As a result of field experience, we have found that the action of the scrubbing brushes on the TTV4555 allows water/ chemicals to be sprayed onto the rear transaxle drive unit during operation.
To prevent this all new machines will be fitted with an additional splash guard which can also be retro-fitted if required.
The front drive system of the TTV678 is in itself brilliant, allowing great machine manoeuvrability especially in tight areas. Because the wheel is used so extensively in normal operation we have field tested a new, improved tyre which will now be fitted to all new machines as standard.
The new RED tyre provides improved traction, longer operating life, and is more resistant to the variety of chemicals used by different users.
