Frequently Asked Questions
What replacement seat fits a Komatsu PC210 or PC200 excavator?
Broken Tractor carries suspension seats that fit the Komatsu PC200-6, PC200-7, PC210-6 and PC210-7, including SKUs C62522-Komatsu, K4122-Komatsu and the vinyl K5121-Komatsu. The same seats also fit the PC220, PC228US-3 and PC240 in the -6 and -7 generations. Fitment can vary by model and serial number, so match the part number on your old seat or confirm with our parts team at (800) 909-7060 before ordering.
Is there a Komatsu excavator seat for sale that fits a PC300?
Yes, we offer replacement suspension seats for the Komatsu PC300-6 and PC300-7, along with the PC270-7, PC308US-3 and PC350-7. Each seat uses full mechanical suspension to dampen vibration and shock during long shifts. Check the fitment list on each product, or match your original part number, to confirm the right seat for your machine.
Which Komatsu OEM seat part numbers do your replacement seats cross-reference?
Our K4122-Komatsu and K5121-Komatsu seats cross-reference Komatsu numbers 20Y-57-31100, 20Y-57-31400, 22B-57-11400, 23B-57-31201, 23B-57-31301, 208-57-71100, 208-57-71101 and 208-57-71102. If your old seat carries one of these numbers, it is a good way to identify the correct replacement. Always compare the number on your existing seat with the product listing before ordering.
Can I get a Komatsu excavator replacement seat in fabric or vinyl?
Yes, Broken Tractor offers Komatsu excavator suspension seats in both fabric and vinyl upholstery. The K5121-Komatsu is the vinyl suspension version, and fabric suspension versions are also available. Both styles fit a wide range of PC-series excavators, from the PC120-6 up to the PC600-7.
Komatsu excavator model numbers explained: what does the -6, -7 or -8 mean?
The number after the dash in a Komatsu PC-series model, such as PC200-6 or PC200-7, identifies the machine's generation. Our replacement seats cover -6, -7 and -8 generation PC-series excavators, including the PC130-8, PC138US-8 and PC160-8. Because seat fitment can change between generations, confirm your full model number, including the dash number, when choosing a seat.
