    Hybrid Rotary Cutter Proof of Concept

    Yes! The Van Wamel offset mower is the same as I built. Woods did it years ago too with their D080 offset version. It just didn't exist sized for a small, low powered tractor.

    When is a Chain at End of Life

    My oldest son is 40 today too... happy birthday! I burn 8 cords/yr. Running a hot saw with a sharp chain brings me back to when I was a kid and could handle a screaming 2 stroke motocross bike. I'd kill myself on a moto bike now but feeling those big chips smack my legs make me  feel like a...

    Compact sub compact?

    Yup...  everything is running bearings in aluminum housings anymore: automotive, motorcycles, ATV, utv, snowmobile, watercraft, etc. They run in oil; if designed right it's a non-issue. My 2000 series runs an aluminum trans housing AND a cooler. It even called for an initial 50hr service...

    Compact sub compact?

    Yes, for transaxles! Retired JD engineer here... had transaxle responsibility too. Aluminum is used because it rejects heat much better than cast iron; this is the number one killer of the transmission (that and not changing fluid). Strength is not an issue as it is easy to add adequate...

    Woods 90" Finish Mower RD990X windrows cuttings

    Clippings often "snag" on cut quality issues going on underneath causing the windrow. Rake a little of the windrow off and inspect the cut underneath. You may find the root cause there. Know that 'forward sweep' (region where the blades are going forward) is the weakest part of the cut. The...

    Tire Tread and Gear Ratios

    With the center of the rear axle being the origin (0,0,0) of the tractor model, the SLR determines the "ground plane".... all the lift systems relate to ground. Pretty big deal getting a good SLR number. "Grown tire" is another number the tire manufacturers used to provide... not so much in...

    Tire Tread and Gear Ratios

    When I designed tractors at Deere... we'd use SLR: static loaded radius. In later years it got more difficult to get precise numbers from the manufacturers on their tires. Suppliers moving out of the segment? Production moving to low cost countries?

    Tire Tread and Gear Ratios

    It's common to overdrive the front wheels 3% over the rears.... less it won't turn... more = front tire wear.

    Spindle replacements for John Deere X380

    Ha... I've been retired 9 years. I dont remember. What does the owners manual say? I grease the spindles on my GX335 once every Spring (but I only mow about 25hrs/yr).

    Hybrid Rotary Cutter Proof of Concept

    I'm sorry, I don't know what "it" is. I also dont see the "black tick marks" and what they represent. Here's all we'll need: A pic (or your visual description) of the tractor/mower (shot from the rear) with a stripe coming out. How stripe aligns with LH tractor tire (full width? Starts at...

    Hybrid Rotary Cutter Proof of Concept

    "Back-sweep" is the portion of the blade going backward as the deck moves forward. This is typically the best cutting region on each blade. The deck (and tractor) is pushing the material forward as the deck moves through it. Easy for the blade to then "go against the grain" and cut cleanly...

    Hybrid Rotary Cutter Proof of Concept

    I'd shift the mower... if mower tongue is fixed, could you prepare a crossbar and bolt it to the tractor hitch? Hook up the mower shifted left? It will be the most impactful thing to do.
