A gate entry system that includes a gate and a gate drive system mounted to a gate post and including a drive roller and a passive roller is disclosed. In specific implementations of the gate entry system, extension rollers may be removably coupled to one or both of the drive roller and passive roller. Opposing sides of the gate may be in constant direct contact with the drive roller (or any extensions coupled thereto) and the passive roller (or any extensions coupled thereto). Rotation of the drive roller when the gate is between the passive roller and drive roller acts to move the gate in a linear direction. The drive roller may include a shaft coupler and a threaded female coupling opposite the shaft coupler. A threaded male coupling of an extension roller may be threadedly coupled to the drive roller threaded female coupling.
