I looked into converting my JD 1209 to what JD calls non clogs, but are stub guards to everyone else. Just the guards and hold downs came out to nearly $600 from Webb and an additional $247 for the sickle bar and head. Total conversion cost was $839.46. This was last October. Everything has gone up so probably closer to $800 for just the guards, which is all I would need since already have a new sickle bar, hold downs, and wear plates. For now it was less costly to replace 3 guards, the wear plates, hold downs and bar. Later on if I determine it will be a better solution, IE, guards on it clog a lot, then I will go that route, but for now, just getting it to full working order is enough.
