Mechanic & Equipment Maintenance Manual

🔧 Overview

The mechanic is the backbone of field operations. When a truck won't start, a sprayer clogs mid-route, or a Z-Spray throws a belt, every minute of downtime is lost production — lost stops, lost revenue, and frustrated technicians. Your job is to keep every piece of equipment in the fleet reliable, safe, and ready to perform.

This manual is your operating guide. It covers the equipment you're responsible for, the procedures you follow, and the standards you're held to. Read it, internalize it, and execute it daily.

📋 General Job Responsibility

You are responsible for:

1. Fleet readiness — Every truck, sprayer, spreader, and hand tool is operational and safe before the start of each work day
2. Preventive maintenance — Scheduled maintenance is completed on time, every time. Breakdowns are prevented, not just repaired.
3. Repair response — When equipment fails in the field or at the shop, you diagnose and repair it promptly
4. Parts management — You maintain adequate parts inventory, order replacements, and track usage
5. Safety compliance — All equipment meets safety standards. Sprayer calibration is accurate. Spill kits are stocked. Fleet vehicles pass inspection.
6. Documentation — Every task, repair, and parts usage is logged in The Yard's Mechanic App (see MAN-SYS-MECHANIC)

⏰ Daily Workflow

Priority Order

When multiple tasks are pending:

1. Safety issues first — Anything that could endanger a technician or customer (brake problems, leaking chemicals, damaged hoses)
2. Breakdown blocking a tech's route — Equipment failure that stops production today
3. Scheduled PM due today — Preventive maintenance on the calendar
4. Non-critical repairs — Issues that don't stop production but reduce efficiency
5. Cosmetic and organization — Shop cleanup, labeling, organization

🛠️ Your Tools

Physical Tools

• Standard mechanic's tool set (wrenches, sockets, screwdrivers, pliers, etc.)
• Sprayer calibration equipment
• Multimeter for electrical diagnostics
• Air compressor
• Jack and jack stands
• Parts washer / cleaning station

Digital Tools

🎯 Accountability

What Success Looks Like

• Zero delayed departures due to equipment issues — techs leave on time every day
• PM compliance at 100% — scheduled maintenance completed on schedule
• Rapid field response — when a tech calls with a breakdown, you respond within minutes
• Accurate documentation — every repair, part, and hour logged in the system
• Clean, organized shop — a mechanic's shop reflects their standards

What Gets Escalated

• Parts orders over a certain amount — manager approval required
• Equipment needing to be taken out of service for extended repair — notify manager immediately so the route can be reassigned
• Recurring failures on the same unit — document the pattern and recommend replacement or overhaul to the manager
• Safety defects that cannot be repaired same-day — the unit is tagged out of service immediately

🤝 Working with Technicians

Technicians are your customers. Their success depends on your work.

Expectations of Technicians

• Report issues promptly — via The Yard's fleet system or directly to you. "The sprayer's been making a weird noise for a week" is unacceptable.
• Basic daily care — Techs are responsible for: cleaning their equipment at end of day, checking fluid levels, reporting damage immediately (per MAN-LAWN-TECH Ch12)
• Don't modify equipment — Technicians are not to make repairs, adjustments, or modifications to sprayers, engines, or electrical systems. That's your job.

Your Commitment to Technicians

• If they report it, you address it — Nothing falls through the cracks. Every reported issue gets a response, even if it's "I'll get to it Thursday."
• Communicate timelines — If a repair will take a unit out of service, tell the tech and the manager how long.
• Quality work — A repair done twice is a repair done wrong. Fix it right the first time.

🔧 Overview

Knowing your fleet inside and out is non-negotiable. This chapter covers every category of equipment at Richter's and GreenX — the types, key specifications, common wear points, and what to watch for. Your equipment knowledge is what separates reactive repair from proactive maintenance.

🎯 Spray Equipment

Z-Spray Units

The Z-Spray is the primary ride-on spray/spread unit used by lawn technicians.

Common maintenance issues (from fleet records):

• Oil leaks — requires cleaning and monitoring for drips
• Foot plate springs — wear item, check regularly
• Engine cover and air filter cover — can become loose or damaged
• Caster bearings — front castors need regular inspection, tightening, or replacement
• Wheel bearings — both sides, check for play
• Idler pulley and belt — wear items, inspect for cracking/stretching
• Muffler — replacement due to heat/vibration damage
• Throttle cable — can stretch or fray
• Elbow for pump — connection point, check for leaks

Permagreen Units

Steel Greens

Hand-Can Sprayers

Used for spot treatments, perimeter applications, and areas inaccessible to ride-on units.

Maintenance: Clean after each use. Replace nozzles when spray pattern degrades. Check seals for leaks.

Hose Reel Units

🚗 Trucks & Vehicles

Lawn Division Fleet

Tree Division Fleet

Pest Division Fleet

Fleet Vehicle Maintenance Points

Regardless of make/model, every fleet truck requires:

🌱 Aeration Equipment

Per MAN-LAWN-TECH Ch14, aeration is offered as both mechanical (core aeration) and liquid service. Mechanical aeration equipment:

• Core aerator model: See equipment stored in shop — model varies
• Tine type: Hollow tine for core aeration (confirm with manager)
• Common issues: Tine replacement, engine maintenance, belt/cable wear

📦 Spreaders & Supplemental Equipment

📊 Equipment Assignment Tracking

Every piece of major equipment should be tracked with:

1. Unit ID — Unique identifier for each unit
2. Assigned technician — Who has it?
3. Current status — Operational, in shop, out of service, spare
4. Last PM date — When was preventive maintenance last completed?
5. Next PM due — When is the next scheduled PM?
6. Known issues — Open repair items

This is managed through The Yard's Mechanic App fleet view (see MAN-SYS-MECHANIC Ch04).

🔄 Spare Equipment

From fleet records, at least one spare Z-Spray unit is maintained ("Spare #1"). When a tech's primary unit is in the shop:

1. Assign the spare immediately — do not let a tech sit idle waiting for repair
2. Note the swap in the Mechanic App
3. Adjust the spare for the tech's preferences if time allows (seat, spray settings)
4. Return the repaired primary unit and recover the spare as soon as possible

🔧 Overview

Preventive maintenance is cheaper than repair. Repair is cheaper than replacement. This chapter covers the daily and weekly maintenance procedures that keep the fleet running and prevent the breakdowns that kill productivity.

🌅 Daily Procedures — Before Technicians Depart

Morning Walk-Through

Before techs arrive (or as they're prepping), walk the lot and inspect:

1. All trucks — Visual check for leaks under vehicles, tire condition, visible damage
2. Spray units — Quick check of tanks, hoses, and nozzles for obvious issues
3. Any units flagged from previous day — Check repair status, confirm ready for service

Urgent Repairs

If a tech reports an issue during morning prep:

1. Can it be fixed in 10 minutes? → Fix it now. Don't delay departure.
2. Will it take longer? → Swap to a spare unit. Schedule the repair for after departure.
3. Is it a safety issue? → The unit does not leave the lot. No exceptions. Swap to spare if available, and notify your manager immediately so the route can be handled.

📱 Daily Procedures — During the Work Day

Field Support

Be available for field calls/texts from technicians. Common mid-day issues:

End-of-Day Equipment Check

When techs return:

1. Visually inspect returned equipment — Any new damage? Leaks? Missing parts?
2. Check fluid levels if techs didn't top off (they should have — per MAN-LAWN-TECH Ch12)
3. Note any reported issues — Enter into Mechanic App queue
4. Charge batteries on any units that need it (tablets, electric start, etc.)

📅 Weekly Procedures

Complete these tasks once per week, rotating through the fleet so every unit is covered on a regular cycle:

Spray System Maintenance

Z-Spray / Ride-On Maintenance

Truck Maintenance

🧹 Cleaning Standards

Equipment Cleaning (Technician Responsibility)

Per MAN-LAWN-TECH Ch12 and Ch16, technicians are responsible for:

• Rinsing spray tanks at end of day
• Cleaning the spreader hopper
• General wipe-down of their Z-Spray
• Sweeping truck bed

Deep Cleaning (Mechanic Responsibility)

📝 Documentation

Every daily and weekly task should be logged:

1. Use the Mechanic App checklist (MAN-SYS-MECHANIC Ch04) for routine inspections
2. Log repairs as tasks with status, parts used, and time spent
3. Flag recurring issues — if the same part fails on the same unit repeatedly, document the pattern and recommend action to the manager

🔧 Overview

This chapter covers the most common repairs and troubleshooting procedures for the equipment fleet. The issues listed here come from actual fleet maintenance records and represent the repairs you'll encounter most frequently.

🏎️ Z-Spray / Ride-On Common Repairs

🛢️ Oil Leaks

Symptom: Oil drips under the unit; oil on engine block or frame

Diagnosis:

1. Clean the engine and surrounding area thoroughly
2. Run the unit for 10–15 minutes
3. Inspect with a flashlight — identify the source:
   • Valve cover gasket — oil seeping from the top of the engine
   • Oil drain plug — drip from the bottom center
   • Oil filter seal — drip near the filter housing
   • Crankcase seal — rear or front of the engine (more serious)

Resolution:

• Valve cover gasket → Replace gasket.
• Drain plug → Tighten or replace crush washer. Do not over-torque.
• Oil filter seal → Replace filter, ensure new seal is clean and lubricated.
• Crankcase seal → More involved repair. May require engine teardown. Consult manager on whether to repair or schedule with dealer.

🔩 Caster Bearings and Wheel Bearings

Symptom: Wobble, grinding noise, play in the wheel when you grab it and push/pull

Diagnosis:

1. Jack up the unit
2. Grab the wheel at 12 and 6 o'clock — push and pull. Any play = bearing issue.
3. Spin the wheel — grinding or roughness = bearing damage

Resolution:

1. Remove wheel and caster assembly
2. Remove old bearings (press or tap out)
3. Clean the hub
4. Press in new bearings — ensure they're seated fully and evenly
5. Reassemble, check for smooth rotation and no play

🦶 Foot Plate Springs

Symptom: Foot plate sags, doesn't return to position, tech reports bouncing or instability

Resolution:

1. Remove foot plate
2. Inspect springs for cracks, stretching, or deformation
3. Replace springs in pairs (both sides)
4. Reinstall foot plate and test

⚙️ Idler Pulley and Belt

Symptom: Squealing on startup, belt slipping, loss of drive power

Diagnosis:

1. Inspect the belt for cracks, fraying, glazing, or missing ribs
2. Spin the idler pulley by hand — it should spin freely without noise or roughness
3. Check belt tension — should deflect slightly with thumb pressure

Resolution:

• Worn belt: Replace. Always replace the belt when replacing a pulley.
• Frozen/noisy idler pulley: Replace the pulley. Check the mounting bolt/bracket.
• Belt routing: Verify correct routing per manufacturer diagram before tightening.

🔇 Muffler Replacement

Symptom: Loud exhaust, visible exhaust damage, rattle, or exhaust leak

Resolution:

1. Allow engine to cool completely
2. Remove mounting bolts/clamp
3. Remove old muffler
4. Install new muffler with new gasket if applicable
5. Tighten to spec — do not over-torque exhaust bolts
6. Start engine, check for exhaust leaks

🎛️ Throttle Cable

Symptom: Engine doesn't respond to throttle input, sticking, or snapping back

Resolution:

1. Inspect cable for fraying, kinks, or loose connections
2. Lubricate the cable with cable lube
3. If damaged, replace the cable:
   • Route the new cable along the same path as the old one
   • Ensure no sharp bends or pinch points
   • Adjust idle and full-throttle stop per manufacturer spec

🔌 Starter Replacement

Symptom: Clicking but no crank, slow cranking, intermittent no-start

Diagnosis:

1. Check battery first — load test. Rule out battery before replacing starter.
2. Check starter solenoid — does it click?
3. Bypass test if possible to confirm starter motor is the issue

Resolution:

1. Disconnect battery
2. Remove mounting bolts and electrical connections
3. Install new starter
4. Reconnect, test

💧 Spray System Troubleshooting

Low Pressure / No Spray

Uneven Spray Pattern

1. Clean/replace nozzles — The #1 cause. Worn nozzles spray wider or narrower than spec.
2. Check pressure — Low pressure = droplets too large, pattern too narrow
3. Check nozzle alignment — Are nozzles pointed correctly?
4. Recalibrate if nozzles were replaced — new nozzles may have different flow rates

Leaking Tank

• Crack — Small cracks can sometimes be repaired with plastic weld. Larger cracks = tank replacement.
• Fitting leak — Check O-rings and thread sealant on all tank fittings.
• Drain plug — Check washer, replace if worn.

🚗 Truck Troubleshooting

Won't Start

1. Battery — Jump start test. If it starts with a jump, test the battery and alternator.
2. Fuel — Is there fuel? (Yes, check this.)
3. Starter — Clicking = likely battery or starter solenoid. Nothing = possible ignition switch, fuse, or wiring.
4. Check engine light — If CEL was on, scan for codes.

Overheating

1. Coolant level — Check when cool. Top off if low. If it's losing coolant, find the leak.
2. Radiator — Check for blockage (bugs, debris, fertilizer dust). Clean with compressed air.
3. Thermostat — If coolant is full and fan works but temp is high, thermostat may be stuck closed.
4. Fan — Is the electric fan engaging? Check the relay and sensor.

Brake Issues

• Spongy pedal — Air in the lines. Bleed the system.
• Grinding — Pads are worn to metal. Replace pads and inspect rotors.
• Pulling — Caliper sticking on one side. Clean and lubricate slide pins. Replace caliper if frozen.

🔀 Troubleshooting Decision Trees

🔧 Overview

The best repair is the one that never happens. A consistent preventive maintenance (PM) program extends equipment life, reduces field breakdowns, and keeps technicians productive. This chapter covers PM schedules, seasonal changeover procedures, and winterization.

📋 Preventive Maintenance Schedule

Z-Spray / Ride-On Units

Trucks

Spray Equipment

📊 PM Tracking

Use The Yard's Mechanic App to track PM completion:

1. Each unit has a PM schedule in the fleet view
2. When PM is due, a task auto-generates in your queue
3. Complete and log every PM task with: date completed, hour reading (for equipment) or mileage (for trucks), what was done, any issues found, parts used

🌿 Seasonal Preparation

🌱 Spring — Pre-Season Setup (February–March)

This is the most critical maintenance period. Every unit must be field-ready before the season starts.

☀️ Summer — Mid-Season Maintenance (June–August)

The fleet is under maximum load. Focus on:

• Keeping up with PM schedules — Don't skip PMs because the fleet is busy
• Heat-related issues — Overheating engines, expanded hoses, battery drain
• Nozzle wear — High usage means faster wear. Replace proactively.
• Hydration and cooling — Equipment and people both need it

🍂 Fall — Aeration Season & Transition (September–November)

• Aeration equipment prep — Service core aerators before the season
• Product changeover — Clean spray systems when transitioning between round products
• Begin identifying winter repair candidates — Units with known issues that can wait for off-season repair

❄️ Winter — Off-Season & Winterization (December–February)

Off-season repairs: This is the time to tackle major repairs that were deferred during the season:

• Engine rebuilds or replacements
• Frame repairs
• Hydraulic system overhauls
• Truck body work
• Equipment modernization or replacement

📦 Parts Inventory Management

Stock Parts (Keep On Hand)

Ordering Process

1. Identify the needed part — use manufacturer part numbers when possible
2. Check shop inventory first
3. Order through your manager — they will direct you to the current supplier.
4. Log the order in the Mechanic App
5. When received, log receipt via The Yard Inventory Receiving form
6. Install and close the task
