Satvia
Satvia tracked machines by model on PartsForMachines: the VB101R, VB102R and VB150R, listed in the Machinery Parts Finder with rubber tracks matched to each and the price on every listing. The VB150R takes the widest track of the three, and the plate settles which you have.
Satvia rubber tracks: VB101R, VB102R, VB150R
Rubber tracks are listed against the Satvia model with width, pitch and link count on the listing, so a measured old track can be matched from those three figures if the plate has gone.
The Machinery Parts Finder is the route: Satvia, the VB model from the dropdown, then track. A part number goes into the header search. Chassis plate worn, photo to 07754288583 on WhatsApp. The Compatible tab confirms the fit.
Batteries by size head the wider range, then hydraulic oil through the Oil Finder, track-tensioning kit, filters and the rest by specification. Not in the Finder? Ask Simon.
