Before the first spring job, walk through every attachment. What winter storage does to hydraulic seals, pins, and cutting edges costs you more to fix mid-season than to catch now.
March and early April in most of Canada is the window between winter shutdown and the first billable day of the season. That window is short, and it's the right time to pull attachments out of storage and go through them properly — not when you're already behind on a job.
This guide walks through the inspection systematically: hydraulic couplers first, then mechanical wear points, then lubrication, then the machine's hydraulic system itself. It also covers the specific damage patterns that show up after a Canadian winter, which are different from what you'd see after storage in a milder climate.
Canadian winters are harder on equipment than many operators account for. Several mechanisms cause damage specifically during the idle months:
Start with the couplers — they're the most contamination-sensitive part of any hydraulic attachment circuit, and contamination introduced here goes straight into the machine's hydraulic system.
Less common on newer attachments but still found on older equipment. Check thread engagement, replace the O-ring if it shows any hardening or cracking, and ensure the coupler bodies aren't cross-threaded from last season's rushed coupling.
Every pivot point on an attachment has a pin and bushing. These wear during operation and degrade during storage from the freeze-thaw mechanism described above. The inspection is straightforward but requires physically moving the components.
If you don't have a wear spec from the attachment manufacturer, the rule of thumb for most skid steer attachment pins is: more than 1–2 mm of measurable radial play in a critical pivot (cylinder anchor, quick attach pin) is worth replacing before the season starts. Letting it run to failure mid-season costs more in unplanned downtime than the pin and bushings.
Cutting edges on buckets, blades, and grading attachments wear during operation and are one of the highest-value inspection items at spring startup. A bucket running with worn-past-spec cutting edges is less efficient, digs poorly, and risks damaging the bucket floor when the edge wears through completely.
Rock grapples, brush grapples, and industrial grapples all have tines (the curved clamping fingers) that take substantial abuse and are worth checking carefully before a new season.
The quick attach is the most-used mechanical interface on the machine. Bob-Tach, SSQA (Skid Steer Quick Attach), and other systems all require inspection at the attachment side — the pins, hooks, and locking surfaces that engage the carrier plate.
Every attachment has grease points. Spring is the time to grease them all, and generously — the goal is to displace any moisture that has worked into the bearing surfaces over winter, not just a maintenance top-up.
| Attachment Type | Key Grease Points | Notes |
|---|---|---|
| Bucket | Quick attach plate hooks, any pivot pins if tilt-equipped | Simple attachments still have grease zerks on tilt cylinders if equipped |
| Auger | Drive coupling, auger-to-drive pin connection, gearbox input (if serviceable), bit connection | Check gearbox oil level separately from grease points |
| Rock/Brush Grapple | All tine pivot pins, cylinder pin both ends, frame pivots | Multi-tine grapples have many zerks — go through all of them |
| Hydraulic Breaker | Chisel retention pins, mounting bracket pins, any pivot on mounting frame | Breaker body lubrication per manufacturer spec — not all take standard grease |
| Tilt Attachment / Angle Blade | Tilt cylinder pins both ends, pivot tube, angle cylinder pins | Multiple cylinders = multiple greasing points; do all of them |
| Power Rake / Soil Conditioner | Rotor bearing flanges (both ends), gearbox input shaft, drum pivot mounts | Bearing flanges are often dusty and overlooked — clean before greasing so you can see the zerk |
| Brush Cutter / Flail Mower | Rotor bearing flanges, deck pivot pins, belt tensioner pivot | Inspect belts and blade bolts while greasing |
| Land Plane / Box Blade | Cutting edge pivot if adjustable, scarifier shank pivots | Minimal but still important — seized scarifier shanks are common after winter storage |
Use multi-purpose lithium grease or a moly-fortified grease for most attachment pivot points. The brand matters less than actually using enough — pump grease until fresh grease is pushing out past the old grease at each zerk. That's the indicator you've actually displaced old grease and moisture from the bearing surface.
The machine's hydraulic fluid affects every attachment you run. Spring is a critical time to assess fluid condition, because cold-weather storage creates specific contamination risks that mid-season maintenance doesn't address as thoroughly.
Most skid steer manufacturers specify a hydraulic fluid change interval of 1,000–2,000 hours or annually, whichever comes first. If you didn't change the fluid in fall before storage, spring startup is the right time. Cold weather doesn't extend fluid life — in some ways it accelerates degradation through the condensation mechanism.
After a winter layup, don't run attachments at full load immediately on startup. Let the machine idle for at least 5–10 minutes to allow hydraulic fluid to warm and circulate through the system. Cold fluid is viscous and doesn't lubricate pump internals adequately at full load from a cold start. Then operate the attachment at light load for the first 15–20 minutes of the first day. This is especially important below 0°C ambient.
Some damage patterns show up more often after Canadian winters than after storage in milder climates:
Hydraulic hose outer jacket can crack at sustained temperatures below -35°C, particularly at crimped ends and tight bend points. Inspect every hose on the attachment by flexing it slightly at suspect areas. A crack in the outer jacket doesn't always mean the inner tube is compromised, but a hose with a cracked jacket at the crimp should be replaced before operating — the inner tube is under stress at that point and will fail under pressure.
A cylinder stored with exposed rod that developed surface rust over winter will feel stiff to extend and will likely weep past the rod seal immediately. Don't force a seized cylinder. Light surface rust on the rod can sometimes be cleaned with fine (2000-grit) wet/dry abrasive paper and oil, but any pitting deeper than surface oxidation means the rod seal will be destroyed on extension — the cylinder needs a rod replacement or rebuild.
Auger drives, sweeper housings, and box-enclosed attachment spaces get used as nesting sites. Before starting any enclosed hydraulic motor or drive system in spring, visually inspect the housing for nesting material. A motor packed with mouse nesting material will overheat immediately. More concerning: rodents chew hydraulic hoses. Inspect hoses in any enclosed area for bite marks or gnawing damage.
The quick attach plate surface that contacts the machine carrier is a bare-metal wear surface that often develops surface rust over winter, especially with outdoor or unheated storage. Light surface rust cleans off with a wire brush and doesn't affect function. But significant rust buildup on the hook and pin contact surfaces affects engagement geometry — clean before you connect the attachment and check that engagement is solid before loading.
