Fishfiles 20,141 Posted December 23, 2020 Welcome to the forum Grantlac , you got me on this reduction question , usually I know a bit about reductions , but the 420 with a secondary reduction is something I have never heard about yet , @jeepwm69 might know , just gave him a mention so maybe he will chime in soon 1 Share this post Link to post Share on other sites

Fishfiles 20,141 Posted December 23, 2020 If anyone would know about a 420 " double " reduction , I would bet it would be Jeremy Lee @ https://www.facebook.com/reductionboss Are you maybe taking about using a 69% reduction in the engine and portals that are 27% reduction , the common portals reductions I see are 15 % and 30 %, would guess a set for a 420 would have to be custom made and upwards of $3,000 a set plus the engine reduction , another $500 + , could see a set up like that going for $4,000 2 Share this post Link to post Share on other sites
Goober 1,555 Posted December 25, 2020 I saw you posted a pic and mentioned portals in the TRX300 thread. I saw the reduction gear set but I didn’t know that’s what they where called. That’s a pretty cool invention. You call them high wheelers? Share this post Link to post Share on other sites

HighWheelers , I like that term , you got the TradeMark on that one !!! You can run portals and not have to use a reduction in the engine as the portals come in different ratios , huge tire guys run both engine reductions and portals ----- but portals are not available for all atvs over the counter , they are avalible mostly for the newer utvs and atvs ---- but builders do build them for certain models , $800-$1,000 a wheel 2 Share this post Link to post Share on other sites
jeepwm69 7,420 Posted December 28, 2020 I've been offline for a few days. I'm guessing he's looking at running a primary GR on the clutch, secondary GR on the secondary. I don't know enough about it to give advice though. I've had Chris Clark build me a 15% primary for my 500 Foreman (same as the 420 GR's) and he can do a 15% secondary too. Reduction Boss on bookface seems to have the biggest selection and the gears are one piece, not welded. Share this post Link to post Share on other sites

Welcome to the forum. What size of tires are on the machine? They gear them down for tall tires so if they have some shorter ones on it, it will be a slow tractor.
