Background : The Carco 30B is regarded as one of the BEST winches available in the 30,000 lb weight class. All the small dozers made by the the major manufactures like Komatsu, Deere, CAT, CASE, and Dresser were equipped with PTO drives standard before the mid 2000's. The big change in the industry around 2005 was that most of the manufactures next generation dozers were no longer equipped with a PTO shaft option. This change in the industry would foreshadow the end of Carco 30B production without any new dozers able to accept the PTO drive configuration. This was a sad change for many operators because the engine HP transfer to the winch via PTO is hard to match. The replacement winches for current production tractors are Hydraulic drive models where the winch drum is driven from a hydraulic motor powered from the tractor hydraulic system. Unless the tractor is specially designed with a very high flow and high performance aux hydraulic system the winch performance of a hydraulic winch will never match the PTO drive winches like the Carco 30B. For Applications like Logging or Skidding, the PTO drive winch will pull more weight at a faster line speed than almost all the Hydraulic winches on the market. Since the PTO drive winch has it's own small hydraulic pump internally and doesn't share hydraulic fluid with the tractor, the Carco 30B doesn't have to worry about overheating the hydraulic system either. Relative to the cost of the dozer these small PTO winches can be costly, but those in the industry know that they offer much better performance than most of the new winches that are still 2 or 3 times the cost of a Rebuilt Carco 30B.
This Winch : This Carco 30B was build for a Komatsu D32/D38/D39 crawlers. It has the right gear ratio and equipped with Power in, Power out, and Freespool. Most of these winches were only power in, and the power out was an additional option that cost extra back in 1998. It arrived complete with remote valve, hand levers, and brackets which is very rare for these winches. It has not been used on a dozer for a while. For PTO winches, the brake can be fussed together over time, so this winch needs to be gone through before installation on any tractors. We also need to get the PTO shaft to complete an installation package, so there will be a lead time for some parts and shop work before the winch would be ready for installation. The drum speed for this gear ratio can be a bit fast for recovery work, so if you're going to use this exclusively for recovery of stuck machines burried in the mud we suggest using a snatch blow to lower the line speed, increase control, and increase line pulling power.
Conclusion : It has proven history of durability, long production history, high line pulls, simple design, and good product support for most of the components. It's been on the market a long time with several updates over the years to improve a couple weak points. There are hydraulic winches that offer better control for inching operation and variable line speed, but the Carco 30B has been proven over decades to be a fantastic winch in the logging and recovery application. PTO winches like the Carco 30B almost always out pull a hydraulic winch because the power available to the winch VIA the tractor PTO shaft is much greater than the power available VIA the the dozer ripper valve or tractor hydraulic pump. If you want a proven and durable winch that won't let you down the 30B is a fantastic choice.
