Steve i have john deere 455 and 160 both with mulch decks and decks for collecting
we have been cutting the wet grass ok ,things still get a bit sticky
but works better than collecting and stopping every couple of mins
The X320 in your profile picture looks like it is running a 48" deck and this can be converted to a mulch deck for around £120.00 The kit includes 3 x new blades, and a mulch plug that allows clippings to be recut and left. The blower etc is easy to remove and conversion from collection to mulching will take about 1/2 hour first time around. Lots of our contractors mulch all the time, but getting customers to accept a mulch finish where they have had collection previously can be an issue. The finish is good, but not as good as collecting. The plus sides are massive time saving over collection - typically 40% is quoted and no grass pile to dispose of or take away.
It is time consuming to swap between mulch and collecting so it is not really practical to swap to different modes for different customers even if you went to the extreme of having two decks - one for collecting and one dedicated to mulching.
Unfortunately there are no easy answers to dealing with the extra ordinary grass growth that we have this year.
Hope this helps
It is similar, and you need to fit a mulch boot into place to mulch. This is a big L shaped plastic bung that slides into deck and is held in place with a few wing nuts. Main issue is the blades. The collect blades have a lip to force grass along deck towards the fan. Mulch blades do not have as much throw and would work with dry grass but would be much worse than your current performance in the wet. Collecting blades would wreck the mulch bung when that is in place, so as a minimum the swap would involve changing blades each time you remove and replace mulch bung/fan collection system.
Hope this makes sense.
steve we take the mulch gaurd off the bit with two wing nuts with the holes
then our chute fits in for collecting and we keep the mulching blades on still collects ok
.we have the diesel jd 455 48" cut LT160 42"
collecting blades still work ok on mulching
