Shipping Info

Shipping Info

If you’re buying a boxed product, we aim to get your order delivered next working day – UK mainland where possible.

If you’re buying a tractor or ride-on mower – a special order item – it could be slightly longer, as we need to PDI the machine.

We do try and van-deliver these machines if we can, as this gives us a chance to demonstrate the product, and to ensure you’re happy and confident with your purchase.

If we can’t van-deliver your machine, as you’re out of our local delivery area, the tractor will be sent on a pallet via a courage company. They will then contact you directly to book a specific day and time that suits you.
