Simpleton question alert:-
What are the main differences between a tine drill (kv ts, krm sola, megent) and a tined machine like a Horsch 3co and claydon, as @Clive suggested?
What are you getting on one variety that your not on another?
Claydon is a strip till machine. Not suitable to follow a plough unless well consolidated and it's overkill. 140hp will struggle with 3m. Google it or come and look at mine. The Kuhn/KRM/KV tine drills are light weight mounted machines and 140 hp will pull a 6m with ease. A Horsch CO/Sprinter will have integrated packers and are usually trailed. These won't be quite so good in the wet but will do a bity more cultivation depending on the setup.
