Snow Blower Service and Shear Pin Log

A free printable snow blower log: a pre-season check for each winter, every shear pin break and what was hit, and scraper bar, skid shoe, belt and engine work.

First page of the Snow Blower Service and Shear Pin Log — See which winter the scraper bar went and how many shear pins the auger has eaten. The part numbers sit at the top, so the right shear pin is bought, not a bolt that happens to fit the hole.

What this sheet is for

See which winter the scraper bar went and how many shear pins the auger has eaten. The part numbers sit at the top, so the right shear pin is bought, not a bolt that happens to fit the hole.

Who it is for

Households, caretakers and grounds staff with a single or two-stage snow blower, petrol or battery.

How to use it

  1. Fill the specification block once from the handbook and the parts list, including where the spare shear pins are kept.
  2. Before the first snow, work down one column of the pre-season check and write the year at the top.
  3. Each time a pin breaks, write what was hit, how many went and how many spares are left.
  4. Log scraper bar, skid shoe, belt and engine work underneath, with the part numbers and the cost.

Ruled lines: Notes — what the machine cleared badly, odd noises, parts to order before winter

Questions

Why does the sheet ask whether the right pin was fitted?

Because a shear pin is meant to break before the gearbox does. An ordinary bolt of the same size will not, and the next stone in the auger can wreck the drive. The column is a reminder to fit the maker's listed part every time.

Where are the oil grade, plug gap and service interval?

In the blanks at the top, for you to copy from your own handbook. They differ from one machine and engine to the next, so a printed figure would be a guess on your behalf.

Does it work for a battery snow blower?

Yes. Leave the oil and plug lines blank and use the rest as written; the auger, shear pins, scraper bar and belts wear the same way whatever drives them.
