Guys, what can you tell me about a 630 gas COM? Narrow front. What are they worth? Anything to pay close attention too? Good/bad? Looking for a row crop odd job tractor for the farm.

I think the 630 could be an excellent odd job tractor if your needs don't exceed 50 hp. The 188G engine, transmission and rear-end are all bulletproof for the kind of work you're talking about. When used for heavy work, some had problems with the drive train. Arguably, Case found the limit of the design with the 50+ hp of the 630, when the initial design (300 Roundnose) was rated closer to 30 hp.

If the COM converter is in good condition, you've got a winner. If you can't shift the tractor into gear by releasing pressure (depressing the clutch) without significant grinding, be careful. The problem could be warped plates in the clutch pack. Similarly, if the converter won't maintain pressure when in direct drive, which means the direct drive clutch won't hold,….the cost of repairs could be substantial if you can find the parts.

My personal bias is the COM system in these tractors is highly desirable, and normally very reliable. However, if it is in need of repair, you're probably better off moving on to the next opportunity.

Prices can range from $1500 for one needing lots of attention, to upwards of $6000 for one in excellent condition. $2500 to 4500 seems to get most in good operating condition.

Joe covered all the bases very well. A 630 is a realy nice sized chore tractor. NF might be an issue with a FEL, but for any other job the NF would be much more manurverable.
