INSTALLATION OF REAR MOWER

Before attaching mower to tractor, it will be necessary that each tractor lower hitch arm has freedom of movement so that the mover is completely independent of tractor movement. This will allow the mower to pivot sideways as well as move vertically.

Some tractors provide this “float” by means of an optional slot in the lower end of each lift link, others by lift links which can be made telescopic by changing the position of the pins in the links. Failure to provide “float” may result in failure of the cutterhousing and bearings in the roller, thus voiding the mover warranty. Should your tractor not have a built in “float” option, a flexible lift chain assembly will be required.

On all centered mowers, two flexible lift chain assemblies will be necessary to provide “float” to each lift link.

On all offset mowers, one flexible lift chain assembly will be necessary to provide “float” to the lift link on the same side that the mover is offset. The other lift link should be the adjustable stiff link furnished with the tractor.

After the mower is attached to the tractor’s 3-point hitch, but before the universal slip joint is installed, and with the mover on the ground, adjust the top link of the hitch to make the mower gearbox input shaft parallel to the tractor P.T.O. shaft. This relationship provides optimum operation of the universal joints in the driveline. Driveline that is not parallel to PTO will result in vibration due to the characteristic of a universal joint that results in the output end speeding up and slowing down twice each revolution of the universal jointed shaft. Adjust the top link whenever the cutting height is changed.

1.Tip cutterhousing back and place a block under roller to safely support unit. Remove shipping skids and drive pulley side belt guard fender. If necessary, install knives, as shown, one row at a time. ALL KNIFE PINS ARE INSTALLED WITH THEIR HEADS FACING AWAY FROM THE CUTTERSHAFT PULLEY. This will locate cotter pins where knives cannot reach them when flexing backward. The housing side sheet has a hole in it which allows knife pins to be inserted into end lugs from outside the cutterhousing. After the cotter pin is installed, bend extended prong at a 45 Degree angle with prong parallel to lug. ASMP-FL-0047
