Bobcat & Plant Repairs
Electrical, hydraulic and mechanical repairs on site. Faults are tested and proven before parts are condemned.
Explore plant support →Mobile Bobcat engineer based in Grays, Essex, covering Essex, London and the South East. 14 years working within a Bobcat dealership environment, Bobcat trained, and formerly a technical support lead engineer. Hawes & Son brings serious diagnostic and repair experience directly to your machine — without the workshop runaround.

If a machine has stopped, lost drive, developed a serious fault or downtime is costing you money, call direct. Have the model, serial number, hours and location ready if possible.
Bobcat is the main focus. Diagnostics, repairs, servicing and warranty support are backed by proper testing, clear reporting and real field experience. Automotive support is also available.

Diagnostic capability →Emissions fault diagnosis and forced/parked regeneration on supported Bobcat, CAT and automotive systems — after the underlying cause has been checked.
Book diagnostics →Scheduled services, inspections, fluids, filters and defect reporting carried out at your site or yard.
Service support →Bobcat warranty customers can contact Hawes & Son directly. We can assess the fault and handle eligible authorised warranty work subject to the applicable approval route.
Warranty customers →Competitive parts pricing on genuine Bobcat components and quality aftermarket alternatives. We can price both routes where suitable so you can compare the options before ordering.
Request parts pricing →Mobile diagnostics, servicing, DPF work and mechanical repairs where the job is suitable for field attendance, including specialist fleet vehicles such as ice cream vans.
Automotive support →Hawes & Son uses professional Autel diagnostic equipment for supported automotive systems. That gives us access to far more than basic fault-code reading — live data, system scans, active tests, service functions and emissions diagnostics can all form part of the fault-finding process where the vehicle supports them.
We use the computer alongside hands-on electrical and mechanical testing, so the aim is to prove the fault before parts are replaced.
This is a selected snapshot of work carried out by Hawes & Son — not every machine, customer or job is shown. The gallery will grow with useful examples that show the type of diagnostics, repairs, servicing and site support we actually carry out.

Need support on your machine?
BOBCAT • ON-SITE DIAGNOSTICSOn-site Bobcat diagnostic work using the laptop and machine systems at the customer location — fault finding where the machine is working rather than automatically sending it away.
MOBILE • SITE SUPPORTOur service van and equipment go straight to the customer site, keeping the work practical and reducing unnecessary machine movement.
PLANT • FIELD ENGINEERINGPlant support at customer yards and working locations, with the van set up to carry the tools, fluids and diagnostic equipment needed on the job.
BOBCAT • MOBILE SERVICINGMobile plant servicing with the van, tools and service equipment brought directly to the machine at the customer location.
SERVICING • PARTS & FLUIDSFilters, fluids and service parts organised on site so scheduled maintenance can be completed efficiently in the field.
PLANT • CUSTOMER SITESelected examples from working yards and sites, showing the mobile setup used for servicing, repairs and fault finding.
SPECIALIST FLEET • AUTOMOTIVEAlongside plant work, Hawes & Son supports selected specialist and unusual fleet vehicles where mobile engineering support is suitable.
FLEET • SELECTED WORKReal examples of the varied fleet and automotive work carried out alongside the main Bobcat and plant engineering focus.
GRID FIT • ELECTRICAL DIAGNOSTICSOn-site fault finding for Grid Fit. Testing traced the electrical issue to a plug where incorrect-size terminals had previously been fitted, causing a connection problem. A good example of why proper testing comes before replacing parts.
EDEN ENERGY • ELECTRICAL DIAGNOSTICSAfter several previous attempts to resolve an electrical fault, Hawes & Son was called in. Structured Bobcat electrical diagnosis traced the issue and returned the machine to operation after around three months out of service.
BOBCAT • TRACK MOTOR REPAIRThis Bobcat T86 was immobilised by a failed track motor. The track was removed, the drive assembly stripped down on site and the failed unit replaced before the hydraulic system and drive operation were checked and the machine returned to service. A proper field repair carried out where the machine was working.
SPECIALIST FLEET SUPPORTHawes & Son also supports specialist fleet vehicles, including ice cream vans. Mobile diagnostics, DPF and emissions work, electrical and mechanical repairs, servicing and fault finding are available at your site or yard where the job is suitable for mobile attendance.
Especially useful for vehicles that spend long periods idling, where DPF and emissions faults can become a recurring problem.
