I have designed a new adjuster plate that bolts right over the present New Holland two point hold down clip. It takes seconds to install the device and enables the operator to adjust the cutting tolerance between the knife and hold down in seconds. A complete 30ft. header can be adjusted in 15 to 20 minutes to a tollerance of "1" thousands of an inch, instead of a day, taking and putting shims in and out! Any one interestedIJIJIJ I call the device, PRECISION ADJUSTERS.
