VII. SERVICE AND MAINTENANCE LUBRICATION Leg Bearings Hagie 204 leg assemblies are constructed with upper and lower nylon bearings for suspension telescoping between the inner and outer leg weldments. These bearings must be lubricated to avoid bearing failure and ensure optimal ride quality. There are grease zerks located on the sides of the leg

assemblies, one for the upper bearing (fig. 7.34, item 1) and one for the lower bearing (fig. 7.34, item 2). Greasing both bearings on both front legs daily is very important. During operation of the detasseler, the grease may possibly be wiped off by passing crop leaves, so the bearings should be greased at least twice a day. Suggested times are in the morning

and at noon. If the crop is mature enough, or plant population is high enough, more frequent leg bearing grease application may be required. This will ensure proper lubrication allowing optimal performance.
Steering To steer, the inner leg weldment also pivots inside the outer leg weldment. The tie rods connected to the steering legs have FIG 7.34 grease zerks on both each inner tie rod end (fig 7.35, item 1) and each outer tie rod end (fig. 7.35, item 2). To maintain freely operating steering, they should be greased every 50 hours; check tie rod linkage daily. 2
