Tyrone’s truck only holds 1 crate (100 items) by default, but you can increase its capacity to carry more stuff to and from Bellflower Meadow.
From your Shop > Gear tab in main farm, you can buy a Utility Trailer, then up to 7 crates, with each crate holding a maximum of 100 items.
The trailer and crates require coins, but also Green Vouchers and Purple Vouchers.
Buy the trailer, then place it in front of your farm. Then, click on your trailer and a pop-up window will open allowing you to buy up to 7 crates.
