At the last Agritechnica, Kverneland introduced its new folding power harrow combination for highcapacity applications. Boasting the firm’s latest CX-II disc coulters in combination with press wheels, we trialled the seeding outfit in the field — to find out what’s new on an otherwise proven machine
The NG-H F30 power harrow and the new CX-II disc drill make for a good pairing. The test machine used the well-balanced format of a frontmounted hopper with a coulter bar piggybacked onto the power harrow. Kverneland offers this set-up in four different working widths — 4.0m, 4.5m, 5.0m and 6.0m — the latter being the one we used to get stuck into work for our driving impression.
In the past, Kverneland lacked a folding power harrow in the sub-300hp range, a gap the F30 now fills. The machine sports a self-supporting gear trough, replacing a beefy and heavy frame. The profiled bed is built from 6mm steel plate and is formed by two units — a trough and its bolted-on lid. The base of the bed is double-welded, which should give it extra strength and a longer life, according to Kverneland.
The gears that drive the tines are carried on taper bearings, the housings of which are welded to the trough. These chunky components are made to suit high-horsepower applications. There is a 95mm clear space between the rotors and the base of the bed, designed to aid a smoother material flow through the sharp-angled quick-fit tines. These can also be fixed at a less aggressive angle, and that’s how we had the outfit set up for our test, working behind a plough and press — conditions that admittedly did not excessively challenge the system.
