Introduction
Introduction
Land Pride welcomes you to the growing family of new
product owners.
This Disc Mower has been designed with care and built
by skilled workers using quality materials. Proper
assembly, maintenance, and safe operating practices
will help you get years of satisfactory use from the
machine.
Application
The Land Pride Disc Mowers are designed and built to
cut hay, grass, and other cultivated forage crops on
farms,ranches, set-aside acres, and right-of-ways. They
are adapted for 540 rpm 3-point hitch Category II offset
mounting and are Quick-Hitch adaptable. They are
compatible with 35 HP to 80 HP tractors equipped with
live or independent PTO’s. The DM3705 has 5 discs and
an 82" cutting width. The DM3706 has 6 discs and a 96"
cutting width and the DM3707 has 7 discs and a 112"
cutting width.
Land Pride Disc Mowers are designed to deliver good
cuttingperformanceeveninthick,tangled,andwetgrass
conditions. Standard replaceable rock guards provide
cutter bar protection in stony conditions and will greatly
extend cutter bar life. A standard break-away latch will
release, allowing the cutter bar to swing back, if an
obstacle is hit.
Land Pride Disc Mowers are well suited for use in
agricultural regions where humidity and moisture
conditions are typically higher, where there is a potential
for crop entanglement, and where tough ground
