For any side arm user involved in both hedge and verge mowing, the roller on the back of the cutting head is essential for maintaining an even cutting height when mowing verges, although it can be a nuisance for hedge work. To overcome this, BOMFORD has introduced a new version of the well proven PRO-CUT cutting head, which incorporates a retractable hydraulic roller. For verge mowing on rough ground, the roller can be quickly lowered whilst on the move in order to raise the cutting height and so avoid the flails scalping the verge. Not only does this result in a neat finish but more importantly for the operator, it avoids excessive wear on the flails. The ability to be able to completely retract the roller whilst hedge cutting, will result in a cleaner, neater finish without any interference caused by the roller running on the hedge. The retraction assembly consists of a single hydraulic ram acting on a connecting shaft that is contained within the cowl support bar for added protection. The roller itself is protected and supported by the replaceable skid assembly and the retraction linkage system also incorporates an adjustable link to ensure that the roller can be maintained level
