Land Wheels
The land wheels can be either fixed or steerable. A proximity sensor fitted to the RH
wheel axle monitors the forward speed of the planter.
On machines with steerable wheels, a wheel indicator is fitted to assist the operator.
The land wheels must be set to straddle the rows.
The distance between the LH and RH wheels can be set between 68” (172cm) to 80”
(203cm) on a 2-row machine, and between 72” (183cm) to 80” (203cm) on a 3-row
machine.
To adjust the land wheels:
With the tractor and planter outfit on firm, level ground, raise the planter wheels clear
of the ground and place supports under the front beam (item 3, fig 4) and rear beam
(item 4, fig 4).
WARNING: Never work under the machine when raised on the
tractor 3-point linkage. Always use additional supports.
Loosen the axle mounting clamps (item 1, fig 5) and slide the wheel unit out to the
desired position symmetrical about the centre of the machine. Finally, retighten the
clamps.
