Finally finished 2019 summer harvest. I’ve been very happy with the 2018 Lexion 760 narrow body and the Macdon FD140, 600 separator hours harvesting wheat, chickpeas, mung beans, sorghum, corn and pigeon peas. Droughted, stressed short lodged crops is all we seem to be harvesting this year. The belt feeder house setup has gone well no visible damage to the belts but we did have a bearing fail on the front feeder house feed drum. We also had a bearing fail on the Sunnybrook impeller right hand side twice, once at 250hrs and again at 600hrs. We turned the chopper knifes at 250hrs and replaced them at 500hrs. Greenstar mapping and steering through Agrigps has worked flawlessly through the 2630 and the 6000 receiver. The SB threshing combo in conjunction with the Auto shutoff, belt feeder and the FD140 has made this combine a very productive machine for us. I’m still having dramas in pigeon peas though, they are the Lexion worst nightmare, we had a very successful desiccation this year using glyphosate and ally, but It’s still like harvesting wire, with a lot of back feeding at the APS drum and feeder house, it was so bad it bent the cover above the feeder house and in front of the APS. No chokes though. Do you think the SB Zaps would fixes that problem Don? I’ve had pretty good run out of the Macdon, but I did have a centre Draper drive roller strip the drive spline out of it and hydraulic motor drive shaft stripped the drive spline off as well, same breakdown, there was no obvious cause, the alignment and bearing on the offside is fine. I’ve replaced the knife sections at 500hrs and I just finished replacing the knife guards with crary gold guards, I’m hoping they’ll improve the efficiency of the knife in light crops with a bit better cut and bit less pod shattering, I’ve pretty much worn out the back of 75% of the Macdon guards, I’m not sure why this has happened so quickly but we have been on the deck in the dirt for much of the life of the head, also the last 7000acres of sorghum has been harvested at ground level in flex mode, that’s got to be a heck of a lot of load on the knife components. I’ve also started to wear holes in the poly floor under the centre draper mat on the leading section of the floor. I run a very light pressure on the adapter springs (1 1/2) header pitch at C-D and the wing balance at a slight frown because of the way the CTF tramlines end up after a couple of years with the centre being higher than the outer 2/3 of the swath. The tramline wheel tracks are pretty deep in a fair few of the fields we harvest anywhere up to 12 inches deep which throws out the whole geometry of the machine while harvesting on the ground. Next year they tell me they’ll have the tracks renovated and it won’t be such a problem, apparently. All up it’s been a pleasant experience, love the Macdon/Lexion combo it’s been a very productive first year, if we could just get get some decent rain for next years crop
