Operate the backhoe. You’ll experience its
smoothness immediately. Its smooth, precise
movements speed up work. The jerky motion of
out-dated, high-maintenance chain wrap designs
used by some competition are a thing of the past
when you buy Bush Hog, eliminated by Bush Hog’s
Performance-Based Engineering.

unique hydraulic metering and integral cylinder oil
ports to automatically cushion the dual swing
cylinders in the last 20 degrees of arc. Movements
are fluid and gentle.
Bush Hog Backhoes use control valves, rated at
8 gallons per minute, on the boom and swing
cylinders so you can do more than one operation
simultaneously.
The greater digging forces of the Bush Hog Backhoes
save time and work. Bush Hog Backhoes deliver
more powerful digging forces than other brands.
Bush Hog digging forces are as much as 29% greater
than competitors. That's as much as 29% more

You can actually see the strength and durability of Bush
Hog® Backhoes. The highest stress areas on the Bush
Hog dipperstick are constructed of high-grade steel
formed in the large, boxed construction that delivers
maximum strength. Booms are massive at the key
stress areas--50% larger than competition. All cylinders
are protected by relief valves. Access to the control valve
is convenient. Bush Hog manufactured buckets feature
2 1/2 inch thick welded cutting edges. Regular duty
buckets for the 665H feature replaceable tooth tips.
Heavy-duty buckets have removable teeth for a smooth
cutting edge. Both regular duty and commercial grade
buckets for the BH650 and BH750 have removable
bucket teeth for a smooth cutting edge. Both regular

Save Stress On Yourself
Bush Hog Backhoes make long days more productive
with comfort that reduces fatigue. The numbers prove
it. The platform provides more room for the operator’s
feet -- 70% more than a popular brand. Vertical plates
keep the operator’s feet secure on the footrest. The
perforated platform increases traction. The operator
mounts the seat easily without having to sling a leg
over it. The seat adjusts forward and aft as well
as up and down.
Smooth operation of the Bush Hog dual swing cylinder
design reduces fatigue for the operator. Superior visibili-
ty allows the operator to see the work without straining
to the left or right to look around the console or the
boom and dipperstick. Bush Hog’s superior digging
forces save stress by getting work done faster.
