Kubota B6100HST, B7100HST Common Problems This Manual Covers
Loud whine and power loss under load
A B7100HST that whines and loses pushing power on inclines usually has a tired hydrostatic drive, low fluid, or a clogged suction screen. The troubleshooting chapter helps isolate the tractor and drive faults.
Manual Section: Troubleshooting p. 61Hard starting in cold weather
These diesels can be stubborn to start cold if the preheat, battery, or fuel supply is off. The operating instructions cover correct engine starting including glow plug preheating time.
Manual Section: Operating Instructions p. 27Excessive steering wheel play
Loose steering with too much free play is common wear on the B6100 and B7100 front end. The adjustments section sets steering wheel play back within the specified range.
Manual Section: Adjustments p. 55Uneven or weak braking
Brakes that grab unevenly between left and right, or feel weak, need adjustment on these internal brake systems. The adjustments section covers setting brake pedal play correctly.
Manual Section: Adjustments p. 55Weak hydraulic lift response
Slow or weak lift often comes from a neglected transmission and hydraulic oil service. The check and maintenance section covers the transmission oil, filter cartridge, and suction screen intervals.
Manual Section: Check and Maintenance p. 37Front axle and steering wear
Play in the tie rod ends, drag link, or pivot pin shows up as sloppy handling. The check and maintenance section covers greasing these points and the front axle service items.
