Abstract
A mower comprising a vehicle, a plurality of cutting assemblies, and an automatic height of cut control system is described. In some aspects, the automatic height of cut control system is configured to automatically change the height of cut for the plurality of cutting assemblies while maintaining the attitude of each cutting blade as the blade moves from a first height of cut to a second height of cut. In some aspects, the cutting assemblies include a variable-length member linked to a four-bar linkage configured to cause a change in the height of cut in response to a change in length of the variable-length member.
