Bit of both Id day Although no sliding, its not very steep and dry as a bone, thats just uselessness cant drive straight. haha Yes theres clumps, but the deck has a mulching kit on it. Which is useless for councils. An OCDC like Mickhippy is saying, is what they need. But yea this ones a full mulch kit. Ill be HIGHLY surprised if the ICD deck will have a clumping issue, but as yet I havnt been able to see as I have only seen 2 in operation now and both had mulch kits on them.
