roadapples 6,983 #1 Posted December 5, 2018 I'm missing the spring on my 2 stage blower. It's the one that is vertical just to the right of the mule drive. Do I need this with hydro lift. It seems to work fine without it. Thanks... Share this post Link to post Share on other sites
lynnmor 7,302 #2 Posted December 5, 2018 It takes a 4629 spring available here: spring I would use it to take a lot of load off the lifting parts. 2 Share this post Link to post Share on other sites
JCM 9,130 #3 Posted December 5, 2018 I used the assist spring part # 4629 on my 79361 blower for 10 years until I asked a set-up mechanic where I buy from and was told I did not need to use it on the hydro models with hydraulic lift, so for the last 10 years I have not with no issues. 1 Share this post Link to post Share on other sites

SPINJIM 1,981 #7 Posted December 5, 2018 Because of the weight of the 2-stage blower, the spring really helps relieve the strain on your hydraulics. I use an electric lift on my 2-stage, and have that spring up front as well as the lift assist spring at the back of the lift boom. Sometimes I wish I could have a third spring, because the electric lift sounds like it is straining to do its work. Without that front spring, you might burst a seal on your hydraulics. It's the same spring that is used at the back of the lift boom, just a little more difficult to install. Jim 2 Share this post Link to post Share on other sites
cleat 5,809 #8 Posted December 5, 2018 Definitely want that one. The one on the lift rod itself is for the manual lift. Lets the blower float, reduces strain, and also the blower lifts very crooked without it as most of the weight is on the right hand side. Cleat 1 2 Share this post Link to post Share on other sites

cleat 5,809 #10 Posted December 5, 2018 There is a little flat bar on each end to keep the spring from popping off. 1 1 Share this post Link to post Share on other sites
