

Calibration — Licensed Persons Only

• Calibration of gate settings, Vari-Rate stop, Accuway, and pump pressure is done only by licensed applicators — never adjusted in the field.
• Time your machine: 111 ft in ~15 sec = 1,000 sq ft per 15 sec at the 18/9 ft swath; 166 ft in ~23 sec = 1,000 sq ft at the 12/6 ft swath. Re-time periodically as the machine breaks in.
• Spreader: catch-and-weigh 60 seconds of flow (= 4,000 sq ft), adjust the gate dial until pounds match the product label rate.
• Sprayer: with water only, catch the full nozzle for 60 seconds, adjust pressure (start ~40 PSI) until you hit 1 qt/1,000 sq ft; verify pattern width on pavement (~2 ft wider than effective swath).
• Record everything — date, settings, product, and travel times in the calibration log.

Daily Preventative Maintenance

• Blow off fertilizer and debris every day with a blower or compressed air: around the axle (remove front hood), around/under the engine, inside and under the hopper (work the gate open/closed), and around the transmission.
• Wash with water when needed (high-humidity days or weekly). Be thorough — water + fertilizer residue is extremely corrosive. Blow the unit dry afterward.
• Variable speed pulley: clean with water while switching between wide and narrow. NO lubricant on the pulley. Blow water out with air.
• Spray filter: ball valve OFF, remove and rinse the filter (no high-pressure air or water — it damages the screen), replace, valve back ON. Wear PPE.
• Check engine oil and transmission oil levels.

Weekly Preventative Maintenance

• Grease all fittings: 2 front wheel spindles, 1 front wheel pivot (all years); front wheel fittings (pre-2011); steering arm (2016+). Wipe off excess.
• Engine air filter: tap clean; replace if excessively dirty.
• Carb linkage, choke, governor spring: blow clean, then work a DRY lubricant through the linkage (oil attracts fertilizer dust).
• Check tire pressure; check engine and transaxle oil; inspect V-belts for wear.
• Steering cables: check tension, adjust both sides evenly.
• Nozzles: clean trim and broadcast tips — never with metal objects (damages the tip and ruins the spray pattern).
• Check all cables (hopper gate, variable speed, throttle, trim guard) for smooth function.

Service Know-How & Seasonal Care

• Upright repair position: before tipping the machine up — empty hopper, drain tanks, ball valve off, remove battery and fuel, level surface, and use a properly rated lifting device that stays attached.
• Parking brake: if the machine moves with the brake on, the crown nut on the transaxle needs ½-turn adjustments (usually caused by driving with the brake on).
• Steering cables: tighten the clevis ends equally on both sides to keep alignment; 2015+ units have an adjustable stainless clevis. Front tires should toe out ¼–½ inch.
• Transaxle: 20W/50 oil; change oil and filter at break-in, then every 400 hours, and purge air afterward.
• Winterizing: flush the spray system, then run 1 gallon of RV antifreeze per tank through pump, valves, and tips. Battery on a maintainer; drain fuel or add stabilizer; full clean, grease, and inspection.

Safety DO's

• DO read the manual, warning decals, and complete training before first operation.
• DO wear the right PPE: safety glasses/face shield, gloves for chemicals and fertilizer, and hearing protection when needed.
• DO read and follow chemical labels and SDS sheets for every product you load.
• DO set the parking brake every time you leave the platform.
• DO shut off the engine before servicing, inspecting, or unclogging anything.
• DO keep all guards and covers in place and check brakes and controls before each shift.
• DO let the engine cool before refueling, and use fresh gas.
• DO dismount and walk the machine over curbs and on/off trailers.

Safety DON'Ts

• DON'T operate under the influence of alcohol or drugs, or with stereo headsets on.
• DON'T put hands or feet near moving or rotating parts — the spinner can throw objects at high speed.
• DON'T operate on slopes over 15°, or turn while on any slope.
• DON'T ride the machine while loading or unloading — ever.
• DON'T carry passengers or let children operate the machine.
• DON'T modify the machine, remove guards, or tamper with the governor.
• DON'T refuel indoors, near flames/sparks, or while the engine is hot or running.
• DON'T overload the hopper or tanks beyond rated capacity.
• DON'T adjust calibration settings (gate dial, Vari-Rate, pump pressure) unless you are the licensed person responsible.

Chemical Safety & PPE

• The T3100 does not protect you or bystanders from chemical exposure — during mixing, application, transport, or storage. Your PPE does.
• Read, understand, and follow the chemical manufacturer's label and SDS for every product — application rate, mixing, handling, and required PPE.
• Chemicals can be poisonous, cause burns, serious illness, or death. Protect against contact, inhalation, and overexposure.
• Wear gloves when handling chemicals and fertilizers; wear eye protection around application and rotary equipment.
• Premix products outside the tanks; never risk contaminating a water supply by placing a fill hose down into the tank.
• Know the signal words: DANGER = will cause serious injury or death; WARNING = could; CAUTION = may cause minor injury or equipment damage.

Transport & Final Reminders

• Loading/unloading: stand behind the platform and walk the machine up or down ramps using the speed control. Never ride it on ramps.
• Tie down by the frame only — never the hopper, tanks, or other parts.
• Freewheel lets you push the machine by hand — but it can roll away on slopes, so set the parking brake.
• Keep 1 gallon of water per tank when not spraying to protect the pump.
• Clean the machine daily — fertilizer residue destroys paint, parts, and bearings.
