Saphir 7 was introduced in 2002 to re-<br />
D place the DKA range. 94% of all<br />
owners surveyed say that they would buy<br />
the machine again, which clearly reflects<br />
a high consumer satisfaction, which is<br />
mainly attributed to the <strong>seed</strong> hopper,<br />
whose capacity is high for a mechanical<br />
drill but not too high. Another plus is its<br />
convenient platform that allows easy filling.<br />
The hopper also provides for<br />
straightforward emptying, but the inserts<br />
that are fitted for rape<strong>seed</strong> drilling to reduce<br />
the amount of remaining <strong>seed</strong>s do<br />
not earn good marks.<br />
Calibration is controlled from the cab<br />
computer, which is straightforward and<br />

Saphir 7 (cultivator-mounted mechanical drill)<br />
Year of manufacture: from 2002<br />
Work width: 2.5/3.0 m and 4.0 m<br />
Hopper capacity: 800 l or 1,100 l on<br />
3 m version; 1,050 l on 4 m version Saphir 7 gains its<br />
popularity from<br />
Solitair 9<br />
(linkage/cultivator-mounted pneumatic drill)<br />
Year of manufacture: from 1998<br />
Work width: 3.0 m – 6.0 m<br />
Hopper capacity: 1,100 l on 3 m/4 m<br />
version (extended to 2,300 l)<br />
Solitair 9 scored sweepingly good<br />
marks. Even the manual was regarded<br />
as “excellent“. The same applies to quality<br />
convenient, whereas conversion to small<br />
<strong>seed</strong>s is more cumbersome. Most machines<br />
surveyed rely on double disc coulters<br />
followed by depth wheels. Lemken<br />
says there is no need for a coulter pressure<br />
setting system and none for tines. Depth<br />
control is <strong>accurate</strong> and so is <strong>seed</strong> <strong>placement</strong>.<br />
Wet and heavy soils present a problem<br />
to the system and some owners would<br />
of build. As a result, repairs are rare despite<br />
covering high acreages every season.<br />
Although the hoppers feature excellent<br />
capacities, lift requirement is considered<br />
low thanks to the hopper being located<br />
closer to the tractor than on the mechanical<br />
version. The excellent steps provide<br />
optimum access. Praise went to the good<br />
lid as well as to straightforward emptying<br />
and cleaning. Machine layout was considered<br />
good despite the big hopper. All<br />
owners praised the calibration testing and<br />
<strong>seed</strong> rate setting system, which is from the<br />
Outstanding features on Solitair 9 are hopper, <strong>seed</strong> <strong>placement</strong> and quality of<br />

with such conditions.<br />
Build quality is excellent whereas reliability<br />
and fail-safe operation is average.<br />
The plastic coulter covers are too flimsy<br />
while the electric system occasionally<br />
failed. The spike wheel sticks out far to<br />
the rear and is not visible from the tractor<br />

cab computer. Accessibility for calibration<br />
testing could do with being better but drilling<br />
to calibrated rates is excellent.<br />
Seed <strong>placement</strong> also ticks all boxes.<br />
Most depth control systems on the sur-<br />
veyed machines rely on double disc coulters<br />
followed by press wheels. Drilling<br />
across and along rows is good. A tine bar<br />
was not reported to be lacking because<br />
covering-up was optimum anyway. The<br />
only criticism raised concerned the coulter<br />
pressure control system, which some found<br />
too cumbersome to use.<br />
