John Deere 4630 Overview
Production History
John Deere built the 4630 tractor in Waterloo, Iowa, USA, from 1973 to 1977. It’s one of the key models in John Deere’s Generation II line. It brought big upgrades to tractor design and technology for its time. When it first came out, it was the biggest tractor in the entire Generation II series. The factory retail price for the 4630 in its final production year (1977) was $27,080.
Features
The biggest upgrade on the 4630 was the brand-new Sound-Gard cab. This state-of-the-art operator cab set a new bar for comfort and safety in the industry, thanks to its curved design and practical upgrades:
- Lower cabin noise: It cuts down in-cab noise a lot, so operators don’t get tired as easily during long work hours.
- Pressurized cab system: The built-in pressurization keeps dust and dirt out of the cab, letting you work in a much cleaner space.
- All-weather comfort: It comes with tinted glass, plus optional heaters and air conditioning, keeping operators comfortable no matter hot or cold weather.
- Built-in safety protection: The cab is integrated with rollover protection, a huge improvement for on-the-job safety.
On top of that, the 4630 offered an optional hydraulic front-wheel drive assist. This feature adds extra grip and traction, which comes in really handy for tough, rough field conditions.
