1-2 DESCRIPTION
The EFM cutters (Figure 1-1) are intended for cutting
lawns or any maintained area where a clean, uni-
form finish is desired. Parallel uplift blades form a
suction during operation to lift the grass before cut-
ting it. The four caster wheel arrangement, along
with the floating lift linkage and optional front mount-
ed 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 and
blades by a single, B-section, Kevlar reinforced belt.
Drivetrain protection is provided by belt slippage.
