I just bought a Bushhog Razor Back 60" cutter for my B7500. I have never used a rotary cutter before. I am having a great deal of difficulty determining how to connect the cutter to the tractor to get it level. I have read several posts tonight and see reference to setting the 3ph then attaching the toplink. My understanding from reading the manual for my tractor is that you use the adjuster link on the right hand lower arm to level an implement and use the top link for height. If I set the lower links level and use the top link to adjust height one of two things occurs. If I set the top link so I can transport the cutter with the rear wheel off the ground when I lower the unit the front is on the ground and the rear much higher. If I set the top link so the cutter is level on the ground I cannot lift it clear. Can someone explain to me in easy to understand terms how to connect this thing to my tractor correctly. Thanks.

I perfer the 4' for here in NY but you want to cut with the front as it will only cut once. When the rear is lower then you are making many cuts and using more fuel and power. Don't worry about the rear wheel coming off the ground. ....

Hi Hal
I have the same tractor and use it with a bush hog (Rotary Mower). I know what you are going through.
The first problem you have to overcome is the fact that the B7500 does not have position control on it's 3PT hitch. I solved that with a Mower Deck Stabilizer from Zerco. This kit is basically a set of chains to limit the drop of the front of the deck. I purchased it from a local Kubota dealer, but dealers in your area should be able to find a similar kit. You would need to get a long top pin from Tractor Supply or someone else to pin the tractor end of the top link since there will need to be a metal plate on each side of it. On each bottom pin there is another plate with a chain attach. After connecting the bottom pins raise the deck and attach the chains. NOW you have a limit on the drop.
Once you have the front height set you can adjust the rear wheel. Remember, the front needs to be a little lower that the rear. About 1".

Hal, two points on your deck setup;
First, the deck should NOT be level when you are cutting, the front edge should be a little lower, , 2-3" is plenty, the mower will cut far better and easier this way.
Secondly, if the ground is a little less than flat & level it is better, IMHO, and safer to use a piece of chain for the upper link on the 3pth. Use the lift arms and the adjustable tail-wheel to set cutting height, the upper link is only there to lift the cutter up completely clear of the ground. In this method the cutter can move with the ground and you will have a better cut and far less chance of damging the cutter or 3pth on rough ground or ditches, etc.
Best of luck. ....

I solved the problem of constant adjustment by using a hydraulic top link. This way you have infinite on-the-fly adjustment from the seat, not only for the mower, but for anything else. You will need rear hyd. remotes for it though. ....

Earthworks, how does a hydraulic toplink do anything for adjusting the height of the cutter?
The height is adjusted by raising or lowering the tailwheel and lift arms.
If you lengthen or shorten the toplink all you do is change the angle of the cutter relative to the ground. This doesn't accomplish much since the cutter is designed to run with the front edge just slightly lower than the back.
It also wouldn't help prevent damage if the back wheels went down into a depression such as a ditch and the cutter was being overloaded.
Best of luck. ....

Murf: thanks for the suggestion on the chain. Do I just remove the top link and put a chain in its place. I could not get the cutter anywhere near level using the factory attachement points. I cut them off and lowered them about 6 inches and could then get the 7500 to lift enough to get so I could level it. Really solved the problem and upgraded to a new L3130 afterwards. ....

Murf: You are right abou the tail wheel. I should have been specific. I tend to do a lot of hilly, not-level-land cutting. And I do a lot of brush cutting up to 3" where I might start a 2-3 feet off the ground and slowly drop the cutter down to mulch or chip the tree/brush. With the hydraulic top link I can back into and up (and down) embankments and tilt the cutter to the desired position without the front digging into the ground. But truth be told the hydraulic top link is also good for fine tuning the cutter even on level ground and especially when going from one implement to another as far jumping off the tractor to adjust the toplink when switching implements. ....
