A best-selling wheeled skid steer where the hydrostatic drive, chaincase, and Bob-Tach reveal a hard rental life.
The S650 is one of the most common skid steers in rental fleets, so hard use is the norm. The drivetrain and hydraulics carry the value, and the chaincase and attachment mount show how it was treated.
Worn drive motors cause pulling and creep.
CHECK Drive straight on level ground and check for creep with controls centered.
Stretched chains and low chaincase oil cause slop and failures.
CHECK Check chaincase oil and feel for drivetrain slack.
The attachment mount and wedges wear with heavy use.
CHECK Inspect the Bob-Tach and confirm attachments lock solidly.
Lift and aux hydraulics weaken and drift.
CHECK Check lift drift and test auxiliary hydraulics.
Tire and engine condition follow use.
CHECK Check tire wear and engine blowby.
