Lightweight in design and engineered for everyday use, the ES-34SL delivers exceptional cut quality while reducing soil compaction.

Front Roller
Smooth Front Roller
This option replaces the standard weile roller with a smooth roller. A smooth roller distributes the machine weight more evenly and is therefore less aggressive on the turf. Use a smooth roller on well maintained level turf, or if your turf is stressed, recently aerated or in soft ground conditions
Rear Roller
Rubber Coated Rear Roller
This option replaces the standard smooth rear roller for a rubber coated version. Ideal when frequently transporting the mower between sites or over rough ground to reduce damage to the rear roller. Also decreases wet material, such as grass and mud, sticking to it compared to the smooth roller
