Maintenance
The simplest way to extend the lifetime of your harrow and avoid interruptions during
working is to lubricate it properly, as indicated below.
1) Every 24 operating hours, lubricate the articulations through the grease fittings in
the following way:
• Be sure about the lubricant quality, with relation to its efficiency and purity, avoiding
the use of products contaminated by water, dirt or others.
• Remove the remainder old grease around the articulations.
• Clean the grease fittings with a cloth before inserting lubricant and replace the
damaged ones.
• Introduce an enough amount of new grease.
• Use medium consistency grease.
2) The lubrication of the roller bearings should be done in the same aforementioned
period (24 hours).
2.1) The roller bearings with oil bath works in constant lubrication, but it is still necessary
to give them the following attention:
• In a flat place, check the oil level of each bearing before using the harrow for the
first time and every day of the first week.
• Then, start to check weekly.
• Change all the oil every 1,000 operating hours.
• Use only SAE 90 mineral oil.
• The suitable level is when the oil reaches the hole of the plug, being the
harrow in a flat place.
• The oil level on the bearings is 130 ml.
