Mud Hog Start-Up Procedure Vital to Running Properly

By: TDS Author | Oct 15, 2014 4:34:33 PM

At Mud Hog, we want to ensure that once you have your axle, that you don't run into any unnecessary problems.  So, here is the start-up procedure to help you get up and running for your best harvest!

Start-Up Procedure

After having completed the installation or servicing of the rear wheel drive system on a hydrostatic drive machine, the following start-up procedure must be performed to insure adequate bleeding and flushing of the newly installed or serviced hydraulic components. This procedure also serves to check proper plumbing of the hydraulic circuit.

 IT IS IMPORTANT THAT THESE INSTRUCTIONS BE CARRIED OUT AS SPECIFIED. Any alteration of this procedure will defeat its purpose, which is to bleed air out of the system. Special attention must be given to the ½ inch limited movement of the hydrostatic control lever, as it is critical not to allow excessive oil flow during this procedure. If at any time while performing this procedure, a malfunction occurs that causes the hydrostatic system to be reopened, such as disconnecting a hose of fitting, it is necessary to begin the procedure again at STEP 1.

 STEPS 1-7 of this procedure are performed with the front drive wheels of the machine on the ground and chocked securely and the MUD HOG RWD axle raised and secured such that the rear wheels remain off the ground with sufficient clearance around the machine. At all times maintain proper fluid level in the hydrostatic reservoir.

CHECK CORRECT ROTATION OF MUD HOG

Note:

A)  If wheel(s) rotate reverse - go to STEP 6

B)  If no rotation - go to STEP 5 (DO NOT repeat - check valve)

C)  If wrong rotation - correct forward/reverse circuit - go to STEP 1

D)  If dual speed motors - activate displacement control switch - check for change of speed of MUD HOG tires

 # On Case 2055/2155/2555 Cotton Pickers, lockout switch must be activated to allow E T II valve to be on.  This can be done by pushing the wire from the lockout switch toward 1st and 2nd gear.
