Offset pads

Well Iam cleaning the barn to have room to tear my 977 apart 😮 to repair a bevel gear bearing(it aan't good) while apart I want to replace grouser pads from three bar to two bar My ? is I have 14 inch pads now can I buy 18 inch then cut them to be offset 2 in. to the outside This thing is so heavy it sinks if the soil is the least bit wet
Will I kill the pins/bushing Or should I keep the three bar and width🙄

When I was working for Caterpillar in the early 60's, Cat built some special tracks for some D6's that were being used in the phosphate mines. The pads were offset 1.75". After about 3 months we restored them to the original tracks because it was causing extreme wear on the rollers, idlers and sprockets. One of the tractors actually twisted a frame rail. The operators also complained that the tractors did not steer very well, mushy was the term they used. The only benefit was job security to the mechanics who had to repair the machines.
