About your tiller search
The tiller rotor may have 4 or six tines on it and it will also depend on the tine spacing on each mounting face of the tiller rotor as well as the individual tine blade coverage(actual width) while tilling per tiller blade.
It all depends upon the 2 types of tiller/slasher tines the manufacturer is using and that is why there is a difference in tine count as one may be using the L type slasher tine and the other is using the S type tine to dig which is more aggressive and breaks the ground more readily with less effort.
The rule is the slower the forward travel the deeper you will suck the tiller in the ground and the more broken your ground will become.
The more times you till the more broken the ground becomes and the more oxygen is allowed to enter the soil as well as the soil amendements like lime, sand and gypsum.
Plase check with Ken Sweet about his line of rototillers as he is sponsor of the forum in good standing and he has been running a sale for his rototiller line this week as well and you will save money on a tiller purchase from him.
The CCM tiller is a very reliable import from Turkey and has a lot of steel in the design. The Maschio is also an excellent tiller.
Another example is the
www.northwesttiller.com company with tillers that penetrate 14 inches deep for one pass operation.
