meadowfield 1,900 #327 Posted January 15, 2016 Belt drive will allow flex. How about using toothed belt/belts? That was on of my earlier plans, but they are not as tolerant to twist as v belts, plus once clogged up they ride over too. Will perservere a little longer 1 Cub Cadet reacted to this Share this post Link to post Share on other sites
Stormin 4,458 #328 Posted January 15, 2016 You can get V belts that have slits, for want of a better description, in them. Share this post Link to post Share on other sites
the showman 4,074 #329 Posted January 15, 2016 Why don't you use belts and make a cover for them to stop the grass and crap getting to them 1 diggerjames reacted to this Share this post Link to post Share on other sites

Wristpin 400 #332 Posted January 16, 2016 Posted this on the wrong thread - Brrr it's cold . Some thoughts on the belt issue. Possibly try using a cogged (not toothed) wedge belt, machining up a pair of deeper profile pulleys to retain the belt within the flanges when it twists and making up two raking fingers pointing into the open side of the pulleys to continuously remove debris before it builds up.

diggerjames 543 #333 Posted January 16, 2016 I now it's a major change but how about two right hand boxes and a mini prop shaft , NICE work tho mate ! Share this post Link to post Share on other sites
ranger 373 #334 Posted January 16, 2016 That was on of my earlier plans, but they are not as tolerant to twist as v belts, plus once clogged up they ride over too. Will perservere a little longer Do you have room to fit a cv/uj joint on the intermediate shaft and anchor it to the rear transmission so the sprockets can stay in line as articulation takes place? Or use a worn chain which will accept an amount of twist Or fit an idler sprocket on the outside run of the chain where it meets and leaves each drive sprocket,4 in total, this may reduce the risk of the chain running off.

Ian 2,417 #335 Posted January 17, 2016 These problems are all part of the fun mate, it's called development 1 diggerjames reacted to this Share this post Link to post Share on other sites
meadowfield 1,900 #336 Posted January 25, 2016 Hence my suggestion of toothed belts. it's keeping them clean Norm, would be a nightmare in mud - plus they aren't designed to run out of line either Posted this on the wrong thread - Brrr it's cold . Some thoughts on the belt issue. Possibly try using a cogged (not toothed) wedge belt, machining up a pair of deeper profile pulleys to retain the belt within the flanges when it twists and making up two raking fingers pointing into the open side of the pulleys to continuously remove debris before it builds up. I thought of cogged v with perhaps some grooves or notches in the pulleys to stop it slippingI now it's a major change but how about two right hand boxes and a mini prop shaft , NICE work tho mate !just not enough room James Do you have room to fit a cv/uj joint on the intermediate shaft and anchor it to the rear transmission so the sprockets can stay in line as articulation takes place? Or use a worn chain which will accept an amount of twist Or fit an idler sprocket on the outside run of the chain where it meets and leaves each drive sprocket,4 in total, this may reduce the risk of the chain running off. I've turned the sides of the sprockets down to allow a greater angle. I think running worn and loose with idlers is the way to go.I ran it again at the weekend and it did better, but it is an extreme angle i'm asking it to do These problems are all part of the fun mate, it's called development I've just finished 4 years of development!!!!!Brief update... Started with a vengeance on the hydraulics. Done the levers Shame every fitting I have is different I think I'll end up changing everything over to jic, as can't adapt the spool valve to metric 4 wurzel, nigel, Cub Cadet and 1 other reacted to this Share this post Link to post Share on other sites
dubscum 38 #337 Posted February 5, 2016 hi mate, nice build! Hope you don't mind me asking what tyres are they ? they look well and i wouldn't mind some like that on mine 1 meadowfield reacted to this Share this post Link to post Share on other sites

meadowfield 1,900 #339 Posted February 7, 2016 After a day of painting, cleaning and making fiddly linkages (not much room in there now) I now have working levers Linkages have equal throw, that's why it looks a little complicated. One crank is 2x longer, but the spool linkage halves this to keep things balanced.Dash decal done too. 7 nigel, ranger, Stormin and 4 others reacted to this Share this post Link to post Share on other sites
