A motor grader is the one machine on the job that's judged by millimeters. A wavy road base, a shoulder that won't hold grade, a pass the crew has to redo — it's almost never the operator; it's slop that crept into the circle, the moldboard, or the articulation and nobody caught it. Motor grader inspection and maintenance software keeps that wear visible, flagged, and fixed before a $500 service turns into a $125,000 rebuild and a scrapped grade. See how a grader-specific inspection, defect flow, and hour-based PM keep the blade true, then book a demo to map it to your graders .
Keep the Blade True. Catch the Slop Before It Shows in the Grade.
Grader-specific digital inspections for the moldboard, circle, drawbar, and articulation — defects flow straight to a work order, and PM fires on real meter hours.
Every other machine is judged by how much it moves; a grader is judged by how precisely it finishes. That precision runs through a chain of linked components — the blade hangs off the moldboard, the moldboard rides the circle, the circle turns on the drawbar, the drawbar pivots at the articulation, and hydraulics position all of it. Wear anywhere in that chain shows up as a wavy pass, a blade that chatters, or a cut that won't hold grade. And the cost of ignoring it is brutally nonlinear: a routine $500–$2,000 service deferred too long becomes a $15,000–$125,000 emergency repair. The inspection isn't paperwork — it's what protects the grade and the machine.
The blade-accuracy chainevery link that has to be tight for a grader to hold grade
A grader's accuracy is only as good as the weakest link between the engine and the cutting edge. Slop in any one of these multiplies down the chain into a bad pass. A grader-specific inspection walks the whole chain — here's what each link is, and what wear looks like.
Cutting edge & end bits
The consumable that actually touches the ground. Worn edges and end bits directly degrade grading precision — check wear and bolt torque weekly, keep spares, and flip or replace on time.
Moldboard & wear strips
The blade's mounting. Loose or worn moldboard wear strips cause chatter — the telltale ripple in the finished surface. Shim and align them before the operator feels it in the controls.
Circle & circle drive
Rotates and holds the blade angle — and it's the single most expensive system on the machine. Watch wear strips and shoes, gear-tooth wear, the slip clutch, and greasing. Unshimmed circle = imprecise cuts.
Drawbar & ball-and-socket
The A-frame linking the blade group to the front frame, pivoting on a ball-and-socket. Play here telegraphs straight into blade position — inspect the socket, pins, and mounts for slop.
Articulation hitch
The pivot between front and rear frames, riding a large tapered roller bearing. Debris buildup, dry pins, a worn bearing, or a failed locking pin all rob the machine of control — and the bearing is a costly fix if it's run dry.
Hydraulics
Position every blade movement. Cylinders, hoses, tubes, and fittings for leaks and drift; filter changes and oil sampling on schedule. A drifting circle-shift cylinder makes a straight pass impossible.
Because the circle drive and hydraulics together carry around 35% of a grader's maintenance cost — and all of its accuracy — those links are where inspection discipline pays back hardest. HVI's grader-specific inspection puts each link on the checklist with photo capture, so slop gets logged while it's a shim, not a rebuild. Start a free trial and load your grader template this week
Why deferring a grader PM is a gamblethe nonlinear cost of a skipped service — and the uptime it protects
The temptation on a busy job is always the same: the grader still cuts, so push the service another week. The problem is the math. Grader wear doesn't fail gracefully — it compounds until a cheap service becomes a catastrophic one.
That's the entire argument for hour-based PM that actually fires instead of slipping. A flagged wear item on an inspection becomes a scheduled work order, not a note that gets forgotten until the circle drive lets go. Book a demo to see grader PM that doesn't slip
From flagged defect to closed work orderwhy a digital grader inspection beats a paper one every shift
Paper finds the worn wear strip and then loses it on a clipboard. Digital turns the same flag into tracked work. On a machine whose value is a precise cut, that gap — between spotting the slop and fixing it — is exactly where bad grade and big repairs come from.

1
Operator runs the pre-shift inspection
A grader-specific checklist on a phone or tablet — blade, circle, drawbar, articulation, hydraulics, tandems, tires — in a quick walkaround, with photos, before the machine cuts.
-
2
A defect is logged with photo & severity
Blade chatter, circle play, or a hydraulic weep gets flagged with a photo and severity, tied to that exact grader — not a scribble that's illegible by end of shift.
-
3
It becomes a work order in one tap
The fault converts to a work order with details and photos attached, assigned to a tech and visible immediately — so the wear strip gets shimmed before the circle gear is chewed.
-
4
Parts, labor & sign-off recorded
Parts used deduct from inventory and link their cost to the job; labor logs against the grader; the tech closes it out on-site. The repair's real cost is captured, not estimated.

5
It lands in the machine's history
Every inspection and repair writes to the grader's record and feeds cost-per-hour analytics — so you can see which machine costs the most to keep cutting and why.
PM that fires on hours, not memorymeter-hour preventive maintenance tiers for motor graders
A grader wears by the hour, and its PM is a tiered schedule the meter drives. Tie each service to real operating hours and the greasing, the blade checks, the circle service, and the oil analysis all happen on time — and severe dust or heat simply tightens the intervals.
Daily walkaround and greasing; weekly cutting-edge and end-bit wear checks, blade bolt torque, and wear-strip condition.
Oil and filter service, circle inspection and shimming, hydraulic checks, articulation and tandem service. Severe duty pulls 500 hr to 250–300.
Oil analysis across systems, circle-gear and wear measurement, final-drive and tandem analysis, frame and linkage inspection.
HVI auto-generates the work order when a grader's hours cross an interval, with the standard tasks and parts kit already attached, and alerts you before it's due. Meter-hour PM scheduling turns "we'll service the circle next week" into a service that actually fires. Book a demo to see tiered PM on your grader models
The motor grader pre-shift checklistwhat every grader inspection should cover before the blade drops
This is the daily walkaround that keeps a grader cutting true and safe. In HVI it's a guided template — tick, flag, photo — so nothing gets skipped when the job's pushing to finish grade and a defect flows straight to the shop.
A pre-shift inspection is also an OSHA expectation for powered construction equipment (29 CFR 1926.602) — run it on paper and the record scatters; run it in HVI and every walkaround is a signed, photo-backed record. Book a demo and see the grader checklist live on one screen
From a grading superintendent who chases the millimeters
People think a bad grade is a bad operator. Nine times out of ten it's the machine — a circle that's gone sloppy, a worn wear strip putting chatter in the blade. My best hand can't cut a clean shoulder if the circle has play in it, and he'll fight it all day before anyone writes it down.
Putting it on the daily inspection changed that. He flags the blade's feeling loose, there's a photo, and it's a work order that gets the wear strips shimmed before we've cut a whole stretch that has to come back out. We also stopped losing the big one — a circle drive you catch early is a service; one you run to failure is fifteen grand and a week. The inspection pays for itself the first time it saves a grade.

Frequently asked questions
What is motor grader inspection software?
It's a mobile-first digital checklist built around a grader's systems — moldboard, circle, drawbar, articulation, hydraulics — that flags defects with photos and sends them straight to the maintenance team. Book a demo to see it on your graders.
What are the PM intervals for a motor grader?
Typically a daily walkaround with weekly blade checks, basic service at 250 hours, intermediate at 500, and major service at 1,000+ hours with oil analysis. Severe dust or heat can pull the 500-hour interval to 250–300. HVI sets each per model. See it in a demo.
How does grader wear affect grading accuracy?
Worn cutting edges, loose moldboard wear strips, and play in the circle or drawbar all telegraph into blade position — causing chatter and imprecise cuts. Catching them on inspection protects the grade. Book a demo to see the blade chain tracked.
Why is the circle drive so important to maintain?
The circle drive and hydraulics carry around 35% of a grader's maintenance cost and all of its blade accuracy. Caught early a circle issue is a service; run to failure it's a five-figure repair and lost days. Book a demo to see circle tracking.
How does a defect become a repair in HVI?
A flagged defect converts to a work order in one tap, with the photo and details attached and assigned to a technician. Parts and labor log against the grader, and it closes out on-site. Start a free trial or book a demo to walk the flow.
Protect the grade, and you protect the machine
HVI gives every operator a grader-specific inspection, routes flagged defects straight to a work order with photos attached, fires PM on real meter hours, and keeps one cost-tracked history per machine. Blade, circle, drawbar, and articulation get caught on the walkaround — as a cheap shim, not a scrapped grade or a five-figure rebuild. Live in under two weeks.
