Model / Serial Number Guide


Your tag will be a small white sticker, no bigger than a business card, normally found under the seat, near the battery box.

Model Numbers are 6 digits long and usually begin with the number "8" or "9".

For engine and hydro pump parts not listed on this site, look for a printed tag on the engine and give us a call - we're here to help!

With hydro pumps, common parts (such as cooling fans) can be changed mid-line and differ wildly between units in the same series.

For accurate identification of hydro pumps, look for the unit's serial number. This will be printed on a sticker on the pump, or stamped on the unit's casing for older style pumps.


Most often, these tags are riveted to the machine. However, unlike modern units, the serial number is more important than the model number, and can almost serve as a blueprint of your Gravely unit. When in doubt, find the serial number first and give us a call!
