I am looking to buy a used fisher plow for my 88 GMC 1 ton so I can use it as a back up. Do I need to buy brand specific (GMC or Chevy) set up or can I buy whatever I find. I will be having it installed at my local fisher dealer.
LB, some frames for the 7.5 are smaller. some 7.5s will fit the 8ft frame. Have a friend with the small frame on his 90 gmc 3/4 ton and bought a 8ft for it . The A frame on the 8ft was to wide . he had to stay with the 7.5.
All my fisher plows (7.5 rd 7.5 ld 8.5 v-plow 8.5 hd) all fit on my ford so my push plates fit all my plows, as for controls you can run them all off the same control except the v-plow because it needs a different controller and different plug-in due to the extra modes for the v-plow.
Are you talking about a Fisher Minute Mount or the old style conventional mount?
This needs to be clarified before you start talking compatibilty.
All RD Minute Mounts and V-plows will interchange at the push plat. LD plows are smaller at the plates.
I think (not sure) that there were 3 different A-frame to hitch pin mount sizes on conventional plows. I know my Toyota 7ft is 19" and I know of another 7ft with a 22 inch and I thought my old 8-9ft plows had an even bigger spread.
Verify what plow you are asking about.
Also lots of information can be found on the Fisher website.
