Hayter scarifier in the workshop for service and repair this week. Scarifing is generally a spring or annual or even less frequent task and consequently if using pump fuel that is left in the machine for long periods festering away and damaging all the components of the fuel system the machine will be rendered useless and sometimes beyond economical repair. We are always available to help and advise what may be best for you and your machine. Call 07837 186830 or 01206 729509.
AI Overview A dethatcher gently rakes surface debris, a scarifier aggressively cuts deep into turf to remove heavy thatch, a verticutter slices grass shoots to thin the canopy, and an aerator punctures soil to fix compaction. For more details on these machines, you can read the VonHaus lawn guide.
