OPERATION
Before attaching mower to tractor, it will be necessary that each tractor lower hitch arms have freedom of movement that the mower 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 check chains 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 mower warranty. Should your tractor not have a built “float” option, a flexible check chain assembly (optional equipment) will be required. See
Figure ASMP-FL-0019.
On all centered mowers, two flexible check chain assemblies will be necessary to provide “float” to each lift link.
On all offset mowers, one flexible check chain assembly will be necessary to provide “float” to the lift link on the same side that the mower is offset. The other lift link should be the adjustable stiff link furnished with the tractor.
3.5 Front End Weight
Maintain a minimum of 20% total tractor weight on the tractor front end at all times. Front end weight is critical to maintain steering ability and to prevent the front end from rearing up. Consult your authorized tractor dealer for front weights and carriers.
3.6 Power Take Off (PTO)
Only operate the mower on a tractor equipped to operate at 540 rpm PTO speed. Tractors operating at 540 rpm will have a
If operating an older model tractor where the tractor’s transmission and PTO utilize one master clutch, an over- running clutch must be used between the PTO output shaft and the driveline of the mower. Consult an authorized tractor dealer to purchase and install an
