Why will my skid steer not move or start?
First describe whether the skid steer will not crank, runs but will not travel, or has a lift/tilt function disabled. Record the exact warning. A safety-interlock message is not permission to bypass the system to finish a job.
Application & limits
Skid-steer/compact-loader booking information. Bobcat S650 sources illustrate safety equipment only; no model-specific interlock diagnostic is generalized.
What the symptom or code tells you
Bobcat’s S650 specification lists the BICS interlock, seat bar and lift-arm support as safety equipment. It establishes that these are safety features, not a diagnostic explanation for every no-move event.
This page is operator-information and booking guidance. No switch, sensor, restraint or controller is diagnosed here. Interlock design and normal operating conditions vary by model, serial number and control option.
Information to send
Use details already available from the normal operator position or your records. Do not run a test or approach a hazard to collect them.
- Make/model/serial from fleet records or an existing safe data-plate photo.
- Exact code or a display photo already available from the normal operator position.
- Whether starting, travel, lift, tilt or an attachment is affected.
- Attachment/load position, ground conditions and safe service access.
What the mechanic assesses
Use only the normal checks described in your own operator manual. If the warning remains or the machine behaves unexpectedly, stop affected operation and request service. The mechanic needs the serial-matched operating and service information before discussing tests or parts. Include any recent control, battery or restraint work.
Prepare a repair request
Text the machine or vehicle, exact symptom and location. We confirm scope, safe access, parts needs, pricing and availability before a visit.
