Where can I get parts?

Other User-Submitted Questions:

  1. How can I cut down on windrowing?
  2. We recently bought a tractor with a PTO for our 55 acre ranch in Hawaii. The pastures have been neglected for 3 years. The 4-foot mower deck that came with the tractor is not in salvageable shape. I'd like a deck we can use to cut soft brush up to 4 feet high now and use for mowing in the orchard later. What should I use? Aloha & Thank you.
  3. What cutting diameter is the T-104 pull-type rated at? Thanks!
  4. I have a 245 Massey-Ferguson rated at 42 horsepower. It should be around 4,000 lbs., also cat 1 hitch only. Would it handle the 5 foot cutter?
  5. What is the HP rating of the gearboxes on the T-180? What size brush is it rated for, what is the weight of the machine?
  6. I just purchased a 7210. In your operator's manual and parts book there is no section that shows all grease fittings. Is it possible to get a section that shows all fittings?
  7. I have 15 acres to mow. I am considering a Kubota L4330 (34.5 PTO HP). Will this tractor handle the 7210? Or should I go with the 6010? I would like some more information on the clutch mechanism and what I can expect to happen if I hit a rock.
  8. I have an area that I need to cut the grass, but it has a lot of rocks. Is there a different blade design or chain blade that could be used to prevent damage?
  9. I have narrowed my purchase choice to a Bush-Whacker Model 6010 or a Bush Hog Model 305. Cutting capacity of the 305 is 3-inch diameter. What is the cutting capacity of your Model 6010?
  10. I need to update the cutter on our tractor and was looking to buy a 6 foot unit to fit our John Deer 1947 B. Do you have a model that would do fit that tractor?
  11. The hitch on my batwing hangs down at an angle which wears the clevis and drawbar. I saw a new hitch of yours that's supposed to operate level. How long have you been buiding it? Will it fit your older model batwing Bush-Whackers?




1. Our cutters do not windrow as much as other brand name cutters. The reason is our deck design. As you can see from the pictures on our literature, our deck designs follow the outer rotation of the cutting blades and have very little wasted space underneath the deck which allows a better vacuuming and discharge of the materials being cut. Our blade design is that of a shoulder blade which also creates an updraft or a vacuum under the deck cutting the materials finer and discharging more evenly.  Our cutters can also be ordered with a mulching kit which will help decrease windrowing even further.

Windrowing can happen when the materials being cut are 12 inches or more in height, are damp, or are a substance that is gummy. Dull blades or cutting at a fast ground speed can also cause windrowing. Some materials such as wheat stubble or corn stalks windrow more than others.

Bottom line, cutting grass that is 5 or 6 inches tall down to 2 or 3 inches should produce a nice smooth clean cut with very little or no windrowing.
2. Thanks for your interest. We recommend the 8410, which has a 7-foot cut, leaves a pretty smooth cut on grass and soft brush but will also cut through heavier stuff. If your tractor HP is large enough you might be able to pull one of our larger cutters and cut down on your mowing time.

3. The T-104P is rated to cut two-inch brush. Thanks for asking!

4. The 5 footer requires 35 HP and should work fine. To find your nearest dealer, just click here.

5. Thanks for your question. Gearboxes are rated 250HP (divider) and 190HP (spindles). It has a 4" cut (best in the industry)
and a weight of 4,990 lb. To find your nearest dealer (we have plenty in Missouri), click here.

6. Actually, we have a four foot finishing mower, you can see the details at this link. At this point we have no plans to produce a 4-foot heavy-duty cutter since it would probably be too heavy for the kind of tractor that you're thinking of. Thanks for thinking of us, though!
7. The 7210 has four fittings: the tail wheel hub, the A-frame tube and one on each U-joint. You'll need to pull the drive shaft apart and grease the tubing where it telescopes. The way to check the gear lube is by pulling the check plug from the gear box.

8. The Bush-Whacker Model 6010 will be more suitable for a 34.5 HP tractor. You may need some front end weights unless you have a loader attachment.

The clutch is designed to slip when more torque is required than is usually necessary for simple mowing, such as when traveling in too high a gear and mowing heavy growth at the same time. Or if you get hidden fence wire, cable, etc. wrapped around the blade carrier. The slip clutch helps prevent drive shaft and tractor damage.

What can you expect to happen if you hit a rock? There are a lot of variables. Size and composition of the rock, blade tip speed, angle of contact, etc. Some rocks will shatter and some rocks can be ejected at high speeds. Always inspect the mowing area prior to operation of ANY rotary mower and remove any rocks or debris that could be encountered. Chain guards are standard equipment on all Bush-Whackers and will contain most objects struck, but it is imperative to keep bystanders, pets and livestock far removed from the area being mowed.

9. Not really. Bush-Whacker recommends that you remove the rocks from the area before mowing. Not only can rocks damage the machine, but more importantly, they can be ejected at high speeds, resulting in personal injury or even death. Always inspect the mowing area prior to the operation of ANY rotary mower. If rocks or gravel, wire, rope, bricks, or similar objects are found, remove them immediately before operation.

10. The cutting capacity of our model 6010 unit is 4 inches. There are many additional advantages of choosing the Bush-Whacker 6010 over the Bush Hog 305.
  • First, the Bush-Whacker gearbox is rated 190 HP vs. the Bush Hog 80 HP.
  • The Bush-Whacker has a wider range in cutting heights, and it has a higher blade tip speed of 15,500 fpm.
  • Standard equipment on the Bush-Whacker 6010 that is optional on the Bush Hog 305 are front and rear chain guards and drive shafts with slip clutches.
  • Unique standard features on the Bush-Whacker 6010 are 1/4-inch I-Beam side skirts with replaceable skid shoes, and cutting blades with 3/4-inch thickness around the bolt hole for stronger, safer blades.
  • We install our gear box on a 1/2-inch steel plate for a more durable, longer lasting cutter. We also have a structural frame that is 2-inch by 3-inch tubing, 1/4-inch thick. I hope this will help you decide on the purchase of a Bush-Whacker product.

11. The 1947 John Deere Model B tractors were rated about 24 HP. For our smallest Bush-Whacker, the Model 6010P, we recommend a minimum of 35 HP.
12. We have been making the new hitch you have seen for about a year now. It will only interchange with the swivel type tongues. The part number is 4871 swivel and clevis. The swivel has to be changed as well.
