Kubota RC54-71B, RC60-71B Common Problems This Manual Covers
Streaking or strips of uncut grass
Streaking usually comes from worn blades, low spindle speed, or ground speed set too fast for the conditions. The troubleshooting section lists streaking causes and the checks to make.
Manual Section: Troubleshooting p. 24Uneven cut height
A deck that cuts unevenly is often out of level because the gauge wheels or connecting rods are set wrong. The adjustments section covers the front link and connecting rod turnbuckles that level the deck.
Manual Section: Mower Adjustments p. 16Excessive vibration
Heavy vibration points to worn, bent, or unbalanced blades or loose blade capscrews. The maintenance checklist includes blade wear checks and confirming the blade capscrews are tight.
Manual Section: Maintenance p. 20Drive belt slipping
A belt that slips under load leaves the blades short of full cutting speed and streaks the grass. The troubleshooting section covers belt slipping among the cutting faults.
Manual Section: Troubleshooting p. 24Gear box oil low or leaking
A low or contaminated gear box can whine or fail if the oil is not checked and changed on schedule. The maintenance section covers the gear box oil check, oil change, and oil seal replacement.
Manual Section: Maintenance p. 20Rust and belt set from winter storage
Left dirty and under belt tension over winter, the deck can seize pulleys and take a set in the belt. The storage section covers slackening the tensioner and cleaning the deck before layup.
