1-2 DESCRIPTION
The RDTH cutters (Figure 1-1) are grooming mow-
ers intended for cutting lawns, golf courses, athletic
fields, or any maintained area where a clean, uni-
form finish is desired. Uplift blades form a suction
during operation to lift the grass before cutting it.
The caster wheel arrangement along with the float-
ing lift linkage and optional front roller, all work
together to give an even cut and minimize scalping.
Power from the tractor is transmitted through a trian-
gular, telescoping driveline to the 90 degree gear-
box. It is then passed to the spindle housings by a
single, B-section, Kevlar reinforced belt. Drivetrain
protection is provided by belt slippage.
