OPERATION

2.3 Tractor Horsepower

The horsepower required to operate the mower depends on several operating factors including the vegetation to be cut, terrain condition, operator experience, condition of the mower and tractor, and other factors. The recommended tractor HP for the TWR-180 is 85 HP, minimum 65 HP. The recommended tractor HP for the TWR-120 is 75 HP, minimum 50 HP. Operating the mower with a tractor that does not have enough power will produce a less desirable cut and may cause tractor engine damage.

2.4 Drawbar

Position the length of the drawbar from the end of the tractor PTO shaft to the drawbar hitch hole according to the operating speed of the mower. If the mower is a 540 RPM unit, position the drawbar length from shaft end to hitch hole at 14”. For 1000 RPM mowers, set the drawbar length at 16” for 21 spline 1-3/8” mowers and at 20” for 1-3/4” 20 spline mowers.

2.5 Tractor Hydraulics

DRAWBAR

OPERATION

The mower deck and wings are raised and lowered with hydraulic cylinders operated by the tractor hydraulic pump. There are several ways to configure the mower hydraulics depending on the number of tractor selective control valves and if they are single or double acting. The mower can be operated on a tractor with a minimum of three single acting circuits. One double acting and two single acting cylinders or a three spool control valve must be used to operate the mower equipped with hydraulic phasing cylinders.

Refer to the assembly and parts section of this manual for hydraulic system set-up or contact an authorized dealer for the best configuration depending on your tractor hydraulic capabilities and your intended mower use.

2.6 Front End Weight

A minimum of 20% total tractor weight must be maintained on the tractor front end at all times. Front end weight is critical to maintain steering control and to prevent the tractor from rearing up while driving. If the front end is too light, add weight until a minimum of 20% total weight is reached on the front tires. Front weights and weight carriers can be purchased through an authorized tractor dealership.
