Differences between 4012 and 1635.
Hi ABC,
I compared the Rayco 1635 and the carlton SP4012. The carlton model you mentioned is bigger than the 4012, so I wasn't considering that one.
My comparison of features between the 1635 and 4012 showed.
1. (small point) The 4012 has a 10 gallon fuel tank vs. the 1635's 6 gallon.
2. The 4012 has a hydraulic tonque extension to advanc the cutter wheel into the stump, the 1635 doesn't have this. I believe you drive it foward into the stump as you cut. The Carlton tongue extension allows for a more controlled and smooth cuts.
3. The 4012 has hydraulic drive. The 1635 has some sort of chain drive. (I haven't seen this myself, I recall reading it here somewhere.) You'd be familiar with what comes on the Rayco's.
4.(small point) The extra wheels that come on the 4012 remove with one 1.5" bolt each. on the 1635, each wheel is removed with 2 small bolts each.
5. The 4012 is constructed with 1/8" and 1/4" sheet steel throughout. The 1635 is square steel tubing and the main cover is thin gauge sheet metal. The weight of the 4012 is 1,600 lbs. vs. the 1,300 lbs for the 1635. The overall construction, the tongue extension assembly, the hydraulic drive are what makes for the higher weight.
6. The Carlton SP 4012 is available from the factory with the Dura-disk for an upgrade cost of $700. If you want to add one to the 1635, you have to order one from newriverequip.com for $1,200 plus shipping.
7.(small point) The 4012 is available is multiple colors. I got mine in red. The 1635 is in the standard color only.
8. The only selling point I could find for the 1635 was price. Rayco will come down alot on the 1635. Carlton won't. I really felt that the Carlton is the better machine(between the 4012 and the 1635, anyway.), so that's what I bought.
The Carlton 7015 is a bigger machine than either the 4012 or the Rayco 1635. Which is the size machine I was looking at.
Take care,
Mitch
