bmsgaffer 2,043 #26 Posted September 16, 2015 Looks good!You are planning on attaching it to the tractor, right?... If you get a clog, i think that chipper might try to become airborn towards your tractor... or even away from (with the reverse twist)... I would just hate to see something seriously damaged if the chipper tries to stop and the engine doesnt. 3 Share this post Link to post Share on other sites
953 nut 51,486 #27 Posted September 16, 2015 Too bad you don't have a PTO clutch on that 875, not an OSHA approved chipper but being able to disengage it would be a good thing. I agree that some ridged connection to the is a must have, otherwise the torque and vibration from operation will certainly knock the belt out of alignment and turn it into a UFO ( unfriendly flying object). 1 Share this post Link to post Share on other sites
ronhatch 405 #28 Posted September 20, 2015 I would get rid of the bad engine completely and support the impeller properly with a new shaft and a couple of flange or pillow style bearings and drive it with a vee belt off the engine via a clutch. A shear pin in the new impeller shaft and driven pulley would be a must have. As stated before, the unit needs to be mounted solidly to the tractor frame. I'm only familiar with farm tractor PTO's. I think they're only either 550 or 1000 RPM. What is the rpm of the D and is it fast enough to spin a chipper/chopper? Share this post Link to post Share on other sites

tech270154 8 #31 Posted September 25, 2015 Easy to do, but the real question is - would the knives and shreader be able to handle that much torque? They do make chippers that run from tractor PTO's but their internal components are much thicker, to withstand the amount of hp/tque. that the tractor will be delivering. Rob hi ROB what is very important is to control the rpm of the shreader ,i did calculate , same as if it would be the engine max rpm 3600 rpm at full I would get rid of the bad engine completely and support the impeller properly with a new shaft and a couple of flange or pillow style bearings and drive it with a vee belt off the engine via a clutch. A shear pin in the new impeller shaft and driven pulley would be a must have. As stated before, the unit needs to be mounted solidly to the tractor frame. I'm only familiar with farm tractor PTO's.

tech270154 8 #32 Posted September 25, 2015 This project finally came to the top of my list when I saw the amount of blackberry vines I need to dispose of this fall.I stripped the non running engine down including valve removal. I left the piston in.Added a Vee pulley to the flywheel. Some wheel chocks and spacers to tighten the belt. I know the chipper is turning in reverse....I have put a reverse twist in the belt, and the initial test seems OK. Some concerns are the small size of the flywheel key. I have replaced the aluminum shear key with a steel key.The radial loading on the pulley end may be a problem....time will tell. Keep in mind this chipper is for vines, weeds, and leaves. No wood. very job , similar to what i was building, make shure you control your maximum rpm ,that should be aprox 3600 Easy to do, but the real question is - would the knives and shreader be able to handle that much torque?

swarfeater 49 #37 Posted September 30, 2015 did this one last year or so. tilted the chipper 10 degrees and with the idler prevents belt whip that will destroy a belt in a few minutes. ive chopped 3" branches with it. 3 Share this post Link to post Share on other sites
