40d mysteries

[jinman]

Rat, the class III Boomers have a high and low (gear) range and the Rabbit-Turtle switch provides two other (hydrostatic) ranges by electrically changing swashplate angles. In effect, you have four ranges. The other class II and class I Boomers are different. I believe they all have three (gear) ranges, but I am not sure. Anyhow if a 40D is in low (gear) range, either of the the hydrostatic ranges should be able to back the unloaed tractor up a 20º hill and be able to spin the tires because of the reduced traction the tires have in reverse. I'm not sure if it can be done at 1500 rpm, but 2,000 or above should provide plenty of torque. The description in the original post was not completely clear, but in my opinion, there is something there to get checked by the dealer. What do you think?

The class I's have 2 ranges for hydro trans. The class II have 3.

I agree, sounds like it should be looked at by the dealer. It is covered under warranty & shouldn't cost you anything except transport charges if applicable. Even then, you have a strong case (20 hours) that he should make it right & not charge the transport fee.

My dealer visited my house once & another time brought the tractor back to the shop, both at no cost to me.

If the dealer is going to do a field check, you want to be home so you can show him what the problems are (a demonstration is much more usefull than describing it on the phone)
