Kubota BX2816 Common Problems This Manual Covers
Auger stops feeding on one side
When one side of the auger stops feeding snow while the other keeps working, a broken shear bolt is the usual cause. The Maintenance section covers shearbolts and their replacement, including the shear bolt torque of 9 lbs-ft.
Manual Section: Maintenance p. 24Snow and ice pack in the housing
Wet, heavy snow can pack the auger housing and leave the machine sluggish or non-spinning until it is cleared. The Operation section covers snow removal methods and engine speed so you can keep the blower throwing cleanly.
Manual Section: Operation p. 20Drive chain runs loose
A loose or throwing drive chain reduces power to the auger and can jump the sprockets. The Maintenance section covers drive chain adjustment, with a deflection target of 1/16 inch to 1/8 inch.
Manual Section: Maintenance p. 24Weak or uneven snow throw
If the drive side runs but snow output is weak or uneven, a partial shear bolt failure or material packed around the flights is often to blame. The Troubleshooting section helps isolate the cause.
Manual Section: Troubleshooting p. 28Scraping or uneven ground clearance
Skid shoes set wrong will scrape a paved surface or dig into gravel. The Operation section covers skid shoe adjustment so you can set the correct clearance for your surface.
Manual Section: Operation p. 20Dry pivots make the auger hard to turn
Ice or a lack of grease in the drive and pivot points can make the auger and impeller hard to turn by hand. The Maintenance section covers the lubrication schedule and auger lubrication interval.
