Adjusting Play between Disks

CQ269020-UN-24MAR06

Disk furrow openers suffer wear during operation. When play appears between furrow opener disks proceed as follows:

1. Remove disks by removing nuts.

2. Remove the necessary amount of washers (A) so that the disks are adjusted.

NOTE: The ideal pressure is when the disks are in contact with little friction.

Offset Disks (B)

When play (X) of more than 1 mm (0.03 in) appears between furrow openers proceed as follows:

1. Remove disks by removing nuts.

2. Remove the necessary amount of washers (A) so that the disks are adjusted as specified. Use a feeler gauge to check play (X).

   Item	Measurement	Specification
   Play between Offset Disks	Play	0,5—1 mm (0.02—0.03 in)

NOTE: Ideal adjustment is when offset disks do not touch each other as contact between disks would lead to premature wear.

Concentric Disks (C)

In this case there should be direct contact between the two disks to increase soil attack and prevent earth from entering between disks.

Place disk sustaining shaft in concentric disk position. Make sure there is slight contact between disks.

NOTE: Excessive contact between disks would lead to premature wear.
