Skid Steer Maintenance Checklist: Daily to 1,000-Hour Service

Skid steers live a rough life. They dig, grade, push snow, carry pallets, run augers and brush cutters, and get parked wherever the job ends. Most of the expensive failures on them (worn pins, cooked hydraulics, a seized chaincase, a clogged radiator that overheats the engine) start as something a five-minute daily check would have caught.

The checklists that rank for this topic agree on the basics and then disagree on the intervals, often within the same page. This guide gives you a daily checklist you can actually use, a typical hour-based schedule, two real manufacturer schedules side by side so you can see how much they differ, and a worked example of how the 12-month limits change things for machines that don’t run many hours.

How skid steer service intervals work

Three rules hold for nearly every skid steer and compact track loader:

• Intervals run on the hour meter. It counts every hour the engine runs, idle included. A machine that idles between loads all day is using up service hours.
• The tiers are cumulative. At 500 hours you do the 500-hour list plus the 250, 50, and daily lists, so plan the big services as the small ones with extra work on top.
• Many intervals carry a calendar limit. Bobcat’s schedules read “every 500 hours or every 12 months,” and coolant is often on a fixed number of months. Fluids age whether the machine runs or not.

The intervals below are typical ranges, not universal numbers. Your operator’s manual (or the service decal on the machine) sets the real ones, and warranty claims are judged against that manual.

Daily skid steer checklist (before you start the engine)

Do this with the machine on level ground, the bucket flat on the ground, the parking brake set, and the engine off. Those are the same three steps NIOSH’s skid-steer loader safety alert tells operators to take before leaving the seat. If the lift arms have to be up to reach anything, engage the lift-arm support device first.

1. Engine oil: check the dipstick and top up with the grade in the manual.
2. Coolant: check the level only when the engine is cold.
3. Hydraulic oil: check the sight glass with the bucket down and the machine in the position the manual specifies.
4. Air filter: look at the restriction indicator. Replace the element when the indicator calls for it, not on a guess.
5. Radiator and oil cooler: blow out or brush off packed debris. Leaves, chaff, and sawdust overheat skid steers faster than almost anything else.
6. Fuel filter / water separator: drain any water.
7. Grease: lift arm pivots, lift and tilt cylinder pins, and the quick-attach (Bob-Tach, Quik-Tatch, or whatever your brand calls it), including the wedges or locking pins.
8. Walkaround: fresh leaks, chafed hydraulic hoses, cracked welds, loose or missing pins and retainers.
9. Tires or tracks: cuts, pressure, and loose wheel nuts on wheeled machines; packed mud, damaged lugs, and visible sag on track loaders.
10. Safety systems: seat belt condition, seat bar, and control interlocks. With the seat bar raised, the lift and tilt functions should not work. Test the horn, lights, and backup alarm.
11. Hour meter: write down the reading and anything you found.

The whole list takes 10 minutes once it is a habit. The last step takes 10 seconds and is the one that gets skipped.

Skid steer maintenance checklist by hours

This is the shape of a typical schedule for a diesel skid steer or compact track loader in normal duty. Use it to set up your tracking, then replace each interval with the number from your manual.

Two real schedules, side by side

Generic tables hide how much manufacturers differ. Here is Deere’s maintenance planner for the 320G and 324G skid steers and 325G track loader next to the service schedule in Bobcat’s S70 Operation & Maintenance Manual, a compact skid steer.

Three things stand out:

1. The engine oil interval differs by more than 3x. If you run both brands and use one number for the whole yard, one machine is getting its oil changed far too often or far too rarely.
2. Bobcat puts a 12-month limit on most service tiers. The Deere planner lists hours, plus fluid analysis kits at 500 hours with a footnote that intervals may need adjusting based on the results. Check your Deere manual for any calendar limits.
3. Track loaders add their own items. Deere’s 325G gets a track tension check every 50 hours and an initial drain and refill of the hydrostatic planetary gear case oil at 50 hours, neither of which applies to the wheeled 320G.

Bobcat’s manual also says filter and oil life can be shorter in high dust, extreme temperatures, or when fuel comes from uncontrolled storage tanks. That last one is common on farms and small job sites, and it is a good reason to drain the water separator every day.

Worked example: three machines, three kinds of year

An hour-based checklist reads the same for every owner. What it means on the calendar doesn’t. Take three skid steers on the Bobcat S70 intervals above (engine oil every 150 hours or 12 months, hydraulic fluid every 1,000 hours or 12 months):

On this machine, the hydraulic fluid is a calendar item for all three owners. The farm machine never reaches 150 hours between oil changes, so if its owner tracks hours only, the oil sits in the engine for 18 months. The contractor’s six oil changes a year mean filters should be on the shelf, not ordered when the reminder fires.

Run the same three machines on Deere’s 500-hour oil interval and the contractor drops to about two changes a year, while the farm machine would take five years to reach 500 hours. That is why low-hour owners need either the manual’s calendar limit or an annual service habit, and why you track each interval as “hours or months, whichever comes first.”

Wheeled skid steer vs compact track loader

Most of the checklist is shared. The undercarriage is where it splits.

Wheeled skid steers

• Tire pressure daily. Bobcat’s S70 manual says to inflate to the maximum pressure shown on the tire sidewall. Uneven pressure makes the machine pull and wears tires on one side.
• Wheel nut torque. Check daily for the first 50 hours, then every 50. Wheel nuts on a machine that skids to turn all day do work loose.
• Chaincase oil. Chain-drive machines have an oil bath on each side. Check the level on schedule and look for metal or a milky color when you change it.

Compact track loaders

• Track tension. Too loose and the track can come off; too tight and it wears rollers, idlers, and drive motors. Measure it the way the manual describes, usually as sag at a specific point.
• Undercarriage cleaning. Mud, clay, and rocks packed into the rollers freeze or harden overnight and load the drive. Clean it out at the end of the day, not the next morning.
• Final drive or planetary oil. Track loaders typically have their own gear case oil with an early break-in change. Check the manual for both intervals.
• Wear parts. Inspect rollers, idlers, and drive sprockets for flat spots, leaks, and hooked teeth. Their wear sets the price of the next undercarriage job.

When to shorten the intervals

Published intervals assume general conditions. Plan on shorter ones for:

• Dust: demolition, dry grading, and feedlots load air filters and radiators. Go by the restriction indicator and clean the cooler daily or more.
• High-flow attachments: mulchers, cold planers, and trenchers heat the hydraulic oil hard. Hydraulic oil analysis tells you how much life is left.
• Debris: forestry and leaf cleanup pack the engine compartment, which is both an overheating risk and a fire risk. Blow it out at the end of every shift.
• Water and mud: grease more often; standing water around pins and tracks works its way into joints.
• Uncontrolled fuel storage: drain the water separator daily and change fuel filters early.

Keeping records so the checklist actually happens

A checklist on a clipboard tells you what to do today. It doesn’t tell you that the hydraulic filter is 80 hours overdue. A few habits close that gap:

• Record the hour meter at least weekly. Every machine, one number, same day each week. Every interval on the checklist hangs off that number.
• Log each service against hours and date. What was done, parts and fluids used, cost, and who did it. “Changed oil” without the hour reading is half a record.
• Track each interval separately. The 150-hour oil change and the 1,000-hour hydraulic service are separate reminders with separate last-done readings.
• Keep receipts and oil analysis reports with the entry. They answer warranty questions and help when you sell the machine.
• Record what the daily check found. A machine that needs a quart of hydraulic oil every week has a leak, and only the log shows the pattern.

If you want to start in Excel, our free preventive maintenance schedule template has columns for hour and date intervals, and the fleet maintenance spreadsheet handles service history and costs. If the skid steer shares the yard with an excavator or a tractor, the heavy equipment maintenance schedule and tractor maintenance schedule guides use the same hour-based approach. Once several people are logging work on several machines, it is worth comparing a spreadsheet against software.

Common mistakes and when to call a professional

• Skipping grease on busy days. Dry pins and bushings wear oval fast, and a sloppy quick-attach is a safety problem as well as a repair bill.
• Bypassing the seat bar or interlocks. NIOSH’s alert is blunt: never modify or bypass safety devices. If an interlock is faulty, fix it before the machine goes back to work.
• Working under raised lift arms without the support device. Hydraulics can bleed down or a hose can fail. Use the lift-arm support every time.
• Missing the first-50-hour services. On a new or rebuilt machine, the break-in oil and filter changes are some of the most important on the chart.
• Mixing fluids. Hydraulic, hydrostatic, and chaincase oils have specs. The wrong one can damage seals and pumps.

Daily checks, greasing, fluid top-ups, and filter changes are well within reach of a careful owner. Call a qualified mechanic or your dealer for hydraulic leaks under pressure (fluid can inject through skin, so never feel for a leak with your hand), interlock or control faults, drive motor and chaincase repairs, valve adjustments, track and undercarriage replacement, and any warning light or fault code you can’t explain. Before any hands-on work, lower the bucket or engage the lift-arm support, set the parking brake, shut the engine off, and remove the key.
