7.0 ADJUSTMENTS
Before performing any adjustments first shift to park, disengage PTO, lower machine to
ground, relieve hydraulic pressure, stop engine, remove ignition key, and wait for all
moving parts to stop before adjusting.
7.1 Leveling
To obtain optimal performance of the defoliator, the machine
must be level from left to right while defoliating. Critical to main-
taining machine level is rear strut style and location. Selecting a
strut style and tire location that do not run in previous tractor and
sprayer tracks will greatly help the ease of maintaining field level
and increase defoliation quality. Rear struts design is flexible so
that they can be located for best performance. Because of your
Amity defoliator
’ s unique and low maintenance gearbox drive sys-
tem, the right side of the defoliator is inherently heavier which will affect side to side level. Amity
defoliator
’ s come with weights mounted on the left side to counteract this; however depending on
the options equipped an additional 100 - 300 lbs. (45 - 135 kg) can be added to the weight bracket on
the front left corner to achieve a perfectly balanced machine. Instead of the preferred method add-
ing weights, you may also adjust air pressure in your tires. Starting with all tires at the recommend-
ed pressure (see Section 3.0 Specifications) adjust pressure up on the right tires and proportionally
down on the left tires until the distance from bottom of the axle tube to the floor is equal on both
sides which indicates the static loaded radius of the tires is the same. (Not recommended for defoli-
ators with optional 4 struts) Once the weight bias on your Amity defoliator is accounted for, check
flail distances from a flat and level floor. If additional adjustment is required to level the defoliator
please follow the procedures laid out below:
7.1.1 Manual: (Rear struts equipped with ratchet jacks for adjustment.
1. Move the defoliator on to a flat and level floor for accurate measurements.
2. Lower the defoliator front hitch cylinders to approximate operating height.
3. Check tire pressure to ensure both sides are correctly inflated.
4. Measure the distance between the drum #3 flails and ground, or rear frame tube and ground on
the very outside of the left and right hand sides of the defoliator
5. To level the defoliator, choose the side which is closest to the desired height. Then adjust the
rachet jack on the opposite side until the machine is level.
6. Future height adjustments should be made in equal amounts on both struts to maintain level.
