JOHN DEERE – KILLEFERWHEEL-TYPE OFFSET DISK HARROWS “H” SERIES
John Deere Model “70” LP-Gas Hi-Crop with John Deere Killefer 6XH Offset Disk Harrow.
The cut-out disk blades on this
harrow provided more aggressive cutting, while plain blades provided a
smoother finish. Donaldson, Louisiana. April 1955.
The John Deere–Killefer “H” Series Harrows are wheel-carried harrows that not only did a
good job of disking, but were easy to transport from job to job. An offset type of harrow with
gangs set at a fixed angle, the “H” Series was sturdy and built for many years of service. Heavyduty
disk blades; anti-friction or white-iron bearings; proper weight distribution for deep, end-toend
penetration; ample clearance; and rubber-tired depth-gauge wheels were all features that
assured top-notch performance.
A touch on the hydraulic control lever was all it took to raise the harrow for transporting on its
rubber-tired wheels. That was a significant feature in the mid-1950s, and it was especially appreciated
by orchard owners. The hitch was able to be offset to either the left or right as well, permitting
close disking to tree trunks while the tractor was avoiding low-hanging branches.
“H” Series Harrows were ideal for difficult jobs such as tearing down irrigation borders, old beds,
and furrows. The “H” Series was available in four different sizes… The 5H at 5-1/4 feet of cutting
width, 6H at 6 feet, 6XH at 6-3/4 feet, and the 7H at 7-1/2 feet. Disks, spaced nine inches apart,
were available in 20-, 22-, and 24-inch diameters. Harrow weight varied from 1242 to 1912 pounds.
