CHAPTER 12 STORAGE

At the end of the harvesting season it is suggested that the following steps be performed:

1.The Electrical Control Box should be stored in a dry place. Install the Dust Caps, where provided, over the ends of the Wire Harness Plug Connectors.

2.Clean the Harvester thoroughly of all dirt, trash, excess grease and any other material that will absorb water and cause rust.

3.Thoroughly lubricate the Harvester as indicated in the Lubrication chapter.

4.Clean and oil all Drive Chains.

5.Paint all the parts from which the paint has been worn to prevent rust.

6.Order and replace any required parts so the Harvester will be ready to operate the next season.

7.Store the Harvester in a dry place where it is neither exposed to weather nor livestock.

8.Release tension on the Blower Drive Belt if the Harvester is going to be out of operation for a long period of time.

Protection Of Unpainted Surfaces

Apply a rust preventative oil or grease to the following unpainted surfaces:

1.The Front Telescoping Drive Yoke Hub at the PTO drive end.

2.The Front Bevel Gearbox Shaft Splines.

3.All Drive Chains and Sprockets.

4.The Length–of–Cut Sprocket Splined Shaft.

Chapter 13 Troubleshooting

NOTE: This Troubleshooting guide presents problems, causes and suggested remedies beyond the extent of loose, worn or missing parts and it was developed with the understanding that the machine is in otherwise good operating condition. Refer to the index at the back of this manual for Chapter and Topic page references. For additional assistance, BE SURE to contact your local GEHL dealer.

Blower

Problem Cause Remedy

Forage is NOT being blown adequately or Spout is plugging.

Operating too far below rated PTO speed.

Operate the tractor at the proper PTO speed. Check the Spinner Drive Chain to see if it is on the Sprockets. If a Speed Monitor is present: Check that Speed Monitor is plugged-in. Check that all electrical Plugs are connected or, if the Speed Monitor is NOT functioning, have the unit checked per the electrical troubleshooting information provided to the dealer.

PTO is being disengaged before the Harvester is cleaned-out.

Blower Rimsheet and/or Spout is gummed-up.

Disengage PTO only after all forage is cleaned-out.

Remove gum and dirt by either scraping it out or by running very wet forage or freshly cut crop through it; consult with your dealer for information on a Water Tank system.

Blower Paddles are NOT set-out to the Rimsheet. Adjust Paddles; refer to Adjustments chapter.

Blower Belt slipping. Check Belt for wear and/or oil contamination and check for proper Idler alignment.

Spout Liner is worn through. Replace Liner.

Spout Horizontal Extension is interfering. Correct the Extension mounting, as required; refer to the Set-up & Assembly chapter.

Cap is being tipped-down too far. Operate the Cap in a higher position.

Blower Belt is coming off.

PTO is being engaged at too high an RPM. Always engage the PTO at tractor idle.

Blower Fan is obstructed. Check the Fan to see if it turns freely.

Belt Idler is tipped and/or NOT in line. Position Idler perpendicular and in-line with Belt.

Blower Fan Blades are striking Blower Sidesheets.

Locking Collars on Blower Bearings are loose.

Center the Fan and tighten the Bearing Lock Collars.

Length-of-Cut is too long. Reduce the Length-of–Cut; see Adjustments chapter.

Stem Guides NOT correctly set to the Knives.

Set the Guides from 1/32 to 1/16″ from the cutting edge of the Cutterbar.

CUTTING CYLINDER (continued)

Problem Cause Remedy
