About · JCB 85ZOverview
The JCB 85Z is an 8.5-tonne zero-tail-swing mini-excavator, positioning it at the upper end of the compact excavator class where it bridges the gap between conventional midi machines and larger tracked excavators. Its zero-tail-swing configuration keeps the counterweight within the track width, allowing safe operation in confined urban and roadside environments without risk of tail strike. The machine is powered by a turbocharged diesel engine meeting current Tier 4 Final or Stage V emissions standards, paired with a hydraulic system sized for high-flow auxiliary attachments. As a JCB product it carries the manufacturer's established European dealer and parts network.
Typical applicationsWhere this machine is used
The 85Z is suited to urban groundworks, utility trenching, drainage installation, and foundation excavation where site access or working clearance is restricted. Its weight class provides the breakout force needed for harder ground conditions and deeper trenches while remaining within the limits of standard low-loader transport. The zero-tail-swing geometry makes it a practical choice for pavement-level and roadside work, basement projects, and any task requiring operation close to walls, fencing, or passing traffic.
Used-market inspectionWhat to check before buying
Before purchasing an 85Z or any machine in this weight class, inspect the undercarriage carefully: check track tension, rubber or steel track wear, roller and sprocket condition, and any cracking or link damage, as undercarriage refurbishment represents a significant cost in this class. Examine the boom, dipper, and bucket pins and bushings for play, and verify that grease nipples and lubrication points have been maintained regularly. Review the service history for evidence of scheduled oil and filter changes, and confirm that any hydraulic attachment circuits have been flushed and serviced according to manufacturer intervals. Check the cab for moisture ingress, seat and control wear consistent with stated hours, and confirm that the instrument cluster displays no active fault codes. On machines with a quick-hitch, confirm the locking mechanism operates correctly and that the hitch matches the attachment inventory being offered. Machines with comprehensive service records, low hours relative to their year of manufacture, factory-fitted air conditioning, and a matched hydraulic attachment set consistently sit above the class average, while high hours, missing documentation, or worn undercarriage position a machine below market.
Current marketPrice position
Within the 8 to 9-tonne zero-tail-swing segment the JCB 85Z is routinely cross-shopped against the Volvo ECR88D, the Kubota KX080-4, and the Takeuchi TB285. Compared with the Kubota KX080-4, the JCB tends to offer a larger cab environment and a more prominent dealer footprint across Western Europe. Against the Volvo ECR88D, buyers often weigh JCB's parts availability and resale familiarity in regional markets. The Takeuchi TB285 competes closely on operating weight and hydraulic performance, making brand preference and local support the deciding factors. Within the class, the attributes that move any individual machine through its price band are recorded operating hours, service history documentation, cab specification and air-conditioning fitment, the presence of a quick-hitch system, the number and type of attachments included, blade configuration, and overall undercarriage condition including track and roller wear.
