At the moment we have Eliet 401s and 501s scarifiers and a 60cm efco which is a bit of a beast. We also have a mccullough push garden / leaf vacuum which is getting on a bit, but refuses to die.
So with smaller lawns, say upto 400sqm, we use the Eliets, make a pass, rake / blow and bag up; then repeat as needed.
For larger lawns, we tend to use the McCullough to collect the scarify waste. Occassionally we'll use our 42" Kubota ride-on, but that struggles with wet waste.
With domestic clients there is always a gate access trade-off; many times a 48" ride on will not fit. Plus people are looking for a good finish and so rough tractor markings are a no go.
For me, an ideal machine size wise would be a westwood/countax ride on, 30cm mowing deck, powered collector and swap out the collector for the scarifier attachment as needed. However, this is not a commercial machine and though it won't have heavy use, longevity is an issue. Also, I'm getting comments from people around the power of the engine not being up to driving the scarifier, and the scarifer not being robust / slipping belts.
So, what do people do and any experience of the westood scarifiers?
