ABSTRACT:
An agricultural roller is disclosed that permits rocks and other obstructions to be compacted into soil. and especially sod fields. In particular, the disclosed agricultural roller employs a pipe on which a plurality of rubber treads are mounted. The substantially solid treads insure that the full weight of the roller is applied to obstructions to press rocks and other obstructing objects into the soil, while at the same time permitting the roller to be towed in the field and on roads at increased speeds as compared with steel rollers. A tongue hitch is also provided to permit easy servicing of the treads.
