Oliver Spike-Tooth Harrow 
The Oliver spike-tooth harrows are 
equipped with side latch levers that make it 
easy to control the harrow and provide a 
grip for lifting the sections to clear the 
teeth of trash. 
Oliver Tractor Spring-Tooth Harrow 
The Oliver TPB spring-tooth harrow is 
leverless. A handy, quick-acting screw 
control, such as has been so successful on 
Oliver tractor disc harrows and plows, 
raises and lowers the teeth. This screw 
control is easily operated from the tractor 
seat without dismounting and without loss 
of time. With the outfit moving or stand¬ 
ing, the operator can easily adjust the 
teeth so that they penetrate at just the 
desired depth. The leverless construction 
makes this harrow very suitable for or¬ 
chard work, as there are no levers extend¬ 
ing above the frame to catch on low 
hanging branches. 
Adjustable Hitch 
The hitch can be adjusted so that the 
harrow runs level under all conditions. 
For instance, in very soft ground the hitch 
can be lowered so that the harrow will not 
bury itself. 
T-Bar Frame 
This harrow is equipped with an inverted 
T-bar frame, which greatly increases its 
strength. Fastened to the bottom of the 
frame are steel runners, which extend 
beyond the curve in the frame and protect 
it from wear. When worn, the runners 
are easily replaced.
