We currently run Exmark & Toro WB's. The Exmark Tri-vantage deck is terrible in heavy spring growth or wet turf for clumping, while the Toro SFS is excellent in these conditions. The Exmark tri-vantage is much better than the SFS during mulching season. Can an SFS deck be retofit to an Exmark power unit? Wanted to put an SFS deck on the Exmark in the spring. The Exmark sits idle until the real heavy growth is over. Thanks.
