Summer vine trimming is important in maintaining a healthy vineyard. The lower vine shoots are trimmed at an angle to increase spray penetration into the canopy. It can also minimise cane breakage from machinery tyres. If the vineyard is machine harvested, a neatly trimmed vine is easier to harvest and puts less leaf in the load. We use a trimmer mounted to the front of a Kubota RTV with a 1.2 meter cutter bar covering a large range of cutting angles.
