THIRTY-THIRD BUCNNIAI* SESSION 113 
Question: If this disc harrow is double and of good quality, will it with- 
out other implement, do a finished job year after year? 
Mr. Dalton: I think it will, sir. 
Mr. Burton: A good many of the growers in our state and in Illinois, 
are using the disc early in the season, and the spring-tooth harrow later 
in the season. We like that arrangement very much, better than the disc 
alone, even the double-action disc; it leaves the ground practically level. 
But we like the spring-tooth harrow; we can gauge the teeth a little 
better than we can on the disc harrow. I know the disc harrows when 
absolutely new and not much growth on the land, work very nicely; but 
in orchards of heavy growth and when the discs get a little dull, the depth 
at which they run is not uniform, while the spring-tooth can be run at a 
uniform depth and leaves the ground absolutely level; and you can gradually 
increase the depth of working when you are thoroughly familiar with It. 
President: Mr. Rupert, have you had any experience in using the Clark 
Cutaway disc? If so, give us the benefit of it. 
Mr. Rupert: Yes., sir; I think it is one of the best tools we have for 
clean cultivation. So far as the depth at which the teeth can be handled, I 
may say; it depends mostly on the way you handle it. You might call it 
dependable — until you get into deep work at least. 
President: How many acres in the orchard? 
Mr. Rupert: Five hundred and forty. 
Question: How about the hillside proposition; will it work successfully 
on a steep hillside and go up and down the hill? We have to work on 
a hillside. 
Mr. Rupert: Yes, sir. 
Mr. Riddell: What tools do you use in this five hundred acre orchard? 
Mr. Rupert: We use different methods of cultivation; in fact, if we 
break the orchard one year well, it is then planted the next. We use rye, 
clover, vetch and clean cultivation in different plots of about, fifty to one 
hundred acres, as the years go by. We only aim to cultivate about one- 
third of the orchard each year, sometimes one-half. We use spring-tooth 
harrows, in case the ground gets too hard. But with the Clark Cutaway, 
thoroughly used both ways in the orchard, you will never need to bother 
with the spring-tooth. 
Question: One more question I would like to ask. How much tractor 
power is required to work, say eight feet wide? What power would we need 
to draw a double-acting harrow the width of eight feet? 
Mr. Burton: Oh, a tractor of fifteen or twenty horse power would 
make it.
